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-vt1:m-1-1-1,a-1-1:cct=dc,ring=m2:y;
7. Enter a drop and continue DS3/EC-1 cross-connect as follows:
1. At the first drop and continue node enter:
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 8-2 to verify this.
Protection Switch Test
This test verifies rings protection switching upon fiber cut.
1. At Site1NE1 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.
