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 2-34
for 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 )
