Avaya Media Gateway G700 Manuale Utente

To test the DS1 span from the smart jack to the CO:

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.

Note:

This test cannot isolate the problem if there are problems in the wiring between 
the far-end CO and the far-end ICSU. You must coordinate this test with the DS1 
service provider.

Test the short length of customer premises wiring between the loopback jack and the smart jack 
(Section 2 in the following 3 figures) using a loopback that overlaps this section of the span.

To test the DS1 span from the loopback jack to the smart jack:

1. Have the DS1 service provider at the CO end run a local ICSU line loopback test.

2. Have the DS1 service provider at the CO end run a local DS1 payload loopback test. 

3. Run a far-end MM710 line loopback, using the following procedure: 

a. From the SAT, type test ds1-loop XXXVS far-csu-loopback-test-begin

, where XXX is the administered number of the G700 (for example, 002), and VS is the slot 
number on the G700 of the Media Module (for example, V3). 

b. Examine the bit-error counts, as in 

c. Type test ds1-loop location end-loopback/span-test to terminate the test.

If the tests fails and the there were no problems 

, there is a problem between the loopback jack to the smart jack. Work 

with the service provider to isolate the fault.
