Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 6: Identities and addressing
The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
This part specifies the identities and addressing structure of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
There are four categories of identities to be used for identification and addressing in a general DECT environment.
These four categories are:
• Fixed Part (FP) identities;
• Portable Part (PP) identities;
• connection-related identities;
• equipment-related identities.
Fixed part identities and portable part identities are used for:
• access information from fixed parts to portable parts;
• access requests from portable parts;
• identification of portable parts;
• identification of fixed parts and radio fixed parts;
• paging;
• billing.
These identities support:
• different environments, such as residential, public or private;
• supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of
central administration;
• multiple access rights for the same portable;
• large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate
provision of access rights to groups of DECT systems;
• roaming agreements between DECT networks run by the same or different owners/operators;
• indication of handover domains;
• indication of location areas, i.e. paging area;
• indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location
and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for
peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency
call set-up.
Coding of identity information elements for higher layer messages is found in ETSI EN 300 175-5 [5], clause 7.7.User authentication and ciphering need additional key information and is outside the scope of the present document, but
is covered in other parts of ETSI EN 300 175 [1] to [8], e.g. ETSI EN 300 175-7 [7].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.
Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Skupni vmesnik (CI) - 6. del: Identitete in naslavljanje
Ta dokument je eden od delov specifikacije skupnega vmesnika (CI) za digitalne izboljšane brezvrvične telekomunikacije (DECT).
Ta del določa identitete in strukturo naslavljanja za skupni vmesnik za digitalne izboljšane brezvrvične telekomunikacije.
Za identifikacijo in naslavljanje v splošnem okolju digitalnih izboljšanih brezvrvičnih telekomunikacij se uporabljajo štiri kategorije identitet:
Te štiri kategorije so:
• identitete fiksnih delov (FP);
• identitete prenosnih delov (PP);
• identitete, povezane s povezavo;
• identitete, povezane z opremo.
Identitete fiksnih in prenosnih delov se uporabljajo za:
• dostop do informacij iz fiksnih delov v prenosne dele;
• zahteve za dostop iz prenosnih delov;
• identifikacijo prenosnih delov;
• identifikacijo fiksnih delov in radijskih fiksnih delov;
• storitev pozivanja;
• zaračunavanje.
Te identitete podpirajo:
• različna okolja, npr. stanovanjska, javna ali zasebna;
• dobavo globalnih enoličnih identifikacijskih elementov proizvajalcem, montažerjem in upravljavcem na osnovi najmanjšega možnega obsega centralnega skrbništva;
• več pravic za dostop za isto prenosno napravo;
• svobodo proizvajalcev, montažerjev in upravljavcev na področju strukture identitet fiksnih delov, npr. glede omogočanja pravic za dostop skupinam v sistemih digitalnih izboljšanih brezvrvičnih telekomunikacij;
• pogodbe o gostovanju med omrežji digitalnih izboljšanih brezvrvičnih telekomunikacij, ki jih upravljajo isti ali različni lastniki/upravljavci;
• navedbo o domenah za prenose;
• navedbo o področjih lokacij, npr. področju pozivanja;
• navedbo o področjih naročnin javne storitve.
Ta dokument zagotavlja tudi indikatorje dolžine in druga sporočila, ki lahko preglasijo privzeto lokacijo in/ali področje pozivanja, ter navedbe domene, ki jih določa struktura identitet.
Identitete, povezane s povezavo, se uporabljajo za identificiranje primerkov protokola, povezanih s klicem, in komunikacijo v omrežju enakovrednih.
Identitete, povezane z opremo, se uporabljajo za identificiranje ukradenih PP-jev in izpeljavo privzetega šifriranja identitete za nastavitev klicev v sili za PP-je.
Kodiranje informacijskih elementov identitete za sporočila višje plasti je določeno v standardu ETSI EN 300 175-5 [5], točka 7.7. Preverjanje pristnosti uporabnika in kodiranje zahtevata dodatne ključne informacije in sta zunaj obsega tega dokumenta, vendar sta zajeta v drugih delih standarda ETSI EN 300 175 [1] do [8], npr. v ETSI EN 300 175-7 [7]. Ta dokument vključuje novo generacijo digitalnih izboljšanih brezvrvičnih telekomunikacij, nadaljnji razvoj standarda za digitalne izboljšane brezvrvične telekomunikacije, ki uvaja širokopasovni govor, izpopolnjene podatkovne storitve, nove tipe rež in druge tehnične izpopolnitve.

4 General description of FP and PP identities
4.0 Overview
Every radio FP broadcasts for its purpose a unique identity which contains a globally unique (to a service provider)
Access Rights Identity (ARI). Every PP has both a Portable Access Rights Key (PARK) and an International Portable
User Identity (IPUI). These operate as a pair. A PP is allowed to access any radio FP which broadcasts an ARI that can
be identified by any of the portable access rights keys of that PP.
The IPUI is used to identify the portable in the domain defined by its related ARI. The IPUI can either be locally unique
or globally unique.
Figure 4.1 illustrates the identity structure.

