Cisco SPA-1XOC48-ATM network interface processor

Cisco SPA-1XOC48-ATM network interface processor
Cisco 1-Port OC-48c/STM-16 ATM Shared Port Adapter



This data sheet details the features of the new modular OC-48c/STM-16 ATM SPA for Cisco 7600 Series routers. The Cisco 1-Port OC-48c/STM-16 ATM SPA, in conjunction with other SPAs implementing various types of network technologies, allows users to flexibly build cost-effective routing solutions that focus on point-of-presence (POP) and service provider core applications targeted for all telcos and Internet service providers (ISPs), for worldwide use. This SPA includes a comprehensive ATM feature set, including per-virtual circuit and per-virtual path traffic shaping; ATM service classes, including constant bit rate (CBR), non-real time variable bit rate (VBR-nrt), real-time variable bit rate (VBR-rt), unspecified bit rate (UBR), Layer 3 QoS, a high-performance segmentation-and-reassembly (SAR) architecture, and support for a large number of ATM virtual connections. All these features are based on industry specifications and standards.

The Cisco 1-Port OC-48c/STM-16 ATM SPA along with other ATM SPAs address the growing demand for improved ATM QoS features, combined with the advanced Layer 3 class-of-service (CoS) capabilities provided by various Cisco routers. Users now can provide robust QoS mechanisms for prioritization of traffic from traditional and high-speed LANs over an ATM network.

The Cisco 1-Port OC-48c/STM-16 ATM SPA can be inserted in the Cisco 7600 platform that supports various services such as:

- IPv4, IPv6, and Multiprotocol Label Switching (MPLS) hardware-assisted forwarding
- Enhanced security features such as extended access control lists (ACLs), Unicast Return Path Forwarding (uRPF), Internet Control Message Protocol (ICMP) rate limiting, and others
- Extensive QoS implementation based on either "classical" QoS (three type-of-service [ToS] bits), Differentiated Services (DiffServ [six differentiated services code point (DSCP) bits]), or MPLS (3 bits Experimental [EXP])
- Enhanced NetFlow, statistics, and billing data to allow service providers to generate different billing profiles for their customers
- MPLS VPN support that allows for Layer 3 VPN deployments and various related applications

The Cisco 1-Port OC-48c/STM-16 ATM SPA uses replaceable Small Form-Factor Pluggable (SFP) optical modules that allow customer flexibility in using different optical interfaces on the same SPA. It is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing removal of the SPA without impacting the interface processor and other SPAs.
