Chapter 1 - Introduction

Overview

The Cubix MM 2008 (also referred to as the Cubix MM Series or MM adapter), is a multiple modem communications adapter with an ISA bus connector. The MM adapters provide a state-of-the-art combination of high speed controller and modems offering system administrators fast and reliable shared modem resources for networks. Using multiple MM adapters in a communications system allows the system administrator to manage a "modem pool" of simultaneous dial-in and dial-out asynchronous connections.

Up to fifteen MM adapters may be placed in a single subsystem, provided sufficient slots and power are available. Each MM adapter requires one 16-bit ISA (or EISA) slot.

Cubix Corporation supplies MM Series device drivers that provide access to the MM modems for use with any serial port application.

The heart of the MM 2008 is an on board processor with code optimized to move data to and from the on-board modems quickly enough to allow the modems to operate at their maximum baud rating. The included modems contain buffers to ensure that there will be no missed data at full rated speed.

The MM Series adapter comes with a breakout module that has eight RJ-11 sockets to connect the modems to analog phone lines.

An integral line busy module is used to simulate an "off hook" (or line busy) signal when the controlling application is not ready for a call or a server or modem fails (for example, due to a power failure). When the telephone system senses that the line appears busy, it automatically routes the call to the next non-busy line.
