Example of provisioning rules for OC-192 BLSR (non-RPR provisioned on
working channel)
In Figure 2-19 on page 2-39 , a user provisions STS-1 #5 on the West optical
interface (OC-192 in slot 11) as an non-RPR connection. See Table 2-4 on
page 2-34 for provisioning rules.
• STS-1 #101 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 #99 on the East side. (See provisioning rule #
3 )
• STS-1 #101 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 ).
