Meridian SL-100 M3900 Meridian Digital Telephones Reference Guide
Program the MEARI interface to activate a ringer (or light) when the
telephone rings, or activate a recorder when the telephone is in use.
The MEARI requires an Accessory Connection Module (ACM).
MEARI connects to any M3900 set, except the M3901 which has no
accessory dock. In order to use the MEARI accessory, the telephone
must be equipped with the M3900 series ACM and power supply
(purchased separately).
The MEARI provides relay contact outputs for both ringing and call
status (off-hook condition) for activation of third-party peripheral
products such as loud ringers or call-in-progress indicators.
Additionally, the MEARI provides an audio output connection to voice
recording equipment (as permitted by law).
The audio output level from the MEARI varies with handset, headset,
and handsfree. Levels vary between local and remote speech, and
between users. For this reason, voice recorders with automatic level
control (ALC) circuitry provide the best quality recordings and uniform
recorded speech level. This is especially true for recording handsfree
conversations which provide the greatest range of speech level. The
MEARI provides the following features:
•
ring relay contact
•
call status (off-hook) relay contact
•
record audio
Since all three output signals operate independently, you can use the
MEARI for more than one purpose, such as loud ringing, call in
progress indication, and recording.
The MEARI does not require any software or system configuration.
Install the MEARI in the small dock of a M3902, M3903, M3904, or
M3905 series set. There are three output connectors on the back of the
MEARI cartridge. There is no need to disconnect the power supply from
the telephone prior to insertion or extraction of the MEARI cartridge.
Analog Terminal Adapter (ATA)
The ATA connects an analog device such as a fax machine or modem
to the telephone. This allows simultaneous use of the telephone and the
analog device. The ATA is available for the M3902, M3903, M3904, and
M3905 models. It requires an Accessory Connection Module.
