Restoring Ds1 Administration; Releasing The Ds1 Circuit Pack; Testing The Ds1 Span From The Smart Jack To The Network Interface Termination Or Fiber Multiplexer (Mux) - Avaya MCC1 Installation And Upgrades

5
End the test. Enter test ds1-loop location end cpe-loopback-jack-test .
6
Wait about 30 seconds for the DS1 to reframe on the incoming signal and clear DS1 facility
alarms.
Condition
Loopback termination fails with
an error code of 1313.
The red LED on the loopback jack
is on.
Loopback termination still fails.
The DS1 cannot frame on the
incoming span's signal after the
loopback jack power down.
The span failed the service
provider's loopback test.
The service provider successfully
loop tested the span, up to the
smart jack.
You cannot locate and repair the
problem in the time available and
must terminate the test.
The test terminated normally.

Restoring DS1 administration

1
At the management terminal, open the DS1 administration form. Enter change ds1 location.
2
Change to page 2 of the DS1 administration form.
3
Change the value of the TX LBO field to the original value that you wrote down when you were
Administering the DS1 for the test
4
Press Enter to make the changes, CANCEL to quit without changes.

Releasing the DS1 circuit pack

1
Release the DS1 circuit pack. From the management terminal, enter release board location.
2
Leave the loopback jack in place.
Testing the DS1 span from the smart jack to
the network interface termination or fiber
multiplexer (MUX)
1
Have the service provider run a smart-jack loopback test against the network interface wiring that
links the smart jack to the CO (section 3 in
2
If the tests fails, there is a problem on the network side. Have the service provider correct it.
SI Installation and Upgrades
June 2004
Solution
The span is still looped somewhere, possibly at the loopback
jack, at the ICSU, or somewhere in the network.
Replace the ICSU, and re-run the test.
Replace the DS1 circuit pack, and repeat the test
There is something wrong with the receive signal into the
loopback jack from the dumb block or the smart jack.
The problem is in the service provider's network.
The wiring between the loopback jack and the smart jack is
suspect. Test, and make repairs, as needed.
The test will not terminate normally in the absence of a good
framing signal. You have to reset the circuit pack. Enter
reset board location.
