Resilient Packet Ring (Rpr) Object - Nortel NTRN10AN Planning Manual

Resilient packet ring (RPR) object

A resilient packet ring (RPR) object is a SONET bandwidth pipe. See
2-33 on page
Bandwidth is allocated to the ring object from each of the optical circuit packs.
In this example, Packet Edge circuit packs are attached to the RPR object and
share its bandwidth.
The maximum number of nodes provisionable on a RPR ring is:
•
•
If the maximum number of nodes on the ring is exceeded a "Max OPE Nodes
On Ring Exceed" alarm is raised. For more information on this new alarm, see
RPR configuration alert on page
