Setting Up a UXM-E
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
Step 2
Step 3
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
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 two BNC (RX and TX) connectors or the 15-pin DB connector.
Make the E1 connections as follows:
Step 1
Note
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
Step 3
Record the slot numbers of the NTM/BC-E1 card set. You need these numbers when you configure
the system.

Use the cable management feature to help route the cables.
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.
If the number of trunks is odd, connect as many as possible in pairs, and connect the
