42. Repeat Steps 34 through 36 for each path being
tested.
—
43. At the FT-2000 primary node P', reset the manual
DRI switch for each path being tested. Use the
FAULT-Switch-Path-STS3-Reset command for
the appropriate line(s) and tributary(s).
—
44. Verify that there are no alarm or status conditions in
the ring.
—
45. This completes testing path integrity (Figure 4). —
46. This completes testing path integrity (Figure 4) in the
local FT-2000 ring. If the external network is
non-Lucent (another vendor), refer to local
maintenance procedures to test path integrity in that
ring. If the network is a DDM-2000 ring, refer to the
appropriate manual as follows:
—
63-206-202 for DDM-2000 OC3 for Releases 2 through 7.2
63-206-280 for DDM-2000 OC3 for Release 8 and Higher
63-206-207 for DDM-2000 OC12/OC12 Regenerator for Releases 1
through 3.1
63-206-290 for DDM-2000 OC12 for Release 5 and Higher
47. The local FT-2000 ring has two DRI cross-connections to the outside. Both DRI
cross-connections terminate to external networks.
Verify that there are no alarm or status conditions in
either ring (Figure 5).
—
48. At the transmit end in the external network (left side),
insert a verifiable signal into each path being tested.
—
49. At the receive end in the external network (right
side), verify the detection of the inserted signal on
each path being tested.
—
50. To test path integrity for 2-way paths, repeat Steps
48 and 49 from opposite ends of each path.
