Introduction
V5 interfaces, as described in ETS 300 324 (1994) and ETS 300 347 (1994), operate between an
exchange and an Access Network (AN) to support various narrowband services. These interfaces and their
associated user ports have to be managed by the Operations Systems (OSs) within the
Telecommunications Management Network (TMN).
ITU-T Recommendation G.803 (1993) provides an abstracted view of telecommunications equipment,
based on the essential functions that such equipment needs to perform. These functional components are
modelled by objects, which represent the implementation-independent aspects of the equipment.
The following assumptions relating to the scope of this ETS were to be considered:
- existing protocols should be used where possible, and the focus of the ETS should be on defining
the object models;
- the interface should not involve objects specific to the control of a leased line network which is not
connected to the LE or of an external line test system;
- a model of the AN appears necessary. The model relevant to the present standards on the V5
interface and ports will be developed if it does not already exist elsewhere. Other object models
outside the scope of this ETS may share the same physical Q3 interface;
- the definition of OS functionality is outside the scope of this ETS;
- security management is excluded from this ETS, but aspects of security relating to configuration
management are included;

---------------------- Page: 9 ----------------------

SIST ETS 300 376-1:1997
Page 8
ETS 300 376-1: December 1994
- configuration management includes provisioning and the provisioning activity may include testing, but
this testing is not included in this ETS. It will be included in the specification relating to fault and
performance management;
- the specification should cover the provisioning of national variants and type variants of lines. Existing
modelling, such as the customer administration model, should be used for this, if possible;
- the specification should not cover general functions within the AN, such as multiplexing, cross-
connection and transmission functions, unless some aspect impacts the configuration management
of V5 interfaces and related ports;
- configuration management related to redundancy of V5 interfaces is within the scope of this ETS,
both for multiple V5 interfaces and for the individual links within a V5.2 interface;
- the definition of an object model for a transparent channel on the V5 interface which supports the
synchronization of OSs is outside the scope of this ETS;
- it is assumed that the relationship between directory numbers and equipment is kept in the OSs of
the AN, so that the Q3 interface of the AN does not need to handle directory numbers.

1 Scope
This European Telecommunication Standard (ETS) specifies the Q3 interface between an Access Network
(AN) and the Telecommunications Management Network (TMN) for the support of configuration
management functions for V5 interfaces, as described in ETS 300 324-1 [3] and ETS 300 347-1 [4], and
their associated user ports. The management of transmission, media and services which are not related to
V5 interfaces is outside the scope of this ETS.
The Q3 interface is the TMN interface between network elements or Q-adapters which interface to
Operations Systems (OSs) without mediation and between OSs and mediation devices. The location of the
Q3 interface is illustrated in annex G.
Generic modelling of leased line ports which are associated with a V5 interface is within the scope of this
ETS, but the traffic from these ports can only be associated with 64 kbit/s bearer channels on the V5
interface.
The definition of OS functionality, and the specification of Qx interfaces and proprietary interfaces are
outside the scope of this ETS.
This ETS does not constrain the logical or physical size of the AN or its geographical dispersion. The
definition of the managed object class which represents an AN is outside the scope of this ETS.
Existing protocols are used where possible, and the focus of this ETS is on defining the object models.
NOTE: Configuration management includes provisioning and the provisioning activity may
include testing, but this testing is not included in this ETS. It is included in the
specification relating to fault and performance management, ETS 300 378-1 [6].
