Cisco Prisma IP HD SD-SDI Video Transport Cards Data Sheet
Ethernet Interface Solution for Multiple Services
Scientific-Atlanta’s Prisma IP
™
optical access switches deliver a new level of carrier-class reliability and
performance to Metropolitan Area Networks (MANs). This packet-based platform provides full support for legacy
voice and circuit services, while delivering a range of new differentiated data services.
Ethernet has emerged as the dominant LAN technology worldwide. The Prisma IP Ethernet 10/100 line card
provides carriers with a flexible interface to support applications such as Virtual LAN (VLAN), Ethernet, and IP
services. This standards-based interface offers auto-sensing support for 10 or 100 Mbps services with complete
rate-limiting capabilities for superior bandwidth management. Prisma IP is based on Resilient Packet Transport
(RPT), a superset of the emerging Resilient Packet Ring (RPR) protocol (IEEE 802.17). Prisma IP provides
carrier-class service for metropolitan optical networks requiring the highest level of availability, survivability, and
scalability to 80 Gbps.

Metro Ethernet Transport
The Prisma IP Ethernet 10/100 line card is optimized for
IP/Ethernet transport and provides Layer 2/3 support for switching
and routing. User ports can be configured for wire transport or for
dynamic routing within the Prisma IP network. Bandwidth
provisioning in 64 Kbps increments is provided for each individual
user port or VLAN. Classification of packets per DiffServ is
provided for up to three different classes. The 10/100 line card
supports both copper and fiber interfaces and offers 10 or 100
Mbps auto-sensing ports. Intra-card routing and switching is
provided via an internal routing table and switch fabric located on
each individual card. The card also is capable of reading the IP
TOS bits if required for Quality of Service classification.
