The support of SONET ring interfaces in the Prisma IP

™

 system enables network 

operators to deploy new, high bandwidth, managed services over legacy networks.  
Designed to integrate smoothly into existing networks, Prisma IP allows operators to 
derive the greatest performance and revenue potential from existing SONET/SDH 
infrastructures. 
 
Resilient Packet Ring (RPR) and MPLS technologies enable network operators to 
offer high revenue voice, video, and data services to residential and business 
customers.  The bandwidth efficiency, resiliency, and simple end-to-end provisioning 
allow operators to more quickly and cost-effectively deploy new services.  Key 
applications include: 
 

-  Transparent LAN Service 
-  Video Transport  
- Ethernet Transport 
-  TDM Private Line Transport 

 
The RPR over SONET/SDH interface cards support SONET OC-3 to OC-48 (SDH STM-1 to STM-16) rates.  Ring 
speed is software selectable.  The Prisma IP ring I/O card is the main optical transceiver interface between the 
Prisma IP shelf and the optical transport network.  Each RPR ring I/O card supports two pluggable optic modules 
transmitting and receiving packet data to and from adjacent nodes.