Figure 4.1: General identity structure
The common base for the DECT identity structure is the Access Rights Class (ARC) and Access Rights Details (ARD).
These need to be known by both the FP and the PPs. In the FP the ARC and ARD are called Access Rights
Identity (ARI), and in the PP they are called Portable Access Rights Key (PARK). The distinction between PARK and
ARI is that each PARK can have a group of ARDs allocated, PARK{y}. "y" is the value of the PARK length indicator
given in the PP subscription process.
ARD
ARC
"don't care" bits
y bits
Figure 4.2: Structure of PARK{y}
If the ARI is a primary ARI, i.e. PARI, it will form, together with a RFP number, the broadcast identity RFPI. ARIs can
also be less frequently broadcast as Secondary Access Rights Identities (SARIs) and may also be available as Tertiary
Access Rights Identities (TARIs), which are not broadcast, but are accessible upon request.
The PUT and PUN form the PP user's identity, IPUI. This identity can either be globally unique or locally unique. In
addition to IPUIs, shorter temporary identities, TPUIs, may be used for paging.
A PP is identified by its pairs of PARK{y} and IPUI. A PP is only allowed to access a FP if one of its PARKs includes
one of the ARIs of the FP, i.e. the PARI, a SARI or a TARI.
4.1 Combinations of ARIs, PARKs and IPUIs
DECT provides a flexible radio access technology for a large variety of private and public networks or systems. This
leads to different requirements on e.g. sub-system grouping, distribution and installation of equipment, identity
allocations and subscription.
Therefore five access rights classes A to E and a number of IPUIs have been defined to meet the need for a
differentiation in the identity structures.
Table 4.1 gives an overview of likely combinations of the main identities. As described in clause 6.2 some flexibility is
allowed in combinations of the IPUI types, e.g. IPUI type N could be used by a service provider in combination with
any ARC.

5 FP identities
5.0 General
FP identities are used to inform PPs about the identity of a DECT FP and the access rights to that DECT FP and thereby
reduce the number of access attempts from unauthorized portables.
A DECT FP broadcasts this information on the N -channel via all its Radio FPs (RFPs), at least once per multiframe. A
T
PP needs to be able to interpret necessary parts of this broadcast information to detect the access rights to a system or
even access rights agreements between system operators, i.e. operators A and B have a bilateral agreement permitting
their users to roam between their systems. These agreements can change and cannot therefore be stored in PPs without
updating them frequently. Therefore the FP handles access rights information which is embedded in the identity
structure.
The DECT identity structure provides solutions for residential, public and private environments. This can also be
extended to combinations between these environments, e.g. private groups of users within a public DECT network, and
e.g. public users' access to private DECT networks.
The base for the identity structure is formed by the ARCs and the ARDs:
ARC: Shows the type of access to a DECT network, such as public, private or residential.
ARD: This number is unique to the service provider or to the equipment (e.g. in the case of residential and
business applications this number is assigned by the manufacturer). Its structure depends on the ARC.
The ARC and ARD together form the basic identity, the ARI:
ARI: This identity is globally unique to a service provider, and shows the access rights related to this service
provider. This identity may be applied to any number of FP installations. There are three categories of
ARIs.
PARI: Primary ARI has to be broadcast. This is also the most frequently broadcast ARI in order to give a higher
grade of service to users with these access rights. The PARI is broadcast over the N -channel (see note).
T
The PARI (in conjunction with RPN) also carries information about domains of handover and location
areas.
SARI: Secondary ARI. SARIs are less frequently broadcast than PARIs. They are sent as a SARI-list on the
Q -channel. The message used for SARIs (there could be more than one SARI) is described in clause 5.6.
T
TARI: Tertiary ARI. The TARI is not broadcast at all and is only available as a (or in a) "TARI reply" message,
which is an answer to a "TARI request" message including the relevant PARK{y}. See clause 5.6.6 and
ETSI EN 300 175-3 [3], clauses 7.2.5.10 and 7.3.5.2.
NOTE: Several FPs may apply the same ARI. However, as a PARI it has to be geographically unique.
The classification of primary, secondary and tertiary access rights gives the possibility for operators or system owners
to offer their subscribers/users an almost unlimited list of roaming agreements. This classification can be seen as an
iceberg with the PARI visible on the top followed by a less visible SARI list and in the depth the invisible TARIs. The
PP procedure for handling PARIs, SARIs and TARIs is described in clause 8.2.

Structure of ARI, see figure 5.1.
ARC ARD
Figure 5.1: Structure of ARI
ARC: 8 available classes named A - H. Only classes A - E are currently defined.
ARD: Details, depends on the ARC.
One ARI together with a radio FP number, forms the RFPI. The ARI embedded in the RFPI is the PARI.
The RFPI has three purposes:
• to carry the PARI;
• to uniquely identify RFPs geographically;
• to show domains for handover and location areas.
The RFPI is frequently transmitted as bits a8 to a47 in the A-field using the N -channel and has therefore a limitation of
T
40 bits. See ETSI EN 300 175-3 [3], clause 7.2.2.
40 bits
E PARI RPN
a8 a47
Figure 5.2: Structure of RFPI
E: This field indicates if there are any SARIs available. Value yes or no.
RPN: Radio fixed Part Number used for geographical separation.
Handover domains:
For DECT two handover domains are defined: internal handover (bearer and connection handover) to be within a FP,
and external handover to be between FPs. Internal handover is possible between RFPs that have the same PARI in their
RFPIs, i.e. only have changes in the RPN. See figure 5.3.

E PARI RPN
External Internal
handover domain handover domain
Figure 5.3: Indication of handover domains
The connection handover domain is always identical to the internal handover domain. The cluster size defines the
bearer handover domain. A PP regards the cluster size as identical with the internal handover domain, if not else has
been indicated by the optional PT "Bearer handover information", see ETSI EN 300 175-3 [3], clause 7.2.4.3.7. The
RFPI for access rights classes A and C is also used for limited information on handover domains, see clauses 5.1
and 5.3.
External handover provision (by the external network) is indicated using the message defined in
ETSI EN 300 175-3 [3], clause 7.2.3.4.2 with the coding defined in ETSI EN 300 175-5 [5], annex F. A PP can request
the FP for information on PARIs of close by FPs to which external handover is supported, see ETSI EN 300 175-5 [5],
clause 15.7. The information also indicates for each FP if it is synchronized to their own system or not.
ETSI
13 Draft ETSI EN 300 175-6 V2.5.4 (2015-03)
External h/o length indicator:
The external handover length indicator is defined as the x bits of the PARI part of the RFPI, see figure 5.4. The PP is
allowed to make an external handover based upon the <> to FPs with all of the x bits the
same.

