The Motorola Information Systems Group, subsidiary of Motorola Inc, has ramped up its push into the ISDN market with the introduction of its Vanguard ISDN Router family, designed to give users the ability to link remote users to corporate networks, local networks, the Internet, X.25 and Frame Relay networks in the one router. There are four routers in the family: Vanguard 100i ($800), 300i ($1,500), 305i ($2,000) and the 311 ($1,000). The 100i is a serial-only device, the 300i provides mixed Ethernet local network and legacy access to corporate networks, while the 305i is the Token Ring equivalent. The Vanguard 311 is targeted at ISDN-only applications with an Ethernet user interface. All routers are available immediately, except the 311 which is due to ship shortly.
