ent-crs-sts1:m-1,a:cct=dc,ring=m1:y;
NOTE
:
The parameter ring defines the direction of the continued signal. Where
the traffic must be continued on the ring transmitting to the neighboring
drop and continue node. See Note Below.
NOTE
:
Ring
m1
is the ring that is received on the main-1 OLIU and is transmitted
on the main-2 OLIU.
Ring
m2
is the ring that is received on the main-2 OLIU and is transmitted
on the main-1 OLIU.
NOTE
:
For VT1.5 cross-connections, once the first VT drop and continue cross-
connection defines the ring direction, all other VT drop and continue cross-
connections at that node are forced to use that ring rotation.
2. At the second drop and continue node enter:
ent-crs-sts1:m-1,a:cct=dc,ring=m2:y;
8. Check each ring timeslot to be sure it has two end cross-connections and
all other nodes have pass-throughs configured. Use Office Records and
Table 9-2 to verify this.
Protection Switch Test
This test verifies rings protection switching upon fiber cut.
1. At the first site verify that no alarms exist.
2. Enter the command rtrv-state-path;.
3. Under the ‘act’ or active column, note whether traffic is received on M1
(main-1) OLIU or M2 (main-2) OLIU.
4. Disconnect the receive or ‘IN’ fiber of the OLIU receiving traffic (as deter-
mined by the previous step).
5. Enter the command rtrv-state-path;.
6. Verify that all traffic has switched from the OLIU with the disconnected fiber
to the OLIU that is still connected.
7. Reconnect the receive or ‘IN’ fiber.
8. Verify that alarms clear. If alarms do not clear refer to the ‘Troubleshooting’
Section of this manual. Continue with the next shelf.