E PARI RPN

Figure 5.4: External handover length indicator
Location Areas (LAs):
A Location Area (LA) is defined as x bits of the PARI plus RPN part of the RFPI, see figures 5.5 and 5.6. As soon as
any of these x bits change the PP has entered into a new LA and should do a location update. The x bits are indicated by
the Location Area Level (LAL) indicator.
Location area with LAL = x bits:
RFPI
E PARI RPN

Location Area = x bits of PARI and RPN
Figure 5.5: Location area with LAL = x bits
Default location area:
RFPI
E PARI RPN
Location Area = PARI
Figure 5.6: Default location area
LAL is submitted to a PP as a result of a successful location registration. See ETSI EN 300 175-5 [5]. The PP uses the
default location area in the absence of a LAL.
A location registration at a FP can be permanent or temporary. If the location registration indicates "temporary user
limit" all location registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to
receive the PARI) for more than T601 min. If the location registration indicates "temporary user limit 2" all location
registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to receive the PARI) for
more than T603 seconds. See clause 6.3.
Four different ARCs have been defined. The structure and layout of ARIs and RFPIs related to these groups are
described in the following clauses.
5.1 ARI class A
This class is intended to be used for small residential and private (PBX) single cell FPs and small multi-cell FPs with a
maximum of 7 RFPs. Equipment belonging to this class will probably be sold by non-expert retailers. Therefore the
allocation process of class details needs to be delegated to manufacturers by a common administration.

Figure 5.7: Access rights class A, ARI and RFPI
EMC: Equipment Manufacturer's Code is allocated to each manufacturer by ETSI or by a provider authorized by
ETSI. Upper limit of EMC is 65 535. EMC = 0 shall not be used. The reason why the EMC has 16 bits is
to avoid small manufacturers contending with a long number series. Larger manufacturers could have
more than one EMC allocated.
FPN: Fixed Part Number shall be allocated by the manufacturer as a unique number for each EMC. It has an
upper limit of 131 071, which gives a total of over 8,5 billion globally unique ARIs. FPN = 0 shall not be
used.
RPN: Radio fixed Part Number, this number is allocated by the manufacturer/installer and is used to separate a
maximum of 7 different cells from each other. In case of single cell FPs, RPN = 0. This indicates for a PP
that this FP does not have intercell handover, since there is only one RFP.
This class provides enough FP identities for single cell FPs and small multi cell FPs. This results in a longer ARI than
for all other classes. This ARI is therefore restricted only to be used as a PARI and not as SARI or TARI, see clause 5.6.
The class A DECT FP identity is the ARI part of the RFPI and it shall be globally unique.
NOTE: When adding a WRS to a residential single cell system, the RPN of the FT should change from 0 to a
value in range 1 to 7. If the change is not performed, PPs may consider the FT to be a single cell system
and not initiate handover to the WRS.
5.2 ARI class B
This access rights class is reserved for more complex private installations such as LANs and various types of multi-cell
PABXs. In these environments it is necessary to be able to install new, or replace old, equipment without changing
ARIs or RFPIs. This indicates that ARI B is mainly a system identity that follows a system and not a specific
equipment.
The RFPIs could be allocated directly by the manufacturer, or by dealers, or installers authorized by the manufacturer.
The manufacturer is responsible for distributing ARIs to authorized dealers/installers.

EIC: Equipment Installer's Code is allocated by ETSI to each manufacturer, or by a provider authorized by
ETSI. Large manufacturers could have more than one EIC allocated. The same can also apply for users,
i.e. big companies can have their own EIC codes to be used at their different sites. Upper limit of EIC is
65 535. EIC = 0 shall not be used.
FPN: Fixed Part Number is distributed together with the EIC by the manufacturer to authorized installers.
Upper limit of FPN in example shown in figure 5.8 is nominally 255. The value FPN + PS = 0 shall not
be used as a part of the RFPI.
FPS: Fixed Part Sub-number is allocated by the system operator or installer. There are nominally 15 numbers
available, FPS = 0 is reserved for future use, and shall not be used as a part of the RFPI.
A PP may be given access rights to all FPs with the same FPN, by use of a PARK{y}, where y includes only the FPN,
see clause 6. The border between FPN and FPS bits may vary, but the sum shall be 12 bits, and FPN + FPS shall be
unique for each EIC.
RPN: Radio fixed Part Number, is allocated by the operator or installer from the range 0 to 255. The number of
RFPs per system can be larger than 256 through geographical separation.
The class B DECT FP identity is the ARI part of the RFPI. In most cases, the ARI is globally unique. Within the
domain of a network of FPs controlled by one owner/operator, ARIs do not need to be globally unique, but shall be
geographically unique, to avoid ambiguity at call set-up and handover.
5.3 ARI class C
This ARC is reserved for public access such as 1- and 2-way public access service or local loop.

