Overview
The T3 DFC provides physical line termination for a channelized T3 ingress trunk line. It uses an
onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line. (See
Figure
4-1.)
The T3 DFC provides physical line termination for up to 672 DS0 channels and uses onboard
HDLC controllers to terminate digital (ISDN) calls.
You can use the bantam jacks on the DFC to monitor a T1 line or test any one of the individual
T1 circuits in drop and insert mode.
