Installing Voice Cards

Connecting a CVM to an E1 Line or a Subrate Trunk

Channelized voice or data connections on an E1 line use the CVM front card and the BC-E1 back card. Subrate E1 connections use the CVM front card and the BC-SR back card. The E1 trunk interface card BC-E1 contains the E1 connector (G.703 Input/Output) that resides at the top of the back card. The BC-E1 faceplate has four, 75-ohm BNCs.

Note The BC-E1 faceplate provides two connector arrangements for attaching E1 lines. Use either the two BNC (RX and TX) connectors or the 15-pin DB connector.

Make the E1 connections as follows:

Step 1 Bring each E1 BNC patch cable (or 15-pin cable) through the opening at the bottom of the cabinet (if applicable) and up the back of the unit.

Note Some versions of the BC-E1 use a metal BNC connector instead of a plastic BNC. For terminating 75- or 120-ohm balanced E1 lines to the metal BNC connectors on these back cards, remove and discard the BNC mounting nuts. With the mounting nuts removed, the ground that normally appears on one side of the connector shell is also removed. This step is not required for DB-15 connectors or for back cards that use the plastic BNC connectors.

Step 2 Attach the cabling to connectors on the BC-E1s that mate with the CVM (not an NTM).

Step 3 Use the cable management feature to help route the cables.

The back slot line numbers correspond to the back slot number in which the BC-E1 card resides. Record the back slot number of each line. These number are necessary for configuring the system after installation is complete.

The next section describes a specialized version of data transmission service called TDM Transport. It applies to older, non-Cisco WANs.

TDM Transport on the CVM

This section describes how to plan for use of the Time Division Multiplexing Transport (TDM Transport) feature. Note that TDM Transport requires Rev. C firmware on all connected CVMs or CDPs that use this feature. Refer to the TDM Transport description in the Cisco IGX Reference for details on Rev. C firmware features and limitations. Refer to the Cisco WAN Switching Command Reference for a description of the command parameters in related commands.

Before adding a bundled connection under TDM Transport, consider the following:

•If a connection uses a T1 trunk, use cnftrk to configure the line coding for B8ZS instead of ZCS.

•Add the least number of bundled connections to create the data channels.

•The longest delay for a connection determines the end-to-end delay for the entire transparent circuit through the network.

•The Maximum Network Delay is the sum of maximum queuing delays for the trunk cards over which an individual connection is routed. The Maximum Network Delay for a high-speed data connection is 45 ms. Specify this limit using the cnfsysparm command.
