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

2-34

for 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

).
