scope:

This European Telecommunication Standard (ETS) addresses management aspects of the Flexible Multiplexer (FM) equipment. The FM management functions are specified and management network architecture is described.

NOTE: The requirements of Flexible Multiplexer equipment with a variety of access methods for use in synchronous digital leased line networks are defined in part 1 of this ETS (ETS 300 461-1 [31]).

Sub-64 kbit/s signals are not precluded and are considered as an option that may be described according to the methodology used in this ETS. In the same way, special functions such as Adaptive Differential Pulse Code Modulation (ADPCM), conference bridges, etc., which are only mentioned in an annex of part 1 (ETS 300 461-1 [31]), are not considered.

The requirements presented here are limited to the basic functions, external characteristics and performance of the equipment. Some management functions may be implemented in a mediation device which may support both Q protocol adaptation and Operations Systems (OS) functionalities.

Part 1 of this ETS (ETS 300 461-1 [31]) defines functions and indicates whether or not they are mandatory. If supported, a function has to be managed according to this part 2 of this ETS. Part 2 of this ETS specifies when necessary the optional management characteristics (attributes, operations and notifications) of the objects.
