The ImageSteam Gateway Router™ is the perfect low-cost solution for IP applications that demand wire-speed routing over T1/E1, DS3/E3 and OC3 circuits, with options including gigabit ethernet, DC power, and redundant AC or DC power supplies.

The Gateway Router includes an easy-to-service 19-inch 4U rackmount chassis, industrial computer, high-speed error-correcting memory, 12-slot PCI backplane, and 10/100 ethernet port. The Gateway Router uses flash storage with no moving parts to maximize reliability.

Each PCI slot accepts LAN and WAN adapters including all Industrial Series network cards, ethernet cards with up to four ports, and token ring cards. With these add-on cards, the Gateway Router can interconnect IP networks using multiple 56/64 K DDS, fractional and full T1/E1, fractional and full DS3/E3, OC3, token ring and ethernet connections.

The Gateway Router takes advantage of Standard Architecture for Network Drivers (SAND), which includes modular support for WAN protocols including PPP, Cisco HDLC, frame relay and ATM. SAND also makes it easy to troubleshoot LAN and WAN connections by providing real-time port status and performance monitoring.

The Gateway Router is Case Communications' most popular solution for midrange router applications that require wire-speed performance and superior reliability in an easy-to-service package. The Gateway Router works where most Cisco 3600, 3700 and 7200 series routers are used, and it includes support for firewall security and IPsec virtual private network (VPN) applications.

The Gateway Router can be used in a wide range of applications from the core to the edge. It is commonly used by Internet Service Providers (ISPs) for multihomed networks that require dynamic routing, high-density T1/E1 routing, and multiport DS3/E3 and OC3 connectivity. The Gateway Router is the industry’s lowest cost OC3 router, and it is ideal for midrange ISP applications and corporate networks where a high level of scalability and redundancy is required.
