7.1.3 Commissioning
The initial commissioning and new commissioning of XMP1 network
expansions of version 5.1 and higher is executed using the SOX MSP. The
commissioning process of the entire network element is performed
according to the operating instructions of the individual modules and
depending on the performance features of the SOX MSP version used.
The Central Units available in the individual nodes receive their
configuration information via the F-interface using a download process
executed by the SOX MSP application. This information is then distributed
to the individual modules in the node. The Q-interface receives the required
information and converts it in compliance with the QD2 standard.
After commissioning, the XMP1 network is controlled, configured and
monitored by the ServiceOn Access Network Management System.
SOX MSP can also be used subsequently to modify or expand the node.
For this purpose, the node configuration data must be read out from node.
After modifying the data these must be downloaded again to the node and
activated in the latter.
Note: Depending on the type of modification, the QD2 section of
the QD2 Central Unit or QD adapter will execute a reset in order
to activate the new configuration. This reset is signalled to the
ServiceOn Access Network Management System. For this
reason, it might be necessary to update open ServiceOn Access
windows.
7.1.4 Functional model
Like every network element, the XMP1 also provides a SISA-0 functionality.
A Plesiochronous Equipment Timing (PET) process is used for clock
recovery. The switching matrix function is provided by a Bottom Path
Connection 64kbit/s (BPX 64). The relevant functional groups are no
separate modules, but only Central Unit functions.
The function groups depicted with a dashed line border in the diagram
below are belonging to the SDH section of XMP1.
These are based on the QD2 information model as per "July 1995". Some
important functional groups are described in the following sections.
