Function
For E1 interfaces, configure the
termination to work with either coaxial
or RJ-48.
The following clock synthesizer settings
are set by the software, and you cannot
change them:
For T1, the clock synthesizer is set to
1544 KHz.
For E1 the clock synthesizer is set to
2048 KHz.
Specifies the number of fractional T1 or
E1 channels to transport.
For fractional T1, enables or disables
fractional frame transport.
Specifies the signaling method used for
fractional E1.

Your Action
Select one:
RJ48
COAX
For T1, select a number from 1 through
24.
For E1, select a number from 1 through
31.
Select one:
y (yes)—Frame Transport—Framing
bit is transported along with data,
which results in data alignment with
the frame.
n (no)t—Framing bit is not
transported.
Select one:
n (no)—Common channel signaling
(CSS) is used. The common channel
carries data messages that convey
signaling for the circuits between two
devices.
y (yes)—Channel associated signaling
(CAS) is used. Each traffic channel has
a dedicated signaling channel
(channel 16).
