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

In Figure 2-17 on page 2-37, a user provisions STS-1 #5 on the West optical interface (OC-48 in slot 11) as an non-RPR connection. See Table 2-4 on page 2-34for provisioning rules.

•STS-1 #29 on the East side is reserved as a non-RPR protection channel. (See provisioning rule #1, provisioning rule #3)

•STS-1 #5 on the East side is reserved for non-RPR provisioning because RPR provisioning rules over BLSR conflict with STS-1 #5 on the West side and STS-1 #29 on the East side. (See provisioning rule #3)

•STS-1 #29 on the West side is reserved as a non-RPR protection channel because STS-1 #5 on the East side is non-RPR. (See last bullet of this example, provisioning rule #3).
