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.
