ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

2. Introduction

This chapter introduces Router technology, features, and applications. Installation instructions begin in Chapter 3.

If you are upgrading a previous version of the Router, make sure you read Appendix C in the Reference Manual.

The Routers are remote access servers that route TCP/IP and IPX (NetWare®) traffic. Routers connect remote local area networks (LANs) and clients to Ethernet-based LANs, using standard V.34 modems, or synchronous lines (leased or switched). Personal computers can access Router servers using the Async Client software. Macintosh® and other non-PC clients can dial into a Router using the standard point-to point protocol (PPP).

Three models are available:

2.1 Applications

All Router models provide autosensing Ethernet interfaces (10BASE-T, AUI), and support multiple protocols for both LAN-to-LAN and user-to-LAN (remote-client access) routing. All Routers have an internal V.34 modem (the AR-5 model has five internal modems).

2.1.1TRANSPARENT LAN-TO-LANROUTING

For transparent routing between separate Ethernet-based LANs, pair two Routers together or use compatible devices. Use any Router model to provide inexpensive networking solutions for remote of fices. For maximum throughput, use the Sync Router for synchronous connections.

2.1.2TRANSPARENT REMOTE CLIENT ACCESS

For remote client access, the Router acts as a remote node server, allowing IPX- and TCP/lP-based PCs and laptop computers to become remote nodes on an Ethernet-based network attached to the Router. Remote client workstations can then dial into the Router to access services on the LAN as if they were local nodes. The Router supports transparent access for a maximum of 100 remote clients, and accepts calls from any client on any dial-up modem line configured for client access.

2.1.3REMOTE CLIENTS AND LANS WITH DUAL-STACK FUNCTIONALITY

Router supports dual-stack functionality in both remote LAN-to-LAN and remote client operations. IP and IPX protocols are supported, so that any DOS or Windows® based PC, Macintosh, or UNIX® workstation can access the Router. The Router uses the standard PPP protocol, which allows third-party client applications to access the Router.
