for carrier-class resiliency. The Cisco AS5350 is the only gateway in

this form factor that offers universal port capability with these

high-availability features.

The Cisco AS5350 also supports widely deployed routing protocols,

including those generally found in high-end access servers and

routers (for example, Border Gateway Protocol Version 4 [BGPv4],

Open Shortest Path First [OSPF], Enhanced Interior Gateway

Routing Protocol [EIGRP], and Intermediate

System-to-Intermediate System [IS-IS] Protocol). This capability

allows service providers and enterprises to deploy the Cisco AS5350

as a standalone universal port solution.

The rich set of Cisco IOS

®

 Software features available in the Cisco

AS5350 Universal Gateway enables ISP and enterprise network

managers to meet traditional dial-in access needs, including

Internetwork Packet Exchange (IPX) and AppleTalk, while

supporting the migration to new universal port services.

The Cisco AS5350 supports a wide range of IP-based, value-added

services such as high-volume Internet access, regional- or

branch-office connectivity, corporate VPNs, long distance for ISPs,

international wholesale long distance, distributed prepaid calling,

SS7 interconnect, wholesale dial and voice, and enhanced voice

services. The Cisco AS5350 provides an ideal solution for telephony

application service providers (ASPs) that would like to deploy

PC-to-phone, voice portals, unified communications, IP

teleconferencing, voice-enabled Web commerce, and content

delivery services.

Cisco customers worldwide have proven that Cisco AS5000

universal gateways provide the flexibility, scale, reliability, and suite

of services required to meet market demands. By providing the

industry’s broadest family of access server products with universal

port digital signal processors (DSPs), Cisco Systems

®

makes it easy

for customers to select the right starting point for a phased rollout

based on revenue generation, without compromising future

capabilities. Complemented by the industry’s highest-rated service

and support, Cisco can also provide assistance with startup,

maintenance, and marketing tasks, as well as advanced and custom

solutions.

The Cisco ASAP architecture enables the Cisco AS5350 Universal

Gateway to operate simultaneously as a network access server

(NAS) and a voice gateway, delivering universal services on any port

at any time. The Cisco ASAP services on the Cisco AS5350 include

dial access, real-time voice and fax for local or long-distance

transport, managed services (hosted IP telephony, for example), and

unified communications on a call-by-call basis. Cisco AS5350

achieves cost savings through optimized use of the universal port

access infrastructure. Service providers can now quickly capitalize

on new opportunities and realize multiple revenue streams from a

single access infrastructure.

All feature cards can be upgraded in the field to accommodate future

technologies while providing a solution to meet today’s needs. The

removable system fan tray maximizes uptime.

The Cisco ASAP architecture is based on universal DSP technology.

The universal DSP can execute multiple coder/decoder (codec)

and modem algorithms on any DSP at any time. When the type of

codec or modem required for a specific call has been determined, the

DSP activates the appropriate service type in real time. When the call

is determined, different signaling schemes and modem negotiations

are used to determine the actual firmware code to be downloaded

onto the DSP for that particular call.

The Cisco AS5350 Universal Gateway takes advantage of the

full-feature richness and strong routing capabilities of Cisco IOS

Software. The Cisco AS5350 can be deployed in various

architectures, from multiprotocol corporate networks (IP, IPX,

AppleTalk, and NetBEUI, for example) to service provider IP

networks. In addition, the Cisco AS5350 fully supports the

specialized needs of AOL, MSN, and other content-oriented dialup

services through PPP, Layer 2 Tunneling Protocol (L2TP), or

Transmission Control Protocol Clear (TCP Clear) connections.

The Cisco AS5350 also supports the most complete set of access

protocols of any access server, including PPP, IPX Control Protocol

(IPXCP), AppleTalk Control Protocol (ATCP), AppleTalk Remote

Access (ARA), NetBIOS Frame Control Protocol (NBFCP),

NetBIOS over TCP/IP, NetBEUI over PPP, and protocol translation.
