DO ITEMS BELOW IN ORDER LISTED . . . . . . . FOR DETAILS, GO TO
31. Verify that there are no alarm or status conditions in
the ring.
—
32. This completes testing path integrity (Figure 3). —
33. The local FT-2000 ring has two DRI cross-connections to the outside. One DRI
cross-connection terminates in an external network and the other DRI
cross-connection terminates directly to test sets.
Verify that there are no alarm or status conditions in
thering(Figure4).
—
34. At the transmit end in the external network, insert a
verifiable signal into each path being tested.
—
35. At the receive test set, verify the detection of the
inserted signal on each path being tested.
—
36. To test path integrity for 2-way paths, repeat Steps
34 and 35 from opposite ends of each path.
—
37. At the FT-2000 primary node P, execute a manual
DRI switch for each path being tested. Use the
FAULT-Switch-Path-STS3(or STS1)-Manual
command for the appropriate line(s) and tributary(s).
—
38. Repeat Steps 34 through 36 for each path being
tested.
—
39. DO NOT RESET the DRI switch at node P at this
time. At FT-2000 primary node P' (P prime), execute
a manual DRI switch for each path being tested. Use
the FAULT-Switch-Path-STS3(or
STS1)-Manual command for the appropriate line(s)
and tributary(s).
—
40. Repeat Steps 34 through 36 for each path being
tested.
—
41. 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).
