Introduction
The Meridian European Digital telephones series of telephones consists of the
following telephones:
•M3110
•M3310
•M3820
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) or the eXtended Digital Line Card (XDLC).
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.
The telephone interfaces with the Digital Line Card (XDLC) or ISDLC in the
Peripheral Equipment shelf of the system. The XDLC supports 16 voice and
16data ports. The ISDLC supports eight voice and eight data ports. A TN is
assigned to each port in the system software.
