7.1.1 XMP1 as network element
Within a TMN, the XMP1 node is considered as network element. Normally,
a network element is composed of several units which can be addressed
individually. It is possible to regard the network element from a logic
functional or an equipment view.
In the QD2 standard, the normal XMP1 network element is addressed as
CCM1/0 (equipment version 40)(1=2 Mbit/s, 0=64kbit/s) representing a
plesiochronous cross-connect multiplexer of hierarchy level 1. When using
a MUX 34 module, it is addressed as CCM3/1/0 (equipment version 41).
An XMP1 with the SDH expansion is treated as a PDH NE with SDH
expansion (equipment version 43).
Equipment view of the XMP1 network element
The equipment with modules indicates the hardware components of a
network element. These components are referred to as plug-in modules.
Logic view of the XMP1 network element
The XMP1 Flexible Multiplexer is divided up into various functional
sub-units, the so-called functional groups (FG). These include SDH
modules, port modules, clock supply, KZU module, data modules etc.. This
permits a hardware-independent view. A higher-order network
management system such as ServiceOn Access "sees" the network
element from this view. The sum of all functional groups forms the functional
model.
All SISA information is managed by the so-called SISA-0.
