Chapter 1 - Introduction and

Description

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.

Front Panel

The front panel has 16 front panel LEDs that provide operating status.

The Front Panel

Front Panel LED Descriptions

LED Description of LAN 1 & 2 LEDs

LINK The LINK LED indicates link integrity for the LAN Ethernet port. If the Ethernet link is valid at

either 10 Mbps or 100 Mbps, the LINK LED is lit. If the Ethernet link is invalid, the LINK LED is off.

ACT The ACT (Activity) LED indicates either transmit or receive activity on the LAN Ethernet port.

When activity is present on the LAN Ethernet port, the ACT LED is lit. When no activity is present

on the LAN Ethernet port, the ACT LED is off.

100MB The 100MB LED indicates the speed of the LAN Ethernet port. The 100MB LED is lit if the LAN

Ethernet port is linked at 100 Mbps. The 100 MB LED is off at 10 Mbps.

LED Description of LIne LI-1 thru LI-4 LEDs

LA The LA (Link Active) indicates layer 1 is up. LA blinks when Los of Frame Alignment (LFA) but not

Loss of Signal (LOS).

LC The LC indicates a red alarm.

LS The LS indicates a yellow alarm.

LED Description of Support Modem LEDs

CD The CD (Carrier Detect) LED lights when the modem detects a valid carrier signal from another

modem. It is on when the modem is communicating with the other modem. It is off when the link is

broken.

RD The RD (Read Data) LED flashes when the modem is receiving data from another modem.

DTR The DTR (Data Terminal Ready) LED lights when the operating system detects and initializes the

modem.

TD The TD (Transmit Data) LED flashes when the modem is transmitting data to another modem.

LED Description of System LEDs

HDD

ACT The HDD ACT (Hard Disk Drive Activity) LED lights when the MultiAccess hard disk drive is

accessed.

ALERT The ALERT LED lights and the system beeps when memory DIMM is bad, missing, or if other

rudimentary hardware failure.

POWER The POWER LED is off when the MultiAccess is in a reset state. When the POWER LED is lit, the

MultiAccess is not in a reset state.

Back Panel

The MultiAccess back panel has a fan, a power plug, the POWER Switch (| / O), an RJ-11 phone LINE jack,

a DB-9 COM1 jack, a DB-15 High-density DSUB (VIDEO) jack, two USB (Revision 1.1 compliant) jacks, four

RJ-45 T1/E1/PRI line jacks, and two Ethernet RJ-45 (Ethernet 1 & Ethernet 2) jacks.

The MultiAccess back panel is illustrated and described below.

Back panel

The back panel components are described in detail in the Cabling Procedure section in Chapter 2 of this

manual.

Chapter 1 – Introduction and Description

MultiAccess Communications Server MA30120 User Guide 9

Typical Application

Internet Service Provider (ISP) Application- Only one Ethernet interface on the MultiAccess is used.

The IP address of the MultiAccess and the pool of IP addresses for the dial-in users are of the same network

and normally are public addresses. The modems of the MultiAccess are configured for RAS usage. PPP

clients dial into the system, authenticate, via RADIUS, and establish a LAN to Client PPP session (remote

note).

Chapter 1 – Introduction and Description

MultiAccess Communications Server MA30120 User Guide 10

Corporate Application-One or both Ethernet interfaces can be used. When both interfaces are used, they

are commonly configured with separate network addresses. The MultiAccess can provide dial-in RAS to one

or both networks and provide modem sharing and faxing for network workstations. Workstations on the

corporate LAN can be a Comm Port Redirector (e.g., Multi-Tech’s WINMCSI) for accessing MultiAccess’s

modems. Authentication can be performed before granting access to the modem sharing resource, providing

another layer of security to your network’s infrustructure.

If some or all the MultiAccess’s modems are configured for faxing, the HylaFAXserver software needs to

be operating on the MultiAccess and the HylaFAX client software operating on the network workstation.
