Common Logic Modules
The MX enclosure requires one KCL.2 type common logic module. The main
functions of the KCL.2 module are control of:
•
Multiplexing/demultiplexing operations
•
System management
•
Interfacing with the optional external system management.
The KCL.2 module stores the MX-2100 database in non-volatile memory
(NVRAM). The configuration information stored in the NVRAM is downloaded to
the module installed in MX-2100 upon turn-on or after system reset. Therefore,
during troubleshooting activities, it is possible to temporarily remove the KCL.2
module from the MX-2100 enclosure without disrupting system operation. If it is
necessary to replace the KCL.2 module, the database can be transferred to a new
module by installing the NVRAM taken from the original module in the
replacement module.
Main Link Modules
The enclosure can accept one KML type main link interface module or, for
MX-2100, two KML type main link interface modules. In addition to main link
interfacing, the KML module performs the multiplexing and demultiplexing
functions and provides the timing signals used by the other modules installed in
the enclosure. Two KML modules are necessary for dual link configurations and for
main link redundancy.
The following main link interface modules are available:
KML.1
- V.35 main link interface module
KML.2
- V.24/RS-232 main link interface module
KML.3
- V.36/RS-422/RS-530 main link interface module
KML.4
- X.21 main link interface module
KML.5
- G.703 codirectional main link interface module
KML.6
- Standard DDS CSU/DSU main link interface module
KML.7
- T1 main link interface module
KML.8
- E1 main link interface module.
