Product Line(s)

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.
The Cisco ATM SPAs address the growing demand for improved ATM QoS features, which are combined with the advanced Layer 3 class-of-service (CoS) capabilities provided by various Cisco routers. Robust QoS mechanisms help prioritize traffic from traditional and high-speed LANs over an ATM network. Network managers can now cost-effectively terminate high-speed ATM, enabling rich QoS features for aggregation or campus applications.
The Cisco ATM SPAs can be inserted in the Cisco SIPs that support various edge services such as:

• IPv4, IPv6, and 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 DiffServe code point (DSCP) bits]), or MPLS (3 bits 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

• Any Transport over MPLS (AtoM) or pseudowire edge-to-edge emulation 3 (PWE3) support for transport solutions
The Cisco ATM SPAs use replaceable Small Form-Factor Pluggable (SFP) optical modules that allow customers the flexibility to use different optical interfaces on the same SPA. The Cisco ATM SPAs are hot-swappable and support service-transparent online insertion and removal (OIR), allowing removal of the SPA without impacting the interface processor and other SPAs.
