This chapter describes the Meridian Communications Adapter (MCA), the
Meridian Programmable Data Adapter (MPDA), the Asynchronous Data
Option (ADO), the Meridian Communication Unit (MCU), and the Analog
Terminal Adapter (ATA). This chapter also describes several software
features.
The M2317 can be equipped with an Asynchronous Data Option (ADO) to
allow you to make a data call using keyboard dialing from your attached
terminal or personal computer. Voice and data communications can be
conducted simultaneously without causing any mutual interference.
The ADO mounts within the telephone and works in conjunction with the
Digital Interface Chip to provide asynchronous communication up to
19.2 kbps from an ASCII data terminal or a personal computer to the
Meridian 1 Integrated Services Network. The ADO appears as Data
Circuit-terminating Equipment (DCE) in your terminal and connects to the
Data Terminal Equipment (DTE) through an RS-232-C connector mounted
on the ADO printed circuit board.
