®
II Remote Access System 1500 Quick Setup
Guide that is packaged with your system. You can also find this guide by

Primary Rate Access
Unit (PAU)
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)
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.
PPP Over Serial WAN
Port
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
