M2000 Series Meridian Digital Telephones Page 13 of 104
M2000 Series Meridian Digital Telephones are designed to provide
cost-effective integrated voice and data communication. These telephones
communicate with the Meridian 1 using digital transmission over standard
twisted-pair wiring. They interface with the Meridian 1 using the Integrated
Services Digital Line Card (ISDLC), QPC578 or the Digital Line Card
(DLC), (NTAD02.). No additional hardware is required at the line circuit to
provide data communication.
M2000 Series Meridian Digital Telephones are connected to the system
through a two-wire loop carrying two independent 64 kbs PCM channels with
associated signaling channels. One of the two PCM channels is dedicated to
voice while the other is dedicated to data traffic. Line cords and handset cords
on all M2000 Series Meridian Digital Telephones are equipped with standard
modular connectors for easy and quick connecting procedures.
The telephone interfaces with the Digital Line Card (DLC) or ISDLC in the
Peripheral Equipment shelf of the system. The DLC supports 16 voice and
16 data ports. The ISDLC supports eight voice and eight data ports. A TN is
assigned to each port in the system software.
