Consider the two-fiber bidirectional line switched ring (2F-BLSR) shown in Figure 1.

1.what is the total available capacity of the ring for the transmission of the working traffic from ADM 1 to ADM 2 when A communicates with B

2.When all fibers are working

3.When fibers 2 and 8 fail

4.When fiber 12 fails after fibers 2 and 8 have failed

Assume that the capacity of each fiber is OC-12/STM-4

Consider the two-fiber bidirectional line switched ring (2F-BLSR) shown in Figure 1.
