Chapter 14 Connecting Cables
Making a BXM T3/E3 Connection
Y-Cabling redundancy is supported on the BXM T3/E3 cards. An example of a Y-cable is shown in
Figure 14-5.
To make a BXM T3/E3 connection:
Step 1 At the back of the cabinet, route each cable up the inside of the cabinet, as applicable. If Y-cables are
used, the Y-cable connects to the corresponding connectors on adjacent cards.
Step 2 The Cisco cabinet has velcro tie-downs inside the cabinet to hold cabling in place. If using a Cisco
cabinet, pull the tie downs apart as applicable, place the routed cable in position, wrap the ties around
the cable and remake the loops by pressing the two sections together.
Step 3 Connect the cables to the applicable connectors on the T3/E3 line modules.
Remember, the RCV is an input to the BPX switch and XMT is an output from the BPX switch. The
ports are numbered from top to bottom.
Step 4 For an open rack configuration in which Y-redundancy is not being used, an optional cable management
tray is available. This is helpful for routing cables when a number of DS3/T3 cards are installed
resulting a large number of cables to handle. Refer to Chapter 12, Installing the T3/E3 Cable
Management Tray.
