MultiAccess ACS

Introduction

This guide shows you how to setup your MultiAccess ACS analog communication server, two-port model MA220, four-port model MA420 or eightport model MA820. All three units provide the same Remote Access Server, RAS, and modem sharing capabilities except for the number of ports each can provide. The MA420 and MA820 are provided in a desktop and rack mountable units where as the MA220 is provided in a desktop and wall mountable unit.

MultiAccess MA820

The MultiAccess ACS has two roles (usage), RAS and Modem Sharing. RAS Solution: The MultiAccess can be used as a dial-in PPP Remote Access

Server in a LAN to Client environment. The purpose is to give remote nodes (i.e., Microsoft Dail-up Networking clients) TCP/IP access to the same subnet and LAN the ACS is installed on. Masquerading (NAT) and LAN to LAN routing (assignment of an entire subnet) are IP networking techniques not supported by the ACS. The supported PPP security protocol (means of communicating user credentials between PPP end points) is PAP only.

Modem Sharing Solution: The modems in the ACS can be a shared resource on your network, commonly referred to as a network modem pool. Computers with network asscess to the ACS can use Telnet and get direct AT command access to one of the modems in the ACS, for either outbound or inbound calls. A common way to take advantage of this role is by installing Com Port Redirector Software (i.e., Multi-Tech’s MCSI2000 for Windows) on your workstations. The redirector adds a virtual com port to the workstation and uses Telnet to map, redirect, the com port to a modem in the ACS. The redirector and Telnet session replaces the UART based hardware of a PC and serial cable connection normally found in traditional modem installations. A communication program using this virtual com port has its data redirected to and from the modem within the ACS, making the modem appear as if it is directly attached to a communication port on the workstation.

Quick Start Guide

We Supply

• One MultiAccess unit with factory-installed software

• Two rack mounting brackets and four mounting screws for MA420 and

MA820

• One power cord for MA420 and MA820 or one universal power supply with power cord for MA220

• A product CD

• This printed Quick Start Guide

You Supply

• A nearby AC power outlet

• A connection to your Ethernet LAN

Safety Warnings

• Use this product only with UL- and CUL-listed computers.

• Never install phone wiring during a lightning storm.

• Never install a phone jack in a wet location unless the jack is specifically

designed for wet locations.

• Never touch uninsulated phone wires or terminals unless the phone line has been disconnected at the network interface.

• Use caution when installing or modifying phone lines.

• Avoid using a phone during an electrical storm; there is a risk of electrical

shock from lightning.

• Do not use a phone in the vicinity of a gas leak.

• To reduce the risk of fire, use only 26 AWG or larger telephone line cord.

• Disconnect this product from its power supply and telephone network

interface when servicing.

Caution: Danger of explosion if battery is incorrectly replaced. A lithium battery

on the MultiAccess PC board provides backup power for the time-keeping capability. The battery has an estimated life expectancy of ten years. Contact Multi-Tech if you suspect a failed battery. If data and time are incorrect after having the unit powered off, it may be due to a weak battery or incorrect setup.

Caution: The Ethernet ports are not designed to be connected to a Public

Telecommunication Network.

Safety Recommendations for Rack Instructions

• Ensure proper installation of the MultiAccess in a closed or multi-unit enclosure by following the recommended installation as defined by the enclosure manufacturer. Do not place the MultiAccess directly on top of other equipment or place other equipment directly on top of the MultiAccess.

• When mounting the equipment in a rack, make sure mechanical loading is even to avoid a hazardous condition, such loading heavy equipment in the rack evenly. The rack should safely support the combined weight of all equipment it supports.

• If installing the MultiAccess in a closed or multi-unit enclosure, ensure adequate airflow within the rack so that the maximum recommended ambient temperature is not exceeded.

• Ensure that the MultiAccess is properly connected to earth ground via a grounded power cord. If a power strip is used, ensure that the power strip provides adequate grounding of the attached apparatus.

• Ensure that the mains supply circuit is capable of handling the load of the MultiAccess. Refer to the power label on the equipment for load requirements.

• Maximum ambient temperature for the MultiAccess is 60 degrees Celsius (140° F).

• This equipment should only be installed by properly qualified service personnel.

• Only connect like circuits. In other words, connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications Network) circuits to TN circuits.

Hardware Installation (MA420 and MA820 only)

The MultiAccess is designed to install either on a desktop or in a standard EIA 19“ rack, and is shipped with the mounting hardware to install the MultiAccess in the rack. If installing in a rack, use the provided mounting hardware and follow the rack enclosure manufacturer’s instructions to safely and securely mount the MultiAccess in the rack enclosure. Proceed to the cabling procedure.
