Installing Voice Cards

Step 10 Configure the cellbus bandwidth allocation with cnfbusbw if you plan to activate a large number of ports on the UXM-E. Use dspbusbw or cnfbusbw to check cellbus usage and changes in bandwidth requirements for the UXM-E. For an explanation of cellbus bandwidth allocation, see the Cisco IGX 8400 Series Reference.

Note Cisco recommends that you not allow oversubscription. Refer to the Cisco IGX 8400 Series Reference for the description of cellbus bandwidth allocation and the Cisco WAN Switching SuperUser Command Reference for a description of cnfbusbw. Any user can view the current cellbus bandwidth allocation by using the dspbusbw command.

Step 11 To check the status of the lines, use dsplns.

Step 12 To configure the duration, sample count and size, and peak values for historical port statistics, use cnfportstats. Use dspportstats to display the summary statistics for cell count, CLP cell count, OAM cell count, RM cell count, OAM cell count, unknown VPI/VCI cell count, and optional LMI/ILMI status. Other applicable commands are: dsplnerrs, dspportstatcnf and dspportstathist.

Installing Voice Cards

This section describes how to install the voice cards. See the section titled “IGX Configuration Summary on page 49” for a summary of the commands that apply to circuit lines and voice connections. The two voice card sets are the channelized voice module (CVM) and the universal voice module (UVM). These cards can also carry channelized data. The serial data card sets are the HDM and LDM. This section also describes the considerations for using the TDM Transport feature on the CVM.

Connecting a CVM to a T1 or J1 Line

Voice or data connections on a T1 line use the CVM front card and the BC-T1 back card. Japanese J1 connections use the CVM front card and the BC-J1 back card. The procedure for making J1 connections is the same as for T1 connections. Make the T1 connections as follows:

Step 1 Bring each cable through the opening at the bottom of the cabinet (if applicable) and up the back of the unit.

Step 2 Use the cable management feature to help route the cables.

Step 3 Connect the trunks to the connectors on the BC-T1s that mate with the CVM (not NTM). The T1 lines are attached to DB-15, sub-miniature, 15-pin connectors on the BC-T1 cards.

The back slot line numbers correspond to the back slot number in which the BC-T1 card resides. Record the back slot number of each line. These numbers are necessary for configuring the system after you complete hardware installation.

Note If the number of lines is odd, connect as many as possible in pairs, and connect the remaining lines in ascending order.
