The following are new features in this release:

The Web Configuration Interface or Web Configurator is a browser-based

application for configuring features of your SuperStack

System1500. This new tool provides a platform-independent solution to

set up your unit and only requires that you run a browser (such as,

Netscape Navigator or Microsoft Internet Explorer) that supports HTML

4.0, or higher, JavaScript, and style sheets on your PC or UNIX

workstation. Details for setting up basic features of your RAS 1500 are

described in the SuperStack

Guide that is packaged with your system. You can also find this guide by

clicking on "Documentation" on the Release 2.0 Resource CD.

The Primary Rate Access Unit (PAU) is an ISDN PRI T1 or E1 access unit

that connects to your Router Unit via a STACKNET™. Once the units are

connected to the base unit, the system serves as one network entity,

managed as one device, by a single network management application.

Dynamic Host Configuration Protocol (DHCP), acting as a server, proxy, or

relay is a new component for this release. The RAS 1500 can serve as the

central DHCP server for both LAN-based and remote users. In addition, it

can "proxy" or "relay" IP address requests to another central server. This

feature simplifies network administration and enhances the mobility of

both remote and local users. The three DHCP scenarios are described

below:

Server - Acting as a DHCP server, the RAS 1500 receives and

processes requests for IP information from dial-in clients and provides

the IP information directly back to the client.

Proxy - Acting as a DHCP proxy, the RAS 1500 initiates a DHCP

requests to a DHCP server on behalf of a DHCP dial-in client. The

DHCP server receives and processes the request and sends the IP

information back to the dial-in client via the RAS 1500.

Relay - Acting as a DHCP relay, the RAS 1500 passes on a request for

IP information from LAN clients through a LAN-to-LAN connection to

a DHCP server.

This release of the RAS 1500 supports a PPP connection over a leased line

on its serial port. A leased line is a dedicated line between two sites and is

a permanently installed rather than a dialed up connection. PPP over the