POC: Public Operator Code, is allocated by ETSI, authorized by ETSI, or by a provider authorized by ETSI and
is assigned to each operator as single codes or, if necessary, in blocks. The upper limit is 65 535. POC = 0
shall not be used. The operator shall provide a means for a PP user to discriminate between a mobile and
a fixed FP, using the "non-static FP" broadcast attribute.
FPN: Is assigned by the FP operator and can be used to define different areas of subscription. Upper limit of
FPN in example shown in figure 5.9 is nominally 255. The value FPN + FPS = 0 shall not be used as a
part of the RFPI. FPNs can be chosen so that a wanted group of subscription areas is accessed by a PP by
one PARK{y}, see clause 6.
FPS: Is allocated by the FP system operator or installer. FPS = 0 shall not be used as a part of the RFPI. There
are nominally 15 numbers available per subscription area, FPN, for geographical separation of multiple
cell FPs. See below on RPN for single cell FPs.
RPN: Is allocated by the operator/installer. Single cell RFPIs have the least significant bit = 0, which is used to
indicate that intercell handover does not exist in this FP. This gives nominally 15 × 128 single cell RFPIs
for geographical separation per subscription area. Multiple cell RFPIs have the least significant bit = 1.
The number of RFPs per FP can be larger than 128 through geographical separation.
The border between FPN and FPS may vary, but the sum shall be 12 bits. If, for example, 31 FPS are wanted

1 Scope
The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
This part specifies the identities and addressing structure of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
There are four categories of identities to be used for identification and addressing in a general DECT environment.
These four categories are:
• Fixed Part (FP) identities;
• Portable Part (PP) identities;
• connection-related identities;
• equipment-related identities.
Fixed part identities and portable part identities are used for:
• access information from fixed parts to portable parts;
• access requests from portable parts;
• identification of portable parts;
• identification of fixed parts and radio fixed parts;
• paging;
• billing.
These identities support:
• different environments, such as residential, public or private;
• supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of
central administration;
• multiple access rights for the same portable;
• large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate
provision of access rights to groups of DECT systems;
• roaming agreements between DECT networks run by the same or different owners/operators;
• indication of handover domains;
• indication of location areas, i.e. paging area;
• indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location
and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for
peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency
call set-up.
Coding of identity information elements for higher layer messages is found in ETSI EN 300 175-5 [5], clause 7.7.
ETSI
7 ETSI EN 300 175-6 V2.6.1 (2015-07)
User authentication and ciphering need additional key information and is outside the scope of the present document, but
is covered in other parts of ETSI EN 300 175 [1] to [8], e.g. ETSI EN 300 175-7 [7].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.

4 General description of FP and PP identities
4.0 Overview
Every radio FP broadcasts for its purpose a unique identity which contains a globally unique (to a service provider)
Access Rights Identity (ARI). Every PP has both a Portable Access Rights Key (PARK) and an International Portable
User Identity (IPUI). These operate as a pair. A PP is allowed to access any radio FP which broadcasts an ARI that can
be identified by any of the portable access rights keys of that PP.
The IPUI is used to identify the portable in the domain defined by its related ARI. The IPUI can either be locally unique
or globally unique.
Figure 4.1 illustrates the identity structure.

The common base for the DECT identity structure is the Access Rights Class (ARC) and Access Rights Details (ARD).
These need to be known by both the FP and the PPs. In the FP the ARC and ARD are called Access Rights
Identity (ARI), and in the PP they are called Portable Access Rights Key (PARK). The distinction between PARK and
ARI is that each PARK can have a group of ARDs allocated, PARK{y}. "y" is the value of the PARK length indicator
given in the PP subscription process.
ARD
ARC

Figure 4.2: Structure of PARK{y}
If the ARI is a primary ARI, i.e. PARI, it will form, together with a RFP number, the broadcast identity RFPI. ARIs can
also be less frequently broadcast as Secondary Access Rights Identities (SARIs) and may also be available as Tertiary
Access Rights Identities (TARIs), which are not broadcast, but are accessible upon request.
The PUT and PUN form the PP user's identity, IPUI. This identity can either be globally unique or locally unique. In
addition to IPUIs, shorter temporary identities, TPUIs, may be used for paging.
A PP is identified by its pairs of PARK{y} and IPUI. A PP is only allowed to access a FP if one of its PARKs includes
one of the ARIs of the FP, i.e. the PARI, a SARI or a TARI.
4.1 Combinations of ARIs, PARKs and IPUIs
DECT provides a flexible radio access technology for a large variety of private and public networks or systems. This
leads to different requirements on e.g. sub-system grouping, distribution and installation of equipment, identity
allocations and subscription.
Therefore five access rights classes A to E and a number of IPUIs have been defined to meet the need for a
differentiation in the identity structures.
Table 4.1 gives an overview of likely combinations of the main identities. As described in clause 6.2 some flexibility is
allowed in combinations of the IPUI types, e.g. IPUI type N could be used by a service provider in combination with
any ARC.

