Product Overview

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- -presence (POP) edge, customer premises equipment (CPE), and enterprise of

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- ), unspeciﬁed bit rate (UBR), Multiprotocol Label Switching (MPLS), QoS, a high-performance rt

segmentation- -reassembly (SAR) architecture, and support for a large number of ATM virtual connections. All and

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.

Data Sheet

The Cisco ATM SPAs address the growing demand for improved ATM QoS features, which are combined with the

advanced Layer 3 class- -service (CoS) capabilities provided by various Cisco routers. Robust QoS mechanisms of

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- -service [ToS] bits), of

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- -edge emulation 3 (PWE3) support for transport to

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.

Applications

The Cisco ATM SPAs are designed for a wide range of network applications. The speciﬁc combination of ATM

features and standards makes the Cisco ATM SPAs ideal for both enterprise-based ATM WANs and service provider

infrastructures.

Enterprise-Based ATM WAN

ATM technology is now a favored choice for very high-bandwidth corporate connectivity across an enterprise WAN.

Providing connectivity to geographically dispersed facilities, typical ATM WAN interfaces range from 34 to 622 Mbps.

These very large WAN pipes supply ample bandwidth for the needs of corporate infrastructures today, with room for “ ”

growth in the future. Enterprise-based ATM WANs can be deployed through private networks or through a public

ATM service from large service providers.

With the many advanced ATM capabilities and support for MPLS and QoS (such as per-virtual-circuit and per-virtual-

path traﬃc shaping), the Cisco ATM SPAs are ideal for interconnecting Cisco XR 12000/CRS-1 Carrier Routing

System at central sites or larger remote sites through an enterprise-based ATM WAN. The Cisco ASR 1000 Series

can be deployed for WAN aggregation of branch oﬃces. Through OC-3c/STM-1c or OC-12c/STM-4c ATM links, the

Cisco ATM SPAs can be connected to any standards-based ATM WAN switch, including the Cisco LightStream

1010, Cisco Catalyst® 8500 Series, Cisco MGX® 8800 Series, Cisco BPX 8600 Series, and Cisco IGX 8400 Series at

the switching core.

In the campus backbone or metropolitan-area network (MAN), the OC-12c/STM-4c provides the same scaled-up

ATM bandwidth as in the POP when the bandwidth between the ATM switches is increased.

The Cisco ATM SPAs allow you to combine a diverse range of LAN technologies, including Fast Ethernet and Gigabit

Ethernet, with ATM in enterprise deployments.

Data Sheet

Service Provider Infrastructures

ATM deployment in service provider infrastructures has seen tremendous growth in recent years as well. This growth

has been spurred for several reasons:

● ATM provides highly scalable bandwidth within SONET/SDH infrastructures.

● ATM is inherently a multiservice (data, voice, and video) technology.

● ATM is based on international standards.

The Cisco ATM SPAs provide high-performance interconnectivity for service provider intra-POP applications needing

IP transport. Cisco ATM SPAs can also be used for ATM aggregation of remotes sites at the edge of the service

provider networks.

Because they support ATM Forum speciﬁcations and IETF and ITU standards, the Cisco ATM SPAs can be deployed

with any standards-based ATM switch, including the Cisco MGX 8800 Series, Cisco BPX 8600 Series, Cisco IGX

8400 Series, Cisco LightStream 1010, and Cisco Catalyst 8500 Series products.

The Cisco ATM SPAs in conjunction with the Cisco SIPs allow service providers to eﬀectively manage the bandwidth

at the edges of the network while implementing value-added Layer 3 services. With advanced traﬃc-shaping features

and support for many ATM service classes, the Cisco ATM SPAs can be widely deployed in many parts of the service

provider backbone. Advanced traﬃc-management features (such as per-virtual-circuit and per-virtual-path traﬃc

shaping) are required to prevent traﬃc from one customer impacting traﬃc of another.

Layer 2 Transport Services

In order to cost-eﬀectively deliver new revenue-generating connectivity options to their customer base, traditional

ATM and Frame Relay service providers (telcos, regional Bell operating companies [RBOCs], and incumbent local

exchange carriers [ILECs]) are migrating services from cell-based ATM transport networks to packet-based MPLS/IP

networks. This migration allows them to deliver the rich functionality of services associated with Layer 3 while gaining

the ability to account for, prioritize, and eﬀectively oﬀer these services for proﬁt.

Using the Cisco ATM SPAs in conjunction with the Cisco SIPs, by tunneling core ATM trunks through an MPLS/IP

network, you can take advantage of your existing investment in IP networks networks that are currently low-–

revenue-generating and, in essence, enable those networks to mimic and build upon the class- -service (CoS) –of

abilities of current Frame Relay- and ATM-based networks, all while maintaining continuity of Layer 2 services.

Features and Beneﬁts

The ATM SPAs oﬀer many advantages, including support for the following features:

● Per-virtual-circuit and per-virtual-path traﬃc shaping: Traﬃc shaping is a function typically provided on ATM

edge devices to ensure that bursty traffic conforms to a predetermined “contract.” To implement traffic

shaping, the Cisco ATM SPAs support per-virtual-circuit and per-virtual-path shaping, including industry-

leading minimum 1-kbps granularity, allowing ﬂexibility and control over every virtual circuit and virtual path

conﬁgured.

● IP QoS and Layer 3 QoS features: The Cisco SIPs and ATM SPAs support per-virtual-circuit IP QoS features

that allow you to apply advanced-queuing and bandwidth-management functions, including Low Latency

Queuing (LLQ), to individual virtual circuits to avoid congestion and delay. In addition, extended ACLs and

committed access rate (CAR) are supported on a per-virtual-circuit basis on both ingress and egress.

● IP/MPLS- -ATM QoS mapping: Also supported is IP- -ATM QoS setting through cell-loss priority (CLP) bit to to

support and virtual circuit bundling, which allows you to divide traﬃc on diﬀerent virtual circuits, depending on

the desired CoS.
