Clear Channel 6-Port T3 (DS3) Line Card Installation and Configuration
OL-3449-02
Chapter 1 Overview
T3 SMB Cables
The following conditions must all be met before the 6T3 line card is enabled:
• The 6T3 line card is correctly connected and receiving power.
• The Network Services Engine 100 (NSE-100) recognizes the 6T3 line card.
• The Cisco IOS image on the NSE-100 is running.
If any one of these conditions is not met, or if the initialization fails, the STATUS LED does not go on.
Table 1-2 lists 6T3 line card LED colors and indications.
T3 SMB Cables
The cables used to connect the 6T3 line card are presented in the following sections:
• Ordering Cables, page 1-6
• Building Your Own Cables, page 1-6
We recommend using six T3 SMB cables. The cables are 10 feet (3.048 meters) long and have two
female SMB connectors on one end, and two female or male bayonet coupling (BNC) connectors on the
other end. Use the female SMB cable connectors to connect the local line card RX and TX ports. Use
the BNC cable connectors to connect the line card RX and TX ports to other devices. See
Figure 3-2 .
Note Cisco does not automatically provide the six T3 SMB cables recommended for your 6T3
line card.
