Configuring the DDI Mux module 165
Programming Operations Guide
Assigning lines for voice traffic
A digital T1 line has up to 24 telephone lines available for use. On the DDI Mux, you can assign
some of these lines to telephony traffic and some to data traffic.
For the lines that you want to use for telephony traffic, configure the lines in the same manner as
you configure lines for a DTM. For information about how to configure digital lines on a DTM,
refer to
“Provisioning lines (PRI, T1, DASS2)” on page 152 .
Assigning lines to the data module
The number of lines you assign to the data module determines the bandwidth of your data
networking connection. The following table shows the allocated bandwidth for the DDI Mux
according to the number of lines assigned. The allocated bandwidth also depends on the line data
rate indicated by the B-channel data rate parameter.
To assign a line to the data module, you must change the line type to Fixed Data Channel and then
assign the line to the data module.
Changing the line type
1 In the Unified Manager, click the keys beside Services and Telephony Services .
2
Click the Lines key and then click the Physical lines key.
3 Click the All physical lines key.
4
Click the key of one of the line numbers assigned to the Data Module.
