Data Sheet

Cisco Shared Port Adapters/SPA Interface Processors

Cisco 1-Port OC-3c/STM-1c ATM SPA, 3-Port OC-3c/STM-1c ATM

SPA, and 1-Port OC-12c/STM-4c ATM SPA

The extensible Cisco® I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs),

enabling service prioritization for data, voice, and video services. Enterprise and service provider customers can take

advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco

routing platforms. The I-Flex design maximizes connectivity options and oﬀers superior service intelligence through

programmable interface processors that deliver line-rate performance.

I-Flex enhances speed- -service revenue and provides a rich set of quality- -service (QoS) features for premium to of

service delivery while eﬀectively reducing the overall cost of ownership. This data sheet contains the speciﬁcations

for the Cisco 1-Port and 3-Port OC-3c/STM-1c ATM, and Cisco 1-Port OC-12c/STM-4c ATM Shared Port Adapters

(refer to Figure 1).

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.
