Connect the E3 Ports
The E3 port supports full-duplex operation
at E3 (34-Mbps) speeds. Use a 75-ohm
coaxial cable to connect to an E3 serial
network. Serial cables conform to
EIA/TIA-612 and EIA/TIA-613
specifications. The E3 serial ports on the
router are considered to be DTE devices.
Note: The E3 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.
Note: The E3 coaxial cable comes with an
attached ferrite bead.
