General description

The Meridian M3000 Touchphone provides an integrated voice and data
communications capability. These telephones communicate with the
Meridian SL-100 system using digital transmission over standard telephone
(twisted-pair) wiring. The telephones interface with the Meridian SL-100
system through the Enhanced Digital Port Card (EDPC), which has 16 ports
that support 16 digital M3000 telephones.
M3000 Digital Telephones connect to the Meridian SL-100 system through a
two-wire loop carrying two independent 64 kbit/s Pulse Code Modulation
(PCM) channels with two associated 8 kbit/s signaling channels. One of the
two PCM channels is dedicated to voice, the other is dedicated to data.
Line cords and handset cords on all M3000 Digital Telephones are equipped
with snap-in TELADAPT connectors for easy and quick connection.
The M3000 Touchphone is a digital telephone with a touch-sensitive LCD
screen. All features are displayed on the screen. In the idle state, the screen
displays the time and date. The M3000 telephone can also display on-line
feature descriptions and operating instructions.
The M3000 offers a personal directory containing from 150 to 450 entries
(depending on the length of the entries). Each name in your directory is up
to 15 characters long with 8 names per page. Directory searching is
completed by scrolling up and down until the desired name is found. The
directory number is dialed by touching the name on the screen. The names
and directory numbers are entered, changed, and deleted quickly and easily.
The M3000 Touchphone has no moving mechanical parts like a key pad or
hookswitch. The touch-sensitive positions on the screen replace the key pad
and an infrared sensor hook replaces the mechanical switch.
