Procedure for EC-1 Testing
1. Beginning with address ‘a’, place a physical DS3(EC-1) loopback at ONLY
this address at the DSX-3 panel. If more than one loopback is present
incorrect wiring may not be apparent. If DS3/EC-1 cabling connects directly
to DACS IV 2000 have Craft personnel put up an internal loopback or con-
nect the DS3 ‘in’ cable to the DS3 ‘out’ cable using a BNC to BNC connec-
tor.
2. Remove the DS3(EC-1) loopback.
3. Issue the
rtrv-alm
command and observe that an ‘Inc. EC-1 LOS’ alarm
exists for this address.
4. Replace the DS3(EC-1) loopback.
5. Issue the
rtrv-alm
command and observe that the ‘Inc. EC-1 LOS’ no
longer exists. If the alarm exists, correct the problem by checking circuit
packs and associated cabling. An ‘Inc. STS AIS’ will occur if VT cross-
connects exist.
6. The physical DS3(EC-1) loopback can remain until service is applied. Ver-
ify that no ‘Inc. EC-1 LOS’ alarms exist and continue testing the next chan-
nel.
Procedure for Removing Cross-Connects
After all function groups are tested and verified as functioning properly, the cross-
connect map needs to be deleted. There are two ways to delete cross-connects;
choose the appropriate method.
1. To delete DS1 cross-connects issue the command:
dlt-crs-vt1:m-1-all,a-all:y
;
Replace ‘m-1-all,a-all’ with the address to be deleted.
2. To delete DS3/EC-1 cross-connects, issue the command:
dlt-crs-sts1:m-1,a:y
;
Replace ‘m-1,a’ with the address to be deleted.
NOTE
:
If cross-connects remain, VT AIS alarms will remain until cross-connects
are entered for all remaining shelves in the ring.
3. To delete all cross-connects, an INITIALIZE-SYSTEM command is used.
The
init-sys
command is a privileged user command and thus the
appropriate login is necessary. Refer to the ‘Login Procedure’ Section ear-
lier in this section. Issue the command
init-sys:all
;.
