The present document 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
EN 300 324-1 [3] and EN 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 the present document.
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 the present
document, 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 the present document.
The present document 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 the present document.
Existing protocols are used where possible, and the focus of the present document 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 the present document. It is included in the specification relating to fault and
performance management, EN 300 378-1 [6].
