Flexible vehicle for extending RPR rings  
Metropolitan Area Network (MAN) service providers today face the challenge of providing affordable and scalable 
packet data services while still offering a range of requisite TDM voice and private line services.  The Scientific-
Atlanta

 Prisma IP

™

 family of metro optical switches is designed to meet this need.  The Prisma IP Subtending 

Ring line cards are flexible solutions providing support for extending survivable optical rings to the access or 
network edge.  A single chassis can now “hub” multiple optical rings for efficient service aggregation.

 (RPT) rings – while maintaining stringent toll-quality 

parameters for TDM services.  The card set includes the Subtending Ring Card (SRC) front card and the 
Subtending Ring I/O Card (SRIO) rear card, and is available in two different versions:1.0 and 2.5 Gbps RPR/RPT 
rings.  A single M-Series Prisma IP can serve as a “hub” chassis for up to 12 subtending rings (6 protected).  A 
single C-Series Prisma IP can serve as a “hub” chassis for up to 4 subtending rings (2 protected).
