Loopback termination fails
with an error code of 1313.
The span is still looped somewhere, possibly at the
loopback jack, at the ICSU, or somewhere in the
network.
The red LED on the loopback
jack is on.
Replace the ICSU, and re-run the test.
Loopback termination still
fails.
Replace the DS1 circuit pack, and repeat the test
The DS1 cannot frame on
the incoming span’s signal
after the loopback jack power
down.
There is something wrong with the receive signal
into the loopback jack from the dumb block or the
smart jack.
The span failed the service
provider’s loopback test.
The problem is in the service provider’s network.
The service provider
successfully loop tested the
span, up to the smart jack.
The wiring between the loopback jack and the
smart jack is suspect. Test, and make repairs, as
needed.
You cannot locate and repair
the problem in the time
available and must terminate
the test.
The test will not terminate normally in the absence
of a good framing signal. You have to reset the
circuit pack. Enter
