ETS 300 376: "Q3 interface at the Access Network (AN) for configuration management of V5 interfaces

ETS 300 379: "Q3 interface at the Local Exchange (LE) for fault and performance management of V5

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 300 376-1 defines how the Q3 interface of

an AN handles the configuration information for V5 interfaces and their associated user ports. This ETS

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

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,

A customer access is considered as being that part of the local network which extends from the network

Here, only these parts of the activities are covered which are related directly to a V5 interface between a
