Digital Meridian
Integration Device The Digital Meridian Integration Device (DMID) is a device that provides
integration with Northern Telecom switches, such as the Meridian SL-1.
The DMID is located between the PBX and the voice server and appears
as one or two digital telephones to the PBX, depending on the number of
analog ports required. It is connected to the voice server via an RS-232
link. Analog line circuits for the voice path appear on the digital set of the
DMID. When a call is received on the DMID, it simultaneously rings at
the analog port. The DMID interprets the call display information and
transmits it to the voice server, which answers the caller with the
appropriate personal greeting.
VoiceBridge II The VoiceBridge II is a device that provides integration with several
switch types, including the AT&T G3 and the Rolm 9751. It is connected
to the PBX through one or more digital telephone lines and to the voice
server via an RS-232 link. When a call is received, the VoiceBridge II
routes it to an available voice port and transmits the call information to the
messaging server in SMDI format. The caller is answered with the
appropriate greeting.
