Connect the T3 Ports
The T3 port supports full-duplex operation
at T3 (45-Mbps) speeds. Use a 75-ohm
coaxial cable to connect to a T3 serial
network. Serial cables conform to
EIA/TIA-612 and EIA/TIA-613
specifications. The T3 serial ports on the
router are considered to be DTE devices.
Note: The T3 ports support several types
of integrated DSUs. For a listing of DSU
feature compatibilities, refer to Appendix C,
“Cable Specifications,” in the Cisco 7100
Series VPN Router Installation and
Configuration Guide.
1 Attach the appropriate 75-ohm coaxial
cable directly to the receptacle on the
router and tighten the strain-relief
screws.
2 Attach the network end of the coaxial
cable to the external synchronous serial
equipment.
