T HE CYBERSWITCHBecause of the strong personal computer presence in the business environment, a move tographical user interfaces, and the need to make the best use of available resources, there is agrowing demand for high speed LAN access for remote devices. PC users need to be part of a work-group or enterprise LAN, and remote access from home, field offices, and other remote locationshas become a necessity.With the demand for remote LAN access, the remote device’s requirement for bandwidth hasexceeded the capabilities of traditional analog modems. High-speed digital dedicated lines cancertainly provide sufficient bandwidth for LAN interconnection. However, because of the highmonthly charges associated with dedicated services, the costs are prohibitive for individual users.New forms of networking are now possible and affordable using the Integrated Services DigitalNetwork (ISDN). ISDN is being deployed by major telecommunications companies world-wide.With ISDN services, the costs of LAN interconnection are based on actual usage — the user gets thebandwidth of dedicated digital service at dial-up prices.Our products offer internetworking solutions for small businesses as well as large corporations.T HE C YBER SWITCH NETWORKSystem software has been developed specifically for an embedded communications platform.
