are assigned to all the parameters in
the desired groups.

selection.
10 After completing the configuration
actions, you can use steps 1, 2 to
return to the ALARM BUFFER. If alarm
messages are stored in the alarm buffer,
ALARM BUFFER is automatically
displayed if no push-button is pressed
for one minute.

Configuring the System Parameters
For a list of the system parameters, refer to Appendix E, Configuration Parameters.
Remember that even if downloading is enabled, you must locally configure the
CLK_MASTER and CLK_FBACK parameters on both the local and the remote
MX-2100 units if the installed main link interface module is KML.1, KML.2, KML.3
or KML.4 (these parameters are not available for KML.5).
• CLK_MASTER - Select the appropriate source: INT or an external timing
reference source, connected to one of the channels of a KLS.1, KHS.1,
KVF.4/S0, KHS.U/S, KHS.U/D, KVF.5/E1/M, or KVF.5/T1/M module. In this
case, you must select the CLOCK MODE of this channel as DTE2 (otherwise,
you will see CONFIG ERROR 01).
• CLK_FBACK - Select NONE or a source different from that selected as master.
If you select as external source a channel that is not configured for operation in
the DTE2 mode, you will see CONFIG ERROR 02.
• To disable switching to the fallback source, select NONE.
In this case, the default fallback clock source is the MX-2100 internal clock
oscillator.
• DWLD_BW_A, DWLD_BW_B - Select the desired mode: NO to disable the
management channel, or enable the management channel by selecting a
specific value in the range of 0.8 through 19.2 kbps and an EXT to indicate if
the ML-7 or ML-8 is a dedicated time slot or time slot 0.
• These parameters must be set in order to allow in-band configuration of a
remote MX-2100. For more information about in-band communication, refer
to the Remote Management section in the General Information chapter.
When selecting a speed for the download parameter, consider the MX-2100 link's
total bandwidth. Since the bandwidth is shared, make sure that the speed chosen
for the download parameter is high enough to allow the link to work efficiently, but
enough bandwidth is left for data transfer.
