>DS3 STATUS/CONFIGURATION/LOOPBACK > DS3 LINE BUILD OUT
Configures the DS3 for the appropriate line buildout, based on the distance to the DS3 equipment. Use
DSX for 0-255 feet and HIGH for distances greater than 255 feet.
>DS3 STATUS/CONFIGURATION/LOOPBACK > ALARM REPORTING
Determines whether the TRACER 4205 unit will report active alarms. If DISABLED, no alarms will be
displayed on this menu page. The ALARM REPORTING parameter is independently configured for the local
and remote TRACER 4205 units. When disabled, the front panel LED alarms will also be disabled (OFF).
>DS3 STATUS/CONFIGURATION/LOOPBACK > SIGNALING
Configures the framing format for the DS3 link for both the local and remote TRACER 4205 units. The
TRACER 4205 transparently transports DS3 data across the link (as long as the DS3 signal is properly
timed). Configure the framing format (using the SIGNALING menu) to enable the TRACER 4205 to monitor
incoming framing error events and indicate problems with the attached metallic service. The TRACER
4205 supports both
M13 and C-BIT parity modes.
>DS3 STATUS/CONFIGURATION/LOOPBACK > LINE CODE
Sets the line coding for the DS3 link. The TRACER 4205 supports only B3ZS line coding.
>DS3 STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE
Controls the loop status of the DS3 link. Activates/deactivates loopback conditions for testing purposes.
>DS3 STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE > NORMAL
The DS3 link is in normal data transport mode - there are no active loopbacks.
>DS3 STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE > LINK
Activates a loopback at the TRACER 4205 DS3 framer towards the wireless link (see Figure 7). Use the
LINK loopback to test data path integrity from one unit across the wireless link.
Figure 7. DS3 Link Loopback
LOS Activates when no DS3 signal is present from the connected DS3 equipment. LOS is
activated after receiving 192 consecutive zeros.
LOF Activates when the DS3 framer loses alignment due to too many F bits or M bits in error.
IDLE Connected DS3 equipment is indicating that the line is not in use by transmitting a
properly aligned and frame 1100... pattern.
