Connecting an NTM T1 or Y1 Trunk

The T1 trunk connections use the NTM front card and the BC-T1 back card. Japanese Y1 connections use the NTM front card and the BC-Y1 back card. The procedure for making Y1 connections is the same as for T1 connections described below.

Make the T1 connections as follows:

Step 1 Bring each T1 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 are part of NTM/BC-T1 card sets. The T1 lines are attached to DB-15, subminiature, 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 trunks is odd, connect as many as possible in pairs, and connect the remaining lines in ascending order.

Connecting an NTM E1 or Subrate Trunk

The E1 trunk connections use the NTM front card and the BC-E1 back card. Subrate E1 connections use the NTM front card and the BC-SR back card. The E1 trunk interface card BC-E1 contains the E1 trunk connector (G.703 Input/Output) that is located 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 top or bottom of the cabinet (whichever applies) and along 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 at the metal BNC connectors, remove the BNC mounting nuts. This removes the ground that normally appears on one side of the connector shell.

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

Step 3 Connect the cables to connectors on the BC-E1s that are part of an NTM/BC-E1 card sets.

Record the slot numbers of the NTM/BC-E1 card set. You need these numbers when you configure the system.
