Foreword
This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
In analogy with CCITT Recommendation I.130 (refer to annex A), the first stage of the following three level
structure is used to describe the telecommunications service as provided by European public
telecommunications operators.
- Stage 1: is an overall service description, from the service subscriber's and user's stand-point;
- Stage 2: identifies the functional capabilities and information flows needed to support the service
described in stage 1; and
- Stage 3: defines the signalling system protocols and switching functions needed to implement the
service described in stage 1.
This ETS details the stage 1 aspects (overall service description) for the Universal Access Number (UAN)
service, taking into account the various network architectures, e.g. Intelligent Network (IN).
The application of stage 2 and stage 3 may be different when the service is supported on an IN
environment.
Transposition dates
Date of adoption: 21 February 1997
Date of latest announcement of this ETS (doa): 30 June 1997
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 December 1997
Date of withdrawal of any conflicting National Standard (dow): 31 December 1997

1 Scope
General
This European Telecommunication Standard (ETS) defines the stage 1 for the Universal Access Number
(UAN) service. Stage 1 is an overall service description, primarily from the service subscriber's and user's
point of view, but does not deal with the details of the human interface itself. This ETS includes
information applicable to network operators, service providers and terminal, switch and database
manufactures.
NOTE: In some fora, this service is also referred to as the "shared cost service".
This ETS specifies the requirements where the service is provided to the user via a telecommunications
network that is either the pan-European Integrated Services Digital Network (ISDN) or any other Public
Switched Telephone Network (PSTN) as provided by European public telecommunications operators.
The requirements different from those of the basic call where the UAN service is provided to the user via a
mobile network are outside the scope of this ETS. However, if calls to the UAN service originate or
terminate in a mobile network and any special procedure above those for the basic call has to be
performed, this is be stated in the subclause 7.1 dealing with the interworking between ISDNs, PSTNs and
mobile networks.
This ETS contains the core requirements for the UAN service which are sufficient to provide a complete
service.
This ETS also documents some additional requirements which can be implemented (but do not have to be
implemented).
Furthermore, additional functionalities not documented in this ETS may be implemented. The
requirements of which are considered outside the scope of this ETS and consequently outside the scope
of the corresponding stage 2 and stage 3 standards. This additional functionality may be on a
network-wide basis, or particular to one or a group of users. Such additional functionality shall not
compromise conformance to the core requirements of the service.
Charging principles are outside the scope of this ETS, unless specific service requirements are stated.
These requirements deal with the allocation of certain call charges to particular users.
Interactions with services/supplementary services not listed in clauses 8 and 9 are outside the scope of
this ETS.
Interactions between optional UAN service features and ISDN supplementary services are outside the
scope of this ETS, unless a specific indication is given.
Definition and applicability
The UAN service allows the service subscriber having one or several installations to be reached from all
or part of the network with a unique universal access number. Calls to the universal access number shall
be routed to destinations defined by the service subscriber.
The UAN service is applicable to all telecommunication services using numbers conforming to the
numbering plan and structure specified in CCITT Recommendation E.164 [2].
This ETS is applicable to the stage 2 and stage 3 standards for the UAN service, where the text indicates
the status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, as a
capability or a possibility), this shall be reflected in the relevant stage 2 and stage 3 standards. Otherwise
the status of a requirement shall be reflected in the relevant standards for the underlying protocols.

---------------------- Page: 11 ----------------------

ETS 300 710: March 1997
Furthermore, conformance to this ETS is either met by:
- conforming to the stage 3 standards; or
- implicitly covered by conforming to the standards for the underlying protocols;
with the field of application appropriate to the equipment being implemented. Therefore no method of
testing is provided for this ETS.
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed

service provider.
service subscriber profile: Service subscriber related data needed by the UAN service in order to
handle calls.
service subscriber: Entity which subscribes to the UAN service.
service: That which is offered by a service provider to its customers in order to satisfy a
telecommunication requirement.
universal access number call: A call placed to a universal access number.

5 Description
5.1 Core requirements
The UAN service allows the service subscriber having one or several installations to be reached from all
or part of the network with a unique universal access number. Calls to the universal access number shall
be routed to destinations defined by the service subscriber.
5.2 Optional requirements
5.2.1 General
The optional requirements contain functionalities additional to the core requirements, that customize the
service according to specific service subscriber's needs. These additional parts may be offered either to
all the service provider's customers, or to a group or even to a single customer.
Some possible optional service features are listed hereafter, but the service provider may offer other
additional service features.
In particular the service subscriber may have incoming calls routed to his destination(s) or rejected based
on routing features which may include:
- origin dependent routing;
- time dependent routing (time of day/day of week/date);
- call distribution;
- type of service request (based on e.g. the bearer capability);
- calling line identity.
As a subscription feature, the service subscriber can access for control purposes, with some restrictions,
the network to modify his service profile.
As a service provider option the service subscriber may obtain reports containing statistical information on
incoming universal access number traffic to his destinations, which may include itemized billing.
The service provider may offer other additional service features.
5.2.2 Origin Dependent Control (ODC)
This feature enables the service subscriber to select the origination from which the service may be used.
Such selection may be based for instance:
- on the geographical area the call originates from;
- on the calling line identity, using a screening black list (calls are rejected when calling line identity is
found in the screening list);
- on the calling line identity, using a screening white list (calls are rejected when calling line identity is
not found in the screening list).
5.2.3 Origin Dependent Routing (ODR)
This feature enables the service subscriber to split the service catchment area into different routing areas,
and to specify the routing destination(s) for each of the routing areas. The routing areas may be specified
by the service subscriber.

SIST ETS 300 710 E1:2003
Page 13
ETS 300 710: March 1997
5.2.4 Time Dependent Control (TDC)
This feature enables the service subscriber user to specify time intervals (e.g., time of the day, day of the
week, specific dates), that can be used to modify the handling of the call according to the point in time
when the call is placed. The time interval shall be specified by the service subscriber.
NOTE: Handling of the call may for instance include acceptance or rejection of calls,
percentage of call distribution, number of calls to be queued, number of simultaneous
calls before call limitation.
5.2.5 Time Dependent Routing (TDR)
This feature enables the service subscriber to specify the routing destination(s) according to a selected
time interval. At a given point in time, an originated call shall be routed to the destination as defined for the
time interval in which the given point in time matches.
NOTE: The time interval may for instance take into account day of year, day of week, time of
day.
5.2.6 Call Distribution (CD)
This feature enables the service subscriber to specify distribution mechanisms for universal access
number calls to be shared between different destinations.
NOTE: Distribution mechanisms may be, for example:
- managed accordi
