3 Definitions, conventions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Adjacent SIP Node (ASN): SIP node (e.g. SIP Proxy or Back-to-Back User Agent or the SIP side of an IWU) that has
established a direct trust relation (association) with Incoming or Outgoing IWU entities
NOTE: The SIP Proxy and Back-to-Back User Agent are defined in accordance with IETF RFC 3261 [4].
Basic Call Control (BCC): signalling protocol associated with the DSS1 - ISDN Basic Call control procedures of
ETSI EN 300 403-1 [i.1]
Incoming Interworking Unit (I-IWU): physical entity, (which can be combined with a BICC ISN or ISUP exchange)
that terminates incoming calls using SIP and originates outgoing calls using the BICC or ISUP protocols
incoming or outgoing: direction of a call (not signalling information) with respect to a reference point
incoming SIP or BICC/ISUP (network): network, from which the incoming calls are received, that uses the SIP or
BICC/ISUP protocol (without the term "network", it simply refers to the protocol)
Outgoing Interworking Unit (O-IWU): physical entity, (which can be combined with a BICC ISN or ISUP exchange)
that terminates incoming calls using BICC or ISUP protocols and originates outgoing calls using the SIP
outgoing SIP or BICC/ISUP (network): network, to which the outgoing calls are sent, that uses the SIP or
BICC/ISDN protocol
NOTE: Without the term "network", it simply refers to the protocol.
SIP precondition: mechanism for reserving bearer resources that is required for certain access technologies
NOTE: As defined in IETF RFC 3312 [6].
test purpose: non-formal test description, mainly using text
NOTE: TSIs test description can be used as the basis for a formal test specification (e.g. Abstract Test Suite in
TTCN). See ISO/IEC 9646 [i.2].
3.2 Conventions for representation of SIP/SDP information
1) All letters of SIP method names are in capital.
EXAMPLE 1: INVITE, INFO.
2) SIP header fields are identified by the unabbreviated header field name as defined in the relevant RFC,
including capitalization and enclosed hyphens but excluding the following colon.
EXAMPLE 2: To, From, Call-ID.
3) Where it is necessary to refer with finer granularity to components of a SIP message, the component concerned
is identified by the ABNF rule name used to designate it in the defining RFC (generally 25/IETF
RFC 3261 [4]), in plain text without surrounding angle brackets.
EXAMPLE 3: Request-URI, the user info portion of a sip: URI.
4) URI types are represented by the lower-case type identifier followed by a colon and the abbreviation "URI"
EXAMPLE 4: sip: URI, tel: URI.
5) SIP provisional responses and final responses other than 2XX are represented by the status code followed by
the normal reason phrase for that status code, with initial letters capitalized.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TS 101 585 V2.1.1 (2018-02)
EXAMPLE 5: 100 Trying, 484 Address Incomplete.
6) Because of potential ambiguity within a call flow about which request a 200 OK final response answers, 200
OK is always followed by the method name of the request.
EXAMPLE 6: 200 OK INVITE, 200 OK PRACK.
7) A particular line of an SDP session description is identified by the two initial characters of the line -- that is,
the line type character followed by "="
EXAMPLE 7: m=line, a=line.
8) Where it is necessary to refer with finer granularity to components of a session description, the component
concerned is identified by its rule name in the ABNF description of the SDP line concerned, delimited with
angle brackets.
EXAMPLE 8: The and components of the m= line.
