Procedure 7-8 (continued)
Testing STM-1/4/16/64/OC-3/12/48/192 protection switching with traffic on 2xGE(o) interfaces on
4xGE + 4xFE circuit pack
Step Action
10 Put the fiber back on the working path.
After the WTR time expires, the traffic will switch from protection to working
path.
11 Generate a loss of signal condition (LOS) on the working path by
disconnecting the fiber.
12 Put fiber back on the working path.
13 During WTR generate a loss of signal condition (LOS) on the protection path
by disconnecting the fiber.
Traffic switches back to work within 60 ms.
Go to step 15.
14 Generate a loss of signal condition (LOS) on the protection path by
disconnecting the fiber.
Traffic switches from the protection to the working path.
15 Put the fiber back on the protection path.
16 Record data in Table 12-11 on page 12-10/ Table 12-12 on page 12-11/ Ta ble
12-13 on page 12-12/ Table 12-14 on page 12-13 based on the STM/OC
value.
Note: Repeat the same procedure for other Ethernet port/WAN2.
—end—
If the protection
type is
Then
revertive traffic must switch from protection to working after the
WTR time expires and then go to step 11.
non-revertive go to step 14.