5 FP identities
5.0 General
FP identities are used to inform PPs about the identity of a DECT FP and the access rights to that DECT FP and thereby
reduce the number of access attempts from unauthorized portables.
A DECT FP broadcasts this information on the N -channel via all its Radio FPs (RFPs), at least once per multiframe. A
T
PP needs to be able to interpret necessary parts of this broadcast information to detect the access rights to a system or
even access rights agreements between system operators, i.e. operators A and B have a bilateral agreement permitting
their users to roam between their systems. These agreements can change and cannot therefore be stored in PPs without
updating them frequently. Therefore the FP handles access rights information which is embedded in the identity
structure.
The DECT identity structure provides solutions for residential, public and private environments. This can also be
extended to combinations between these environments, e.g. private groups of users within a public DECT network, and
e.g. public users' access to private DECT networks.
The base for the identity structure is formed by the ARCs and the ARDs:
ARC: Shows the type of access to a DECT network, such as public, private or residential.
ARD: This number is unique to the service provider or to the equipment (e.g. in the case of residential and
business applications this number is assigned by the manufacturer). Its structure depends on the ARC.
The ARC and ARD together form the basic identity, the ARI:
ARI: This identity is globally unique to a service provider, and shows the access rights related to this service
provider. This identity may be applied to any number of FP installations. There are three categories of
ARIs.
PARI: Primary ARI has to be broadcast. This is also the most frequently broadcast ARI in order to give a higher
grade of service to users with these access rights. The PARI is broadcast over the N -channel (see note).
T
The PARI (in conjunction with RPN) also carries information about domains of handover and location
areas.
SARI: Secondary ARI. SARIs are less frequently broadcast than PARIs. They are sent as a SARI-list on the
Q -channel. The message used for SARIs (there could be more than one SARI) is described in clause 5.6.
T
TARI: Tertiary ARI. The TARI is not broadcast at all and is only available as a (or in a) "TARI reply" message,
which is an answer to a "TARI request" message including the relevant PARK{y}. See clause 5.6.6 and
ETSI EN 300 175-3 [3], clauses 7.2.5.10 and 7.3.5.2.
NOTE: Several FPs may apply the same ARI. However, as a PARI it has to be geographically unique.
The classification of primary, secondary and tertiary access rights gives the possibility for operators or system owners
to offer their subscribers/users an almost unlimited list of roaming agreements. This classification can be seen as an
iceberg with the PARI visible on the top followed by a less visible SARI list and in the depth the invisible TARIs. The
PP procedure for handling PARIs, SARIs and TARIs is described in clause 8.2.
Structure of ARI, see figure 5.1.

12 ETSI EN 300 175-6 V2.6.1 (2015-07)
The RFPI has three purposes:
• to carry the PARI;
• to uniquely identify RFPs geographically;
• to show domains for handover and location areas.
The RFPI is frequently transmitted as bits a8 to a47 in the A-field using the N -channel and has therefore a limitation of
T
40 bits. See ETSI EN 300 175-3 [3], clause 7.2.2.

E: This field indicates if there are any SARIs available. Value yes or no.
RPN: Radio fixed Part Number used for geographical separation.
Handover domains:
For DECT two handover domains are defined: internal handover (bearer and connection handover) to be within a FP,
and external handover to be between FPs. Internal handover is possible between RFPs that have the same PARI in their
RFPIs, i.e. only have changes in the RPN. See figure 5.3.

E PARI RPN
External Internal
handover domain handover domain
Figure 5.3: Indication of handover domains
The connection handover domain is always identical to the internal handover domain. The cluster size defines the
bearer handover domain. A PP regards the cluster size as identical with the internal handover domain, if not else has
been indicated by the optional PT "Bearer handover information", see ETSI EN 300 175-3 [3], clause 7.2.4.3.7. The
RFPI for access rights classes A and C is also used for limited information on handover domains, see clauses 5.1
and 5.3.
External handover provision (by the external network) is indicated using the message defined in ETSI
EN 300 175-3 [3], clause 7.2.3.4.2 with the coding defined in ETSI EN 300 175-5 [5], annex F. A PP can request the FP
for information on PARIs of close by FPs to which external handover is supported, see ETSI EN 300 175-5 [5],
clause 15.7. The information also indicates for each FP if it is synchronized to their own system or not.
External h/o length indicator:
The external handover length indicator is defined as the x bits of the PARI part of the RFPI, see figure 5.4. The PP is
allowed to make an external handover based upon the <> to FPs with all of the x bits the
same.

Location Areas (LAs):
A Location Area (LA) is defined as x bits of the PARI plus RPN part of the RFPI, see figures 5.5 and 5.6. As soon as
any of these x bits change the PP has entered into a new LA and should do a location update. The x bits are indicated by
the Location Area Level (LAL) indicator.
Location area with LAL = x bits:

Default location area:

Figure 5.6: Default location area
LAL is submitted to a PP as a result of a successful location registration. See ETSI EN 300 175-5 [5]. The PP uses the
default location area in the absence of a LAL.
A location registration at a FP can be permanent or temporary. If the location registration indicates "temporary user
limit" all location registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to
receive the PARI) for more than T601 min. If the location registration indicates "temporary user limit 2" all location
registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to receive the PARI) for
more than T603 seconds. See clause 6.3.
Four different ARCs have been defined. The structure and layout of ARIs and RFPIs related to these groups are
described in the following clauses.
5.1 ARI class A
This class is intended to be used for small residential and private (PBX) single cell FPs and small multi-cell FPs with a
maximum of 7 RFPs. Equipment belonging to this class will probably be sold by non-expert retailers. Therefore the
allocation process of class details needs to be delegated to manufacturers by a common administration.

EMC: Equipment Manufacturer's Code is allocated to each manufacturer by ETSI or by a provider authorized by
ETSI. Upper limit of EMC is 65 535. EMC = 0 shall not be used. The reason why the EMC has 16 bits is
to avoid small manufacturers contending with a long number series. Larger manufacturers could have
more than one EMC allocated.
ETSI
14 ETSI EN 300 175-6 V2.6.1 (2015-07)
FPN: Fixed Part Number shall be allocated by the manufacturer as a unique number for each EMC. It has an
upper limit of 131 071, which gives a total of over 8,5 billion globally unique ARIs. FPN = 0 shall not be
used.
RPN: Radio fixed Part Number, this number is allocated by the manufacturer/installer and is used to separate a
maximum of 7 different cells from each other. In case of single cell FPs, RPN = 0. This indicates for a PP
that this FP does not have intercell handover, since there is only one RFP.
This class provides enough FP identities for single cell FPs and small multi cell FPs. This results in a longer ARI than
for all other classes. This ARI is therefore restricted only to be used as a PARI and not as SARI or TARI, see clause 5.6.
The class A DECT FP identity is the ARI part of the RFPI and it shall be globally unique.
NOTE: When adding a WRS to a residential single cell system, the RPN of the FT should change from 0 to a
value in range 1 to 7. If the change is not performed, PPs may consider the FT to be a single cell system
and not initiate handover to the WRS.
5.2 ARI class B
This access rights class is reserved for more complex private installations such as LANs and various types of multi-cell
PABXs. In these environments it is necessary to be able to install new, or replace old, equipment without changing
ARIs or RFPIs. This indicates that ARI B is mainly a system identity that follows a system and not a specific
equipment.
The RFPIs could be allocated directly by the manufacturer, or by dealers, or installers authorized by the manufacturer.
The manufacturer is responsible for distributing ARIs to authorized dealers/installers.

