This data sheet details the features of the new modular ATM SPAs for Cisco XR 12000 Series Routers, the Cisco CRS-1 Carrier Routing System and the Cisco ASR 1000 Series. The Cisco ATM SPAs, in conjunction with other SPAs implementing various types of network technologies, allow the user to flexibly build cost-effective routing solutions focusing on point-of-presence (POP) edge, customer premises equipment (CPE), and enterprise applications.

Designed for all telcos and Internet service providers (ISPs), the Cisco ATM SPAs support a variety of port choices and granularity, including OC-3c/STM-1c and OC-12c/STM-4c interfaces for worldwide use. These modules are designed to support the convergence of data, voice, and video services, allowing customers to migrate existing voice and video traffic onto a corporate data network for substantial cost savings.

The Cisco ATM SPAs include a comprehensive ATM feature set including per-virtual-circuit and per-virtual-path traffic shaping, ATM service classes including constant bit rate (CBR), variable bit rate non-real time (VBR-nrt), variable bit rate real time (VBR-rt), unspecified bit rate (UBR), Multiprotocol Label Switching (MPLS), 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. In conjunction with the SIPs, the Cisco ATM SPAs continue to deliver new features made possible by industry-leading Cisco IOS® Software protocols, services, and an ATM-rich feature set.
