7.1.2 Connecting options
For connecting a PDH network element to a network management system,
a Q-interface complying with ITU-T M.3010 is used.
In the XMP1 Flexible Multiplexer, this Q-interface is made available by the
QD2 Central Unit or the QD2 adapter. Due to the data exchange with the
Central Unit functions, the respective QD2 part provides the convertible
information and configuration data at the Q-interface.
An optional Ethernet interface located on the Central Unit permits access to
the network management system over IP.
During the initial commissioning process, the node must be informed on the
SISA-0 address of the QD2 section. This is done using the Local Service
PDA.
Three variants are available for setting up the connection to a higher-order
network management system.
•IP
• RS485 bus
•ECC64
•ECC8
Note: The network element that provides access to SOA must
only be connected with one of the described variants to SOA.
Optionally, the following connection options can be implemented in the
downward hierarchical order by means of the QD2 Master function (with
license):
• RS485 bus
•ECC64
•ECC8
Please note that a connection using this function is possible only if the latter
has not yet been used for the connection setup in the SOA direction.
