DS1 terminating equipment loopback testing
Facility Loopback testing allows the installer to verify electrical cabling to the DS1
Terminating Equipment. This test is only required if the 1665 DMX shelf is connected to
DS1 terminating equipment such as a DACS. It will be necessary to work with the
Customer Network Control Center to have them establish a terminal loopback. If the shelf
is NOT connected to DS1 terminating equipment, skip this section and continue with
non-terminating equipment transmission testing (optical main OLIU) (p. 4-11)
.
The Function Unit slot under test must contain a 28 DS1 (LNW6 or LNW7) or a
56DS1/E1 (LNW8) circuit pack in order to perform this test. The 56DS1/E1 circuit packs
can only be used with high capacity shelves. If the 1665 DMX shelf is not fully populated,
it may be necessary to move the circuit pack(s) from slot to slot in order to test all DS1
cabling.
Procedure
This command creates a cross-connect to map the first DS1 of a DS1 circuit pack in a
Function Unit to the first VT1.5 within the first VT Group of STS1 of the Main OLIUs.

1
Log on to the 1665 DMX shelf using the CIT software as described in
.

2
Select Configuration -> Cross-Connections...
........................................................................................................................................................................................................................
3
Use the Cross-Connection Wizard to enter a new cross-connection at the VT1.5 rate,
UPSR Ring Add/Drop, between m1-1-1-1-1 and fn1-1-1-1 (fn will be a,b,c or d depending
on the slot where the DS1 CP is located).

4
At this point it is necessary to have the Customer Network Control Center establish a
terminal loopback at the port under test at the DS1 terminating equipment.

5
Run a test transmission test to verify the electrical cabling.
Select Fault -> Test -> Transmission...

6
Select the CP, VT Group and Port 1-1 (DS1) associated with the cross-connection entered
above.
