Testing The Ds1 Span From The Smart Jack To The Network Interface Termination Or Fiber Multiplexer (Mux); Testing The Ds1 Span From The Loopback Jack To The Smart Jack - Avaya G450 Installing And Upgrading

Power supplies and adjunct systems
10. To restore DS1 administration:
a. At the SAT, type change ds1 XXXVS to open the DS1 administration form.
b. Go to page 2 of the DS1 administration form.
c. 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.
d. Press ENTER to save the changes.
11. To release the DS1 circuit pack:
a. At the SAT, type release board XXXVS.
b. 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.

Testing the DS1 span from the loopback jack to the smart jack

Note:
This test cannot isolate the problem if there are problems in the wiring between
Note:
the far-end CO and the far-end MM710. 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.
1. Have the DS1 service provider at the CO end run a local MM710 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 G450 (for example, 002), and VS is the
slot number on the G450 of the Media Module (for example, V3).
b. Examine the bit-error counts, as in
page 267.
c. Type test ds1-loop location end-loopback/span-test to terminate the
test.
