Introduction
The TMDID8 board (trunk module direct inward dialing) provides direct inward dialing from the central office (CO) to the OfficePro.
The TMDID8 Module has eight trunk circuits that connect to analog trunks. The circuits convert incoming analog signals into pulse-code modulation (PCM) for processing by the digital OfficePro system.
The circuits can be set up for immediate start or wink start.
