MX-2100/2104 Installation and Operation Manual Chapter 1 General Information
Application Considerations 1-17
If you are using automatic frame allocation, special precautions must be taken to
ensure proper operation of the link:
In general, the two MX-2100 units must be identically equipped. Both units must
include the same modules with the following exceptions:
The KLS.1 in the local MX-2100 unit can work with the KLS.2 in the
remote MX-2100 unit.
The KVF.4 in the local MX-2100 unit can work with the KVF.5 in the
remote MX-2100 unit.
The KMBE in the local MX-2100 unit can work with the KHS.2 in the
remote MX-2100 unit.
The KVF.6 in the local MX-2100 unit can work with the KVF.8 in the
remote MX-2100 unit.
The order of the modules must be the same in both units, and their connections to
main link modules must be the same.
The modules and module channels installed in the two MX-2100 units must be
identically configured, except for parameters that control local interfacing
characteristics, such as the channel interface type, the timing modes, etc.
After each change of configuration that affects the bandwidth utilization, e.g.,
addition of a new channel, selection of a mode that requires end-to-end signaling,
etc., perform the REBUILD FRAME command on both MX-2100 units.

The allocation of bandwidth is performed in distinct units. The bandwidth
allocation unit (BAU) is 0.4, 0.8, 1.6, 3.2 or 6.4 kbps, in accordance with the main
link data rate (see Table 1-1).
