Figure 8-23 shows a 1-way circuit that has been established on a 2-fiber
bidirectional ring with 1-way STS-3 cross-connections at FT-2000 OC-48

2-Fiber Bidirectional Ring
At node 0, traffic is rolled from low-speed interface slot 2B to low-speed
interface slot 4A by specifying:
— Source (slot)
— Source low-speed interface slot
*
(slot 2B)
— Destination line (line 1E)
— Destination STS-3 tributary (tributary 6)
— New cross-connection type (1-way)
— New source (slot 4A).
* If the specified slot is part of a slot pair (for example, slot 1A and 1B) that has been
provisioned for the OC-3 1+1 (Release 5 or later releases) protection mode, specifying one
slot also includes the companion slot. The same type of logic applies to OC-12 1+1
(Release 7.1 or later releases) protected mode.
