1500
The RAS 1500 offers extensive access security, dialback, and easy
configuration for terminal service connections.
Network Dial-in Access
RAS 1500 provides dial-in network access for remote users. Remote IP,
IPX and Appletalk network users can dial in and connect to the local
network as if they were local nodes.
Packets transmitted over the dial-in connection are encapsulated using
the following protocols:
■
PPP (Point-to-Point Protocol)
■
SLIP (Serial Line IP Protocol)
■
FCP (3Com’s Fast Connect Protocol)
Dial-out Access
You can access RAS 1500 ports with network computers and
workstations to provide users with NCSI and Telnet dial-out services. This
allows network users to connect to Bulletin Board Systems (BBSs) or
information services such as CompuServe, or access the Internet over a
dial-up connection.
IP or IPX LAN users require a NCSI-compatible communications
application to access RAS 1500 modems.
LAN-to-LAN Routing and Bridging
RAS 1500 performs dial-up routing over a PPP connection between
facilities. Routing occurs when one device dials up another device and
logs in as a user.
There are several types of LAN-to-LAN connections:
■
Manual
■
On demand
■
Timed
■
Continuous
RAS 1500 supports many routing and protocol configurations. It is
capable of establishing additional connections to increase bandwidth
automatically when network traffic increases.
