Because of the strong personal computer presence in the business environment, a move to
graphical user interfaces, and the need to make the best use of available resources, there is a
growing 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 locations
has become a necessity.
With the demand for remote LAN access, the remote device’s requirement for bandwidth has
exceeded the capabilities of traditional analog modems. High-speed digital dedicated lines can
certainly provide sufficient bandwidth for LAN interconnection. However, because of the high
monthly 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 Digital
Network (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 the
bandwidth of dedicated digital service at dial-up prices.
Our products offer internetworking solutions for small businesses as well as large corporations.
The SmartSwitch Remote Access Modules are versatile wide area networking products designed
for the SmartSwitch 9000. They provide SmartSwitch 9000 users with an integrated solution for
both LAN and WAN access. Their capabilities and performance match the requirements that high-
end network connectivity users expect. The 9W006 and 9W007 expand the SmartSwitch
architecture to provide ISDN and analog modem access. The analog modem access is provided via
digital modem technology, and can be supported over ISDN or channelized T1 lines.
The 9W006 and 9W007 SmartSwitch Remote Access Modules are installed directly into the
SmartSwitch 9000. They include four flexible WAN interfaces providing ISDN, analog modem (via
digital modem), and T1/E1 or channelized T1 access. The 9W006 can support up to 96
simultaneous switched digital connections, and up to 48 simultaneous switched digital/analog
modem connections. The 9W007 can support up to 120 simultaneous switched digital connections,
and up to 60 simultaneous switched digital/analog modem connections.

ETWORK
The SmartSwitch Remote Access Module can be used with a mix of bridges, routers, hosts, PCs, and
workstations. These combinations provide internetworking capabilities that will allow devices to
carry out LAN-to-LAN applications such as telecommuting, electronic mail, multi-media
transmission, Imaging, and CAD. Devices “dial up” into a single system using a multi-line hunt
group to extend the capabilities offered by an enterprise LAN.
