Chapter 1 - Introduction and
Welcome to Multi-Tech's new MultiAccess Communications Server, Model MultiAccess. The MultiAccess
Communications Server is a high-performance digital remote access solution for Enterprise LANs and
Intranets or Internet service providers. MultiAccess is a V.92 remote access server (RAS) supporting up to
four T1 line interfaces implementing either RBS or PRI signaling for use in North America or up to four E1
line interfaces implementing PRI signaling for the rest of the world. The MultiAccess Communications Server
uses a web based Graphical User Interface (GUI) for configuration, is a 1U (one-up) rackmountable unit that
contains up to four universal modem ports for dial-in communications.
WAN Communications
MultiAccess ships turnkey for T1/RBS or T1/E1 PRI ISDN and populated with 30 modems on line interface 1
for the basic configuration. Additional modem modules can be added to support up to four T1/E1 line
interfaces. The high-density modems provide V.92/56K dial-up speeds. In addition, they are manageable
from remote locations using platform-independent, industry standard protocols.
Management
MultiAccess includes robust management support allowing a network administrator to securely manage the
devices either through a web browser or at the command line. The browser-based option uses the HTTPS
protocol, also know as SSL (Secure Sockets Layer) to provide 128-bit encryption to secure the management
session. The command line interface is accessible via SSH (Secure Shell) and supports SCP (Secure Copy)
and sftp (Secure File Transfer Protocol) to help provide maintenance support.
SNTP Support. MultiAccess includes an industry standard Simple Network Time Protocol (SNTP) client that
enables it to synchronize its clock with a remote time/clock server on the Internet. This feature is useful for
accounting purposes.
Remote Access
Comprehensive Security. MultiAccess provides an industry standard Radius Server and Radius Client for
authentication and authorization of thousands of user profiles using PAP and CHAP. In addition, it uses
Network Address Translation (NAT) to hide internal, non-routable IP addresses. If a Radius Server does not
exist, one is provided as part of the MultiAccess system. This Radius Server could provide authentication
and authorization information for this and other Radius Clients in use at your site.
