Write security: Config; Read security: Status
Allows users to provision the following options for
the DSX-1 interface.
F
ORMAT
This sets the frame format for the T1 interface. The
setting must match the frame format of the circuit to
which the interface is connected. Choices are ESF
and SF. Extended Superframe (ESF) provides a non-
disruptive means of full-time monitoring on the fa-
cility datalink (FDL). Default is ESF.

C
ODE
This sets the line code for the T1 interface. The set-
ting must match the line code of the circuit to which
the interface is connected. Choices are B8ZS (bipolar
with 8-zero substitution) and AMI (alternate mark
inversion). Default is B8ZS.
