Compatible Systems Corp is promising that up to four T1 circuits can connect to its RISC Router 3500R – a Tunneling/wide area network router designed for private networks. According to the company, the router will link up to four T1 circuits and up to 256 Frame Relay PVC permanent virtual circuits. The RISC Router 2600i delivers the same 4 x T1/E1 capabilities for Internet service providers. Both routers have 4 high-speed synchronous V.35 connectors supporting speeds to 2.048Mbps. All wide area network ports may be used at full bandwidth simultaneously, enabling remote user dial-in or multiple remote network and/or Internet connections. The routers support local connections to an Ethernet network via 10BaseT or thick Ethernet. Future enhancements to the routers will include support for MPPP, Multi- Link Point-to-Point Protocol, to allow bonding of separate T1 channels. The RISC Router 3500R Tunneling/Wide Area Networks Router with four High-Speed Synchronous V.35 Wide Area Network ports, and one Ethernet port supporting TCP/IP, IPX, AppleTalk, DECnet costs $4,500. The RISC Router 2600i High-Speed Internet Router with four High-Speed Synchronous V.35 Wide Area Network ports and one Ethernet port costs $3,500.
