ÖNORM EN 300379-1 V 1.2.1

The present document 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 EN 300 324-1 [2] and EN 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 the present document, as is the management of equipment. The present document includes the logging of faults and related functions. For certain implementations, some test related functions like line monitoring, pattern injection for loop back 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 the present document. The location of the Q3 interface to which the present document refers is specified in EN 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 the present document.
