General description

M2000 Digital Telephones provide a cost-effective 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 M2000 telephones. No
additional hardware is required in the loop circuit to provide data
communications, which provides a significant cost-savings potential.
M2000 Digital Telephones connect to the Meridian SL-100 system
through a two–wire loop carrying two independent 64-kbyte/s Pulse
Code Modulation (PCM) channels with two associated 8-kbyte/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 M2000 Digital Telephones have
snap-in TELADAPT connectors for easy and quick connection.
