Configures the T1 for the appropriate line buildout, based on the distance to the T1 equipment. By default,
the line buildout for the TRACER 4102/4202 is

Determines whether the TRACER 4102/4202 unit will report active alarms. If set to
D
ISABLED
, no alarms will
be displayed on this menu page. The
A

R
EPORTING
parameter is independently configured for the local
and remote TRACER 4102/4202 units. When set to
D
ISABLED
, the front panel LED alarms are also disabled
(OFF). By default, alarm reporting is set to
E
NABLED

IGNALING
Configures the framing format for the T1 link for both the local and remote TRACER 4102/4202 units. The
TRACER 4102/4202 transports T1 data across the link (as long as the T1 signal is properly timed). Configure
the framing format (using the
S
IGNALING
menu) to enable the TRACER 4102/4202 to monitor incoming
framing error events and indicate problems with the attached metallic service. The TRACER 4102/4202
supports both extended superframe (
ESF
) and superframe (
D4
) framing formats. By default, the signaling
method is set to
ESF
.

]
Activates a loopback at the local TRACER 4102/4202 T1 framer towards the remote end of the wireless link
(see Figure 9). Use the local
L
INK
loopback to loop the data transmitted from the remote end of the link back
across the radio link to the remote end of the link. This loopback tests the integrity of the radio link and all the
associated digital and RF hardware.
