Chapter 1 Introduction to the Remote Annex 6300
Remote Annex 6300 Supplement to the Remote Annex Administrator’s Guide for UNIX
Book A
The RA 6300 supports all of the dial-in, multiprotocol, remote access
features characteristic of other Remote Annex products. Moreover, ISDN
calls originating from a router (such as the Clam and Marlin) have access
to standard Annex IP routing capabilities.
Currently, the RA 6300 does not support dialout. This feature will be
available in a future release.
The above features allow network administrators to consolidate their
network needs into a single product that:
•
Supports analog calls, which are currently the predominant
access method for remote users.
•
Supports ISDN connections for the same users in the future.
The Primary Rate Interface
The RA 6300 provides a single ISDN Primary Rate Interface (PRI). The
PRI line connects to a PRI line module within the RA 6300. Two versions
of this module are available, one for the United States and another for
Europe:
•
The U.S. PRI module uses T1 as the physical medium and
supports 23 ISDN B channels and one D channel. The B
channels operate at 64 Kbps or 56kbps and carry user, voice
(modem), or digital data. The D channel is used for signaling.
•
The European module uses E1 as the physical medium and
supports 30 ISDN B channels and two D channels, one for
signaling and another for framing.
The PRI and the Ethernet port (en0) are the only physical ports on RA
6300. (Three types of Ethernet connectors are provided, but you use one
of them at a time.)
