Cisco Prisma IP Point-to-Point Gig Ethernet and MPEG-2 ASI-C Transport Cards Data Sheet

 

 
 
 
Ethernet Card for Packet Aggregation or Routing 
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, and Gigabit Ethernet is rapidly becoming the key 
interface for metro Ethernet access.  The Prisma IP Gigabit Ethernet line card provides carriers with a flexible 
interface to support applications such as rate limiting Virtual LAN (VLAN), and Ethernet/IP aggregation services.  
This standards-based interface card offers support for rate-limiting capabilities, packet aggregation, routing, and 
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. 

 

 

•  IEEE 802.3 compliant 

•  Modular GBIC form factor interfaces 

•  Hot swappable without service interruption 

•  Forwarding and queuing 

•  High packet throughput for line-rate forwarding 

•  Individual port assignment to wire or routing modes 

•  Rate-limiting of bandwidth per individual port 

•  Short, intermediate, and long-reach optics 

•  Compatible with both M-Series and C-Series Prisma IP chassis 

 
 

Metro Ethernet Transport, Routing and Aggregation 
The Prisma IP Gigabit Ethernet line card is optimized for 
IP/Ethernet transport and aggregation and provides Layer 2/3 
support for switching and routing.  User ports can be configured 
for wire transport or for dynamic routing.  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 Gigabit Ethernet line card supports 
several fiber interfaces and offers auto-sensing/auto-negotiating 
ports.  These fiber interfaces include short, intermediate and 
long-reach optics.  Intra-card routing and switching is provided 
via an internal routing table and switch fabric located on each 
individual card.  The Gigabit Ethernet line card can be used as 
an aggregation point into a core WAN or other metro ring.
