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

featurecompatibilities,refertoAppendixC,
