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 (Figure 1). 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 Cisco AS5350 Universal Gateway eliminates the need for switches and routers to create a point of presence (POP) or "POP-in-a-box" solution. The Cisco AS5350 has three primary universal gateway configurations: two Channelized T1(CT1)/Channelized E1(CE1)s, four CT1/CE1s, and eight CT1/seven CE1s. It also includes integrated signaling link termination (SLT) functions for direct connection to a Common Channel Signaling System 7 (SS7/C7) signaling gateway.
The Cisco AS5350 comes with two 10/100 autosensing Ethernet ports, which are ideal for redundancy and firewall applications. Additionally, two high-speed serial ports are provided to support Frame Relay, Point-to-Point Protocol (PPP), and High-Level Data Link Control (HDLC) backhaul. All backhaul interfaces support Hot Standby Router Protocol (HSRP), and all cards and the fan tray are hot-swappable 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.
