Feature description
The Meridian European Digital telephones series of telephones, which is only
available in Europe, 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
CS 1000 and Meridian 1 systems by using digital transmission over standard
twisted-pair wiring. They interface with the system 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
Intelligent Peripheral Equipment shelf of the system. The XDLC 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.
