Cisco Prisma IP HD SD-SDI Video Transport Cards Data Sheet
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-

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.

Features
• Available versions include 1.0 or 2.5 Gbps RPR/RPT rings
• Extend TDM and transparent LAN services between rings
• 1+1 redundancy option and hot swap capability
• Supports dual ring protection for card and span
• Extends survivable ring topologies to the network edge
• May be installed in either an M-Series or C-Series Prisma IP chassis
• Subtending Ring is compatible with M-Series, C-Series and E-Series Prisma IP platforms
