Interphase Tech RAS Communications Controller 5536 - Manual (Page 22)

Overview
2 Interphase Corporation
The 5536-DM RAS software can provide secure connections
by interfacing with a Security Dynamics® ACE/Agent®
installed on the local machine. This ACE/Agent
communicates with a Security Dynamics ACE/Server®
located either on the local machine or anywhere on the local
network.
The board handles connections on ISDN B and D channels.
The ISDN channels are accessible using RAS and digital
modems. The board is designed for remote access systems that
allow dial-in from ISDN or PSTN (analog) networks,
combining the two most popular dial-up access services under
a single call number. The software supports ISDN calls, which
are numerically terminated, and digital modem calls, which
are analog terminated, simultaneously on ISDN B channels.
The communications controller features a high-performance
multi-function architecture. The onboard processor off-loads
communications protocols such as ISDN signalling from the
host CPU, boosting overall performance. Also, the board can
be quickly and easily expanded to support evolving features or
network technologies.

The single-port version of the 5536-DM RAS is referred to
internally as the 5536-1P-PRI. The dual-port version is
referred to internally as the 5536-2P-PRI. You might see
these names used in the Users Guide and the software
