UNIVERSAL GATEWAYS AND ACCESS SERVERS Access Servers I.
Cisco AS 5350
The Cisco® AS5350 Universal Gateway is the only one-rack-unit (1RU) gateway supporting 2-, 4-, or 8-port T1/7-port E1 configurations that provides universal port data, voice, and fax services on any port at any time. The Cisco AS5350 Universal Gateway offers high performance and high reliability in a compact, modular design. This cost-effective platform is ideally suited for Internet service providers (ISPs) and enterprise companies that require innovative universal services.
The economic environment is prompting service providers to generate revenues quickly, improve returns from capital investments, and adapt to changing demands for various services in the market place. Cisco Any Service, Any Port (ASAP)—the architecture for rapid deployment of concurrent services on Cisco AS5000 universal gateways—allows service providers to meet these challenges. Cisco ASAP enables faster service introduction using a common platform for quick return on investment (ROI). Service providers can generate new revenue streams from multiple voice and data services such as long-distance voice over IP (VoIP), managed IP telephony, VPNs, and dial-up Internet.
Primary Features
Cisco ASAP 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 longdistance 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.
Modular Architecture 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.

Universal DSPs 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.
Remote Access Capabilities 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.

Cisco AS 5400
Cisco AS5400 Series Universal Gateways offer unparalleled capacity in only two rack units (2RUs) and provide universal port data, voice, and fax services on any port at any time. High-density (up to 1 CT3), lowpower consumption (7.2A at 48 VDC per CT3), and universal port digital signal processors (DSPs) make the Cisco AS5400 Series Universal Gateways ideal for many network deployment architectures, especially colocation environments and mega points of presence (POPs).
The Cisco AS5400 Series consists of two models, the Cisco AS5400 Universal Gateway and the Cisco AS5400HPX Universal Gateway. The Cisco AS5400 offers unparalleled dial capacity and scalability for MLPPP, L2TP, and V.120 sessions, whereas the Cisco AS5400HPX provides enhanced performance for processor-intensive voice and fax applications.
Cisco AS5400 Series Universal Gateways support a wide range of IP-based value-added services including high-volume Internet access, regional or branch-office connectivity, corporate VPNs, long distance for Internet service providers (ISPs), international wholesale long distance, distributed prepaid calling, Signaling System 7 (SS7) interconnect, and enhanced voice services.

Cisco AS5400 Series Universal Gateways support three primary universal gateway configurations: 8 CT1/CE1, 16 CT1/CE1, and 1 CT3. Two 10/100 autosensing Ethernet LAN ports are provided for LAN connectivity. Two high-speed serial ports support Frame Relay, Point-to-Point Protocol (PPP), and HighLevel Data Link Control (HDLC) backhaul. All backhaul interfaces support Hot Standby Router Protocol (HSRP), and all cards are hot-swappable for carrier-class resiliency. Integrated signaling link termination (SLT) is available to provide Cisco distributed message transfer part (MTP) SS7 signaling functionality. The rich set of Cisco IOS® Software features available in the Cisco AS5400 Series enables ISPs and enterprise network managers to meet traditional dial-in needs, including Internetwork Packet Exchange (IPX) and AppleTalk, while supporting the migration to new universal port services. The Cisco AS5400 Series supports widely deployed routing protocols, including those generally found in high-end access servers and routers: 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).
Key Features
Cisco ASAP Cisco ASAP architecture enables Cisco AS5400 Series Universal Gateways to operate simultaneously as a network access server (NAS) and a voice gateway, delivering universal services on any port at any time. Cisco ASAP services on the Cisco AS5400 Series Universal Gateways 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 AS5400 Series Universal Gateways achieve cost savings through optimized utilization 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.
Packet Telephony The framework for VoIP services on the Cisco AS5400 Series is based on open interfaces and standards, and it allows an ecosystem of partners to work together to develop innovative network services. Service providers are not locked into a single VoIP signaling technology when they choose Cisco AS5400 Series Universal Gateways—H.323, Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and Trunking Gateway Control Protocol (TGCP) support are all built in. This allows service providers to enable the call-control protocol that is the best fit for their network today, with the assurance that they can respond to evolving market requirements whenever necessary.
