Utilization of the redundant ring in SONET

Tue Jul 17 21:05:39 UTC 2001

Hello:

I would like to know how typical it is to have the redundant ring in
SONET used for the transport of data while still providing protection
switching features. Also, could any one give me insight into a few
vendors that does it. I would appreciate, if some one could provide
input on the above.

Regards,

Srihari Varada
