The Cisco AS5350 universal gateway is the only one-rack unit, two, four, or eight T1/E1 gateway that provides universal port data, voice, wireless, and fax services on any port at any time. The Cisco AS5350 offers high performance and high reliability in a compact, modular design. This cost-effective platform is ideally suited for Internet Service Providers (ISPs) and enterprises that require innovative universal services. Universal port functionality enables the Cisco AS5350 to operate simultaneously as a network access server (NAS) and a voice gateway and deliver universal services on any port at any time. The Cisco AS5350 universal services include dial access, real-time voice and fax, wireless data access, and unified communications (UC). The Cisco AS5350 Universal Gateway achieves cost savings through optimized utilization of the universal port access infrastructure. Service Providers (SPs) can now quickly capitalize on new opportunities and realize multiple revenue streams from a single access infrastructure.The Cisco AS5350 eliminates the need for switches and routers to create a "POP-in-a-box" solution. The Cisco AS5350 has three primary universal gateway configurations: two CT1/CE1s, four CT1/CE1s, and eight CT1/CE1s. The two 10/100 autosensing Ethernet ports are perfect for redundancy and firewalled applications. Two high-speed serial ports are provided to support Frame Relay (FR), Point-to-Point Protocol (PPP), and High-Level Data Link Control (HDLC) backhaul. All backhaul interfaces support Hot Standby Routing Protocol (HSRP), and all cards and the fan tray are hot swappable for carrier-class resiliency. This is the only access server in this form factor that offers universal port capability with these high-availability features. The Cisco AS5350 supports widely deployed routing protocols, including those generally found in high-end access servers and routers (that is, 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]). This capability allows SPs and enterprises to deploy the Cisco AS5350 as a standalone "POP-in-a-box" universal port solution. Its rich set of Cisco IOS Software features 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 World Universal Port services. The Cisco AS5350 supports a wide range of IP-based, value-added services such as high-volume Internet access, regional/branch office connectivity, corporate virtual private networks (VPNs), mobile wireless solutions, long distance for ISPs, international wholesale long distance, distributed prepaid calling, Signaling System 7 (SS7) interconnect, wholesale dial/voice, and enhanced voice services. The Cisco AS5350 provides the perfect solution for telephony ASPs who would like to deploy PC-to-phone, Unified Communications, IP teleconferencing, voice-enabled Web commerce, and content delivery services.