EIC: Equipment Installer's Code is allocated by ETSI to each manufacturer, or by a provider authorized by
ETSI. Large manufacturers could have more than one EIC allocated. The same can also apply for users,
i.e. big companies can have their own EIC codes to be used at their different sites. Upper limit of EIC is
65 535. EIC = 0 shall not be used.
FPN: Fixed Part Number is distributed together with the EIC by the manufacturer to authorized installers.
Upper limit of FPN in example shown in figure 5.8 is nominally 255. The value FPN + PS = 0 shall not
be used as a part of the RFPI.
FPS: Fixed Part Sub-number is allocated by the system operator or installer. There are nominally 15 numbers
available, FPS = 0 is reserved for future use, and shall not be used as a part of the RFPI.
A PP may be given access rights to all FPs with the same FPN, by use of a PARK{y}, where y includes only the FPN,
see clause 6. The border between FPN and FPS bits may vary, but the sum shall be 12 bits, and FPN + FPS shall be
unique for each EIC.
RPN: Radio fixed Part Number, is allocated by the operator or installer from the range 0 to 255. The number of
RFPs per system can be larger than 256 through geographical separation.
The class B DECT FP identity is the ARI part of the RFPI. In most cases, the ARI is globally unique. Within the
domain of a network of FPs controlled by one owner/operator, ARIs do not need to be globally unique, but shall be
geographically unique, to avoid ambiguity at call set-up and handover.

POC: Public Operator Code, is allocated by ETSI, authorized by ETSI, or by a provider authorized by ETSI and
is assigned to each operator as single codes or, if necessary, in blocks. The upper limit is 65 535. POC = 0
shall not be used. The operator shall provide a means for a PP user to discriminate between a mobile and
a fixed FP, using the "non-static FP" broadcast attribute.
FPN: Is assigned by the FP operator and can be used to define different areas of subscription. Upper limit of
FPN in example shown in figure 5.9 is nominally 255. The value FPN + FPS = 0 shall not be used as a
part of the RFPI. FPNs can be chosen so that a wanted group of subscription areas is accessed by a PP by
one PARK{y}, see clause 6.
FPS: Is allocated by the FP system operator or installer. FPS = 0 shall not be used as a part of the RFPI. There
are nominally 15 numbers available per subscription area, FPN, for geographical separation of multiple
cell FPs. See below on RPN for single cell FPs.
RPN: Is allocated by the operator/installer. Single cell RFPIs have the least significant bit = 0, which is used to
indicate that intercell handover does not exist in this FP. This gives nominally 15 × 128 single cell RFPIs
for geographical separation per subscription area. Multiple cell RFPIs have the least significant bit = 1.
The number of RFPs per FP can be larger than 128 through geographical separation.
The border between FPN and FPS may vary, but the sum shall be 12 bits. If, for example, 31 FPS are wanted for
geographical separation of multi cell FPs in a subscription area, a 7 bit FPN is used.
The class C DECT FP identity is the ARI part of the RFPI. Note that the PARK, clause 6.1.

1 Scope
The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
This part specifies the identities and addressing structure of the Digital Enhanced Cordless Telecommunications
(DECT) Common Interface (CI).
There are four categories of identities to be used for identification and addressing in a general DECT environment.
These four categories are:
• Fixed Part (FP) identities;
• Portable Part (PP) identities;
• connection-related identities;
• equipment-related identities.
Fixed part identities and portable part identities are used for:
• access information from fixed parts to portable parts;
• access requests from portable parts;
• identification of portable parts;
• identification of fixed parts and radio fixed parts;
• paging;
• billing.
These identities support:
• different environments, such as residential, public or private;
• supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of
central administration;
• multiple access rights for the same portable;
• large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate
provision of access rights to groups of DECT systems;
• roaming agreements between DECT networks run by the same or different owners/operators;
• indication of handover domains;
• indication of location areas, i.e. paging area;
• indication of subscription areas of a public service.
The present document also provides for length indicators and other messages that can override the default location
and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used for
peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency
call set-up.
Coding of identity information elements for higher layer messages is found in ETSI EN 300 175-5 [5], clause 7.7.
ETSI
7 ETSI EN 300 175-6 V2.6.1 (2015-07)
User authentication and ciphering need additional key information and is outside the scope of the present document, but
is covered in other parts of ETSI EN 300 175 [1] to [8], e.g. ETSI EN 300 175-7 [7].
The present document includes New Generation DECT, a further development of the DECT standard introducing
wideband speech, improved data services, new slot types and other technical enhancements.

