4.4. Mitel Superswitch PBXs

Mitel PBXs use digital signaling to control its station sets and digitized voice.

Digital Network Interface Circuit (DNIC) Line Cards provide an interface

between the station sets and the switch. The Dialogic

PBX Integration Board

has four or eight channels that can be connected to a Mitel DNIC Line Card.

The PBX Integration Board can be used with the SX-50, SX-200, and SX-

2000 PBXs. These Mitel PBXs have many standard features that are supported

by the PBX Integration Board, such as:

• direct inward dialing (DID)

• speed dialing

• hunt groups

• message waiting indication

• user programmable Feature Keys

• called/calling number identification

• call forwarding
