Installing Voice Cards

•The total delay for a connection is defined as the sum of the propagation and trunk queuing delays. The total delay for a connection cannot be more than 25 ms different from the total delay for any other connection on the same card. The user is responsible for configuring the connections so that no difference between total delays exceeds 25 ms. If the 25 ms is exceeded, an error message is generated in the form CC0700d6, where CC is the slot number.

•In System Software 8.2, add the connection with addcon using 7/8 coding even though the system internally uses 8/8 coding. This causes the system to reserve the additional bandwidth required for the TDM Transport feature.

Connecting a UVM to T1 Lines

Voice or data connections on a T1 line use the UVM front card and the BC-UVI-2T1EC back card. The procedure for connecting the T1 lines is 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. Install optional Y-cables as needed. You can use the cable management feature to help route the cables.

Step 2 If the intended compression for voice channels is LDCELP and the number of channels on a T1 line exceeds 16, install cabling for pass-through. Note that the UVM does not pass-through t-type or td-type connections. For the steps that follow, refer to Figure 3-8for an illustration of the possible UVM cabling arrangements. Note that, in Example B, the number of channels has not exceeded the UVM capacity, so pass-through is unnecessary.

•On port 1 of the primary UVM, connect the cable to the CPE.

•On port 2 of the primary UVM, connect the cable to port 2.

•Connect the cable from port 2 of the primary card to either port 1 or port 2 of the secondary UVM. Typically, if the secondary UVM is supporting the passed-through channels from only one primary UVM, you would connect the cable from port 2 of the primary card to port 1 of the secondary card. However, because the secondary UVM can receive 16 passed-through channels with LDCELP compression, you can pass 8 channels each from other UVMs.

•If the secondary UVM is supporting an additional 8 channels with LDCELP, connect the cable between the port 2 of the secondary UVM and the other primary UVM.

For a description of the pass-through feature, refer to the Cisco IGX 8400 Series Reference.

Record the back slot number and port number of each line. These numbers are necessary for configuring the system after you complete hardware installation.