4 General description of FP and PP identities
4.0 Overview
Every radio FP broadcasts for its purpose a unique identity which contains a globally unique (to a service provider)
Access Rights Identity (ARI). Every PP has both a Portable Access Rights Key (PARK) and an International Portable
User Identity (IPUI). These operate as a pair. A PP is allowed to access any radio FP which broadcasts an ARI that can
be identified by any of the portable access rights keys of that PP.
The IPUI is used to identify the portable in the domain defined by its related ARI. The IPUI can either be locally unique
or globally unique.
Figure 4.1 illustrates the identity structure.

The common base for the DECT identity structure is the Access Rights Class (ARC) and Access Rights Details (ARD).
These need to be known by both the FP and the PPs. In the FP the ARC and ARD are called Access Rights
Identity (ARI), and in the PP they are called Portable Access Rights Key (PARK). The distinction between PARK and
ARI is that each PARK can have a group of ARDs allocated, PARK{y}. "y" is the value of the PARK length indicator
given in the PP subscription process.
ARD
ARC
"don't care" bits

Figure 4.2: Structure of PARK{y}
If the ARI is a primary ARI, i.e. PARI, it will form, together with a RFP number, the broadcast identity RFPI. ARIs can
also be less frequently broadcast as Secondary Access Rights Identities (SARIs) and may also be available as Tertiary
Access Rights Identities (TARIs), which are not broadcast, but are accessible upon request.
The PUT and PUN form the PP user's identity, IPUI. This identity can either be globally unique or locally unique. In
addition to IPUIs, shorter temporary identities, TPUIs, may be used for paging.
A PP is identified by its pairs of PARK{y} and IPUI. A PP is only allowed to access a FP if one of its PARKs includes
one of the ARIs of the FP, i.e. the PARI, a SARI or a TARI.
4.1 Combinations of ARIs, PARKs and IPUIs
DECT provides a flexible radio access technology for a large variety of private and public networks or systems. This
leads to different requirements on e.g. sub-system grouping, distribution and installation of equipment, identity
allocations and subscription.
Therefore five access rights classes A to E and a number of IPUIs have been defined to meet the need for a
differentiation in the identity structures.
Table 4.1 gives an overview of likely combinations of the main identities. As described in clause 6.2 some flexibility is
allowed in combinations of the IPUI types, e.g. IPUI type N could be used by a service provider in combination with
any ARC.

5 FP identities
5.0 General
FP identities are used to inform PPs about the identity of a DECT FP and the access rights to that DECT FP and thereby
reduce the number of access attempts from unauthorized portables.
A DECT FP broadcasts this information on the N -channel via all its Radio FPs (RFPs), at least once per multiframe. A
T
PP needs to be able to interpret necessary parts of this broadcast information to detect the access rights to a system or
even access rights agreements between system operators, i.e. operators A and B have a bilateral agreement permitting
their users to roam between their systems. These agreements can change and cannot therefore be stored in PPs without
updating them frequently. Therefore the FP handles access rights information which is embedded in the identity
structure.
The DECT identity structure provides solutions for residential, public and private environments. This can also be
extended to combinations between these environments, e.g. private groups of users within a public DECT network, and
e.g. public users' access to private DECT networks.
The base for the identity structure is formed by the ARCs and the ARDs:
ARC: Shows the type of access to a DECT network, such as public, private or residential.
ARD: This number is unique to the service provider or to the equipment (e.g. in the case of residential and
business applications this number is assigned by the manufacturer). Its structure depends on the ARC.
The ARC and ARD together form the basic identity, the ARI:
ARI: This identity is globally unique to a service provider, and shows the access rights related to this service
provider. This identity may be applied to any number of FP installations. There are three categories of
ARIs.
PARI: Primary ARI has to be broadcast. This is also the most frequently broadcast ARI in order to give a higher
grade of service to users with these access rights. The PARI is broadcast over the N -channel (see note).
T
The PARI (in conjunction with RPN) also carries information about domains of handover and location
areas.
SARI: Secondary ARI. SARIs are less frequently broadcast than PARIs. They are sent as a SARI-list on the
Q -channel. The message used for SARIs (there could be more than one SARI) is described in clause 5.6.
T
TARI: Tertiary ARI. The TARI is not broadcast at all and is only available as a (or in a) "TARI reply" message,
which is an answer to a "TARI request" message including the relevant PARK{y}. See clause 5.6.6 and
ETSI EN 300 175-3 [3], clauses 7.2.5.10 and 7.3.5.2.
NOTE: Several FPs may apply the same ARI. However, as a PARI it has to be geographically unique.
The classification of primary, secondary and tertiary access rights gives the possibility for operators or system owners
to offer their subscribers/users an almost unlimited list of roaming agreements. This classification can be seen as an
iceberg with the PARI visible on the top followed by a less visible SARI list and in the depth the invisible TARIs. The
PP procedure for handling PARIs, SARIs and TARIs is described in clause 8.2.
Structure of ARI, see figure 5.1.

ARC: 8 available classes named A - H. Only classes A - E are currently defined.

ETSI
12 ETSI EN 300 175-6 V2.6.1 (2015-07)
The RFPI has three purposes:
• to carry the PARI;
• to uniquely identify RFPs geographically;
• to show domains for handover and location areas.
The RFPI is frequently transmitted as bits a8 to a47 in the A-field using the N -channel and has therefore a limitation of
T
40 bits. See ETSI EN 300 175-3 [3], clause 7.2.2.

RPN: Radio fixed Part Number used for geographical separation.
Handover domains:
For DECT two handover domains are defined: internal handover (bearer and connection handover) to be within a FP,
and external handover to be between FPs. Internal handover is possible between RFPs that have the same PARI in their
RFPIs, i.e. only have changes in the RPN. See figure 5.3.

