COMSPHERE 3600 Series Data Service Units
5-34 March 1999 3610-A2-GB41-60
Figure 5-13 maps mode of operation to the applicable
Configuration Option Tables (refer to Chapter 6 of the
COMSPHERE 3600 Series Data Service Units,
Models 3610 and 3611, Operator’s Guide for these
tables). These tables are arranged by option set and
presented in menu tree order. They describe the function
or purpose of each configuration option in the set and
describe each possible selection.
NOTE
Configuration Option Worksheets
in Appendix B summarize the
configuration options in each
option set by mode of operation.
You may want to record
configuration option selections on
one of these worksheets.
In TDM mode, the DSU performs several verification
checks like verifying that the sum of the port speeds does
not exceed the DDS or backup line speed (line speeds are
set in the DSU and DBM submenus; primary and backup
port speeds are set in the PrtSp submenu). The DSU will
not save configuration option selections if there is a
mismatch in option settings. Refer to the COMSPHERE
3600 Series Data Service Units, Models 3610 and 3611,
Operator’s Guide for a list of TDM or MCMP error
messages, what they mean, and how they can be
corrected.
When choosing TDM, MCMP, or Bridge mode, you
are presented with the configuration options listed in
Table 5-9. In this table, the configuration options with an
X for a particular mode are valid for the mode selected. A
configuration option without an X either does not appear
in that mode, is forced to a certain value, or has no
meaning for that mode. For an option forced to a certain
value, all of the values normally available to that option
still appear, but changes made have no effect; the
configuration option’s value is not overwritten in
software.
For a bridge configuration consisting of a central-site
bridge and one or more extended bridges, digital bridge
configuration options must be set for each DSU in the
bridge. Address each of the DSUs through the DCP and
set the configuration options.
