Configures the framing format for the E1 link. The TRACER transports E1 data across the link (as long as
the E1 signal is properly timed). Configure the framing format (using the

menu) to enable the
TRACER to monitor incoming framing error events and indicate problems with the attached metallic
service. The TRACER supports
service. The TRACER supports
M
ULTIFRAMED
(also known as CAS),
U

(all data stream with no
framing sequence bits), and
F

(also known as CCS). The default value is

ODE
Sets the line coding for the E1 link. The TRACER supports high-density bipolar 3 substitution (
HDB3
) and
alternate mark inversion (
AMI
) line coding. HDB3 coding does not allow more than three consecutive
zeros in a transmitted bit stream and is the standard coding method on public networks.
