Clear Channel 6-Port T3 (DS3) Line Card Installation and Configuration

Chapter 1 Overview
T3 SMB Cables
After you connect the cables to a configured port on the line card, it takes up to 35 seconds to initialize
the line card and light the green LNK LED.
Ordering Cables
You must order cables separately with the 6T3 line card when you order a Cisco 7304 router. Cables are
not automatically included with the 6T3 line card. Be sure to specify the type of cable you want shipped
with your card (2CBLE-SMB-BNC-M [male] or 2CBLE-SMB-BNC-F [female]).
Building Your Own Cables
You can build your own cables for the 6T3 line card by using the cable components listed in Table 1-3.
All three cables have an SMB connector at one end to connect to the 6T3 line card. The two
SMB-to-BNC cables in Table 1-3 differ only in that one terminates in a male BNC connector, while the
other terminates in a female BNC connector. You can use the back-to-back cable for directly connecting
two closely-spaced 6T3 line cards back-to-back. These cables should be shielded and have SMB
connectors on both ends.
Note Back-to-back configurations, (6T3 line card serial-to-6T3 line card serial port
configurations) require a specially built SMB-to-SMB cable. Table 1-3 provides cable
connector specifications. Or you can use the 2CBLE-SMB-BNC-M 10-foot (3.048 meters)
shielded cable and the 2CBLE-SMB-BNC-F 10-foot (3.048 meters) shielded cable
connected together.
You can order the SMB-to-BNC cables from Cisco as product numbers 2CBLE-SMB-BNC-F (female)
or 2CBLE-SMB-BNC-M (male) BNC terminations, respectively. Cisco does not sell the SMB-to-SMB
cable.
