Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 1 of a multi-part standard as described below:
Part 1: "Q3 interface specification at the Local Exchange (LE) for fault and performance
management of V5 interfaces and associated customer profiles";
NOTE: A possible further part 2 may contain the Managed Object Conformance Statement
(MOCS) proforma specification.
The following multi-part standards are directly related to this ETS:
ETS 300 376: "Q3 interface at the Access Network (AN) for configuration management of V5 interfaces
and associated user ports";
ETS 300 377: "Q3 interface at the Local Exchange (LE) for configuration management of V5 interfaces
and associated customer profiles";
ETS 300 378: "Q3 interface at the Local Exchange (AN) for fault and performance management of V5
interfaces and associated user ports".
Transposition dates
Date of adoption of this ETS: 17 November 1995
Date of latest announcement of this ETS (doa): 28 February 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 August 1996
Date of withdrawal of any conflicting National Standard (dow): 31 August 1996
Introduction
V5 interfaces, as described in ETS 300 324-1 and ETS 300 347-1, operate between a Local Exchange
(LE) and an Access Network (AN) to support various narrowband Integrated Services Digital Network
(ISDN) and Public Switched Telephone Network (PSTN) services. These interfaces and their associated
user ports need to be managed by the Operations Systems (OSs) within the Telecommunications
Management Network (TMN). This management is performed by means of Q3 interfaces.
The companion standard on configuration management ETS 300 377-1 defines how the Q3 interface of a
LE handles the configuration information for V5 interfaces and their associated customer profiles. This
ETS describes the extension to include fault and performance management.
Fault management of V5 interfaces and associated user ports is part of a management activity which is
performed by the operator in order to detect failure conditions and to bring the customer access back to its
normal state of operation whenever a deviation occurs.
Performance management of V5 interfaces and associated user ports is part of a management activity
which is employed in order to maintain the quality of service levels agreed with the customers. The
activities undertaken in performance management are monitoring, analysis and problem alerting,
diagnosis, optimization and control.
A customer access is considered as being that part of the local network which extends from the network
termination equipment up to and including the exchange termination.

Here, only these parts of the activities are covered which are related directly to a V5 interface between a
LE and an AN or to that part of the customer access which extends from the AN to the network
termination equipment. An ISDN access extends to but does not include the T reference point. An
analogue access extends to and may include the Customer Premise Equipment (CPE) (see figure 1).

NOTE: Shaded areas are subject to V5 fault and performance management. User ports represent the
different configurations for Line Circuit (LC), Line Termination (LT), Exchange Termination (ET)
and Network Termination (NT) as given in figure 2 of the V5 specifications ETS 300 324-1 and
ETS 300 347-1.
Figure 1: Scope of V5 fault and performance management
This ETS details only those functions and management information model components for which V5
specific descriptions are required. However, the use of other components which may be applicable from
other specifications is not precluded. In this case, combined application incorporating both V5-specific and
more generic aspects would result. For example, if log control is to be provided in conjunction with the V5
specific alarm reporting function (see annex A) then other specifications (e.g. CCITT Recommendation
X.735) are available to define this.
The management information model described in this ETS complements that for configuration; both
information models will normally share the same physical interface.

1 Scope
This European Telecommunication Standard (ETS) specifies the Q3 interface between a Local Exchange
(LE) and the Telecommunications Management Network (TMN) for the support of Fault and Performance
Management functions for V5 interfaces, as described in ETS 300 324-1 [2] and ETS 300 347-1 [3], and
their associated customer profiles. The management of transmission, media and services which are not
related to V5 interfaces is outside the scope of this ETS, as is the management of equipment. This ETS
includes the logging of faults and related functions.
For certain implementations, some test related functions like line monitoring, pattern injection for loopback
tests and Dual Tone Multi-Frequency (DTMF) measurements may also be performed in the LE, e.g. due
to economical reasons. A Q interface for these functions is required at the LE. As they are not V5 specific,
this has to be handled within an overall LE test model which is outside the scope of this ETS.
The location of the Q3 interface to which this ETS refers is specified in ETS 300 377-1 [4].
Existing protocols are used where possible, and the focus of the work is on defining the object models.
The definition of Operations System (OS) functionality is outside the scope of this ETS.