E PARI RPN
External Internal
handover domain handover domain
Figure 5.3: Indication of handover domains
The connection handover domain is always identical to the internal handover domain. The cluster size defines the
bearer handover domain. A PP regards the cluster size as identical with the internal handover domain, if not else has
been indicated by the optional PT "Bearer handover information", see ETSI EN 300 175-3 [3], clause 7.2.4.3.7. The
RFPI for access rights classes A and C is also used for limited information on handover domains, see clauses 5.1
and 5.3.
External handover provision (by the external network) is indicated using the message defined in ETSI
EN 300 175-3 [3], clause 7.2.3.4.2 with the coding defined in ETSI EN 300 175-5 [5], annex F. A PP can request the FP
for information on PARIs of close by FPs to which external handover is supported, see ETSI EN 300 175-5 [5],
clause 15.7. The information also indicates for each FP if it is synchronized to their own system or not.
External h/o length indicator:
The external handover length indicator is defined as the x bits of the PARI part of the RFPI, see figure 5.4. The PP is
allowed to make an external handover based upon the <> to FPs with all of the x bits the
same.

Location Areas (LAs):
A Location Area (LA) is defined as x bits of the PARI plus RPN part of the RFPI, see figures 5.5 and 5.6. As soon as
any of these x bits change the PP has entered into a new LA and should do a location update. The x bits are indicated by
the Location Area Level (LAL) indicator.
Location area with LAL = x bits:

Location Area = x bits of PARI and RPN
Figure 5.5: Location area with LAL = x bits
Default location area:
RFPI

Figure 5.6: Default location area
LAL is submitted to a PP as a result of a successful location registration. See ETSI EN 300 175-5 [5]. The PP uses the
default location area in the absence of a LAL.
A location registration at a FP can be permanent or temporary. If the location registration indicates "temporary user
limit" all location registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to
receive the PARI) for more than T601 min. If the location registration indicates "temporary user limit 2" all location
registration data shall be cleared from a PP if the PP leaves the locked state with that FP (fails to receive the PARI) for
more than T603 seconds. See clause 6.3.
Four different ARCs have been defined. The structure and layout of ARIs and RFPIs related to these groups are
described in the following clauses.
5.1 ARI class A
This class is intended to be used for small residential and private (PBX) single cell FPs and small multi-cell FPs with a
maximum of 7 RFPs. Equipment belonging to this class will probably be sold by non-expert retailers. Therefore the
allocation process of class details needs to be delegated to manufacturers by a common administration.

EMC: Equipment Manufacturer's Code is allocated to each manufacturer by ETSI or by a provider authorized by
ETSI. Upper limit of EMC is 65 535. EMC = 0 shall not be used. The reason why the EMC has 16 bits is
to avoid small manufacturers contending with a long number series. Larger manufacturers could have
more than one EMC allocated.
ETSI
14 ETSI EN 300 175-6 V2.6.1 (2015-07)
FPN: Fixed Part Number shall be allocated by the manufacturer as a unique number for each EMC. It has an
upper limit of 131 071, which gives a total of over 8,5 billion globally unique ARIs. FPN = 0 shall not be
used.
RPN: Radio fixed Part Number, this number is allocated by the manufacturer/installer and is used to separate a
maximum of 7 different cells from each other. In case of single cell FPs, RPN = 0. This indicates for a PP
that this FP does not have intercell handover, since there is only one RFP.
This class provides enough FP identities for single cell FPs and small multi cell FPs. This results in a longer ARI than
for all other classes. This ARI is therefore restricted only to be used as a PARI and not as SARI or TARI, see clause 5.6.
The class A DECT FP identity is the ARI part of the RFPI and it shall be globally unique.
NOTE: When adding a WRS to a residential single cell system, the RPN of the FT should change from 0 to a
value in range 1 to 7. If the change is not performed, PPs may consider the FT to be a single cell system
and not initiate handover to the WRS.
5.2 ARI class B
This access rights class is reserved for more complex private installations such as LANs and various types of multi-cell
PABXs. In these environments it is necessary to be able to install new, or replace old, equipment without changing
ARIs or RFPIs. This indicates that ARI B is mainly a system identity that follows a system and not a specific
equipment.
The RFPIs could be allocated directly by the manufacturer, or by dealers, or installers authorized by the manufacturer.
The manufacturer is responsible for distributing ARIs to authorized dealers/installers.

EIC: Equipment Installer's Code is allocated by ETSI to each manufacturer, or by a provider authorized by
ETSI. Large manufacturers could have more than one EIC allocated. The same can also apply for users,
i.e. big companies can have their own EIC codes to be used at their different sites. Upper limit of EIC is
65 535. EIC = 0 shall not be used.
FPN: Fixed Part Number is distributed together with the EIC by the manufacturer to authorized installers.
Upper limit of FPN in example shown in figure 5.8 is nominally 255. The value FPN + PS = 0 shall not
be used as a part of the RFPI.
FPS: Fixed Part Sub-number is allocated by the system operator or installer. There are nominally 15 numbers
available, FPS = 0 is reserved for future use, and shall not be used as a part of the RFPI.
A PP may be given access rights to all FPs with the same FPN, by use of a PARK{y}, where y includes only the FPN,
see clause 6. The border between FPN and FPS bits may vary, but the sum shall be 12 bits, and FPN + FPS shall be
unique for each EIC.
RPN: Radio fixed Part Number, is allocated by the operator or installer from the range 0 to 255. The number of
RFPs per system can be larger than 256 through geographical separation.
The class B DECT FP identity is the ARI part of the RFPI. In most cases, the ARI is globally unique. Within the
domain of a network of FPs controlled by one owner/operator, ARIs do not need to be globally unique, but shall be
geographically unique, to avoid ambiguity at call set-up and handover.
