G.703 DTE Loopback
A G.703 DTE Loopback loops the received signal from the G.703 interface back to
itself, retaining bipolar violation (BPV) transparency. If the G.703 port is configured
in a DS0 cross-connection, the time slots cross-connected to the G.703 port are
sent all ones. If the G.703 port is in Bypass mode or a DS1 cross-connection, all
ones are sent to the corresponding port and data received on the connected ports
will be ignored.
Procedure
To run a G.703 DTE Loopback:
1. Position the cursor at the Start command next to G.703 DTE Loopback on
the DSL & G.703 Tests screen.
2. Press Enter.
The Start command is changed to Stop. Status is changed to Active.
3. To manually stop the test, verify that the cursor is positioned at the Stop
command.
4. Press Enter.
Status is changed to Inactive.
The G.703 DTE Loopback cannot be started when any other loopback is
in progress. If the G.703 port is used for inband management, inband
management is unavailable for the duration of the test.
