DS1/T1 CPE loopback jack
555-233-116
144 Issue 4 October 2002
NOTE:
If you have a G700 Media Gateway, substitute XXXVS for UUCSS in the
following command, 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). The V is not a variable and needs to be included in the
command exactly where shown. A sample address for a DS1 circuit pack on
a G700 Media Gateway might look like this: 002V3.
1. From the management terminal, enter test ds1-loop UUCSS far-
csu-loopback-test-begin, where UU is the cabinet number, C is
the carrier letter, and SS is the slot number of the DS1 board.
2. Examine the bit-error counts, as in ‘‘Testing the integrity of data sent
over the loop’’ on page 139."
3. Terminate the test. Enter test ds1-loop location end-loopback/
span-test.
3. If the tests fails and the there were no problems ‘‘Testing the DS1 span
from the ICSU to the loopback jack’’ or ‘‘Testing the DS1 span from the
smart jack to the network interface termination or fiber multiplexer (MUX)’’,
there is a problem between the loopback jack to the smart jack. Work with
the service provider to isolate the fault.
