Example of provisioning rules for OC-48 BLSR (RPR provisioned on working channel)

In Figure 2-16 on page 2-36, a user provisions STS-1 #5 on the West optical interface (OC-48 in slot 11) as an RPR connection. See Table 2-4 on page 2-34for provisioning rules.

•STS-1 #29 on the East side is reserved for RPR provisioning because non-RPR connections may not be provisioned in the designated protection channels (any of STS-1 #25 through #48).

•STS-1 #29 on the East side cannot be a non-RPR protection channel because the working channel on the West side has already been provisioned as an RPR connection.

•STS-1 #5 on the East side is reserved for RPR provisioning because STS-1 #5 on the West side has been provisioned as an RPR connection. (See provisioning rule #3)

•STS-1 #29 on the West side is reserved for RPR provisioning because non-RPR connections may not be provisioned in the designated protection channels (any of STS-1 #25 through #48).

•STS-1 #29 on the West side cannot be a non-RPR protection channel because the working channel on the East side is already reserved for RPR provisioning. (See third bullet of this example, provisioning rule #3).
