Telephones and Consoles Description, Installation, and Operation
Analog Terminal Adapter
The Analog Terminal Adapter (ATA) enables the use of an off-the-shelf
analog device (FAX, Modem, Telephone) to operate simultaneously with the
Meridian Digital Telephones. The Analog Terminal Adapter board fits into
the footstand space of the Meridian Digital Telephone.
Functional description
The Analog Terminal Adapter is mounted in the footstand of the Meridian
Digital Telephone set. The ATA requires a separate AC adapter that provides
a 24 V AC external power source. The ATA does not draw power from the
Meridian Digital Telephone set.
The Analog Terminal Adapter (ATA) provides a RJ11 connection for analog
equipment to operate on the same line as the Meridian Digital Telephone set.
The Analog Terminal Adapter enables data to be transmitted and received
using the public switched telephone network (PSTN). The ATA supports an
analog device link to a desktop or laptop computer (with modems) in the
digital telephone environment. Currently, it is necessary to install a separate
analog phone line to be able to interface with the PSTN.
The ATA can be used for the following analog devices:
• FAX Machine
•Modem
• Analog Telephone
ATA operating parameters
The ATA data parameters are stored locally, although the configuration is set
in the CS 1000 and Meridian 1 system. Do not set data parameters in the
system before installing the ATA in the telephone. If the parameters are set
before the telephone is installed, the configuration information is lost.
Simultaneous voice and data capabilities are available. When the ATA is
installed, the System Administrator must activate the Flexible Voice and Data
feature by configuring LD 11. See Software Input/Output: Administration
(553-3001-311) for prompt and response details.
