500-19-54 Dual Channel Telephone Interface

2.2General

The unit contains one dual hybrid card 500-19-21 which can be used as either a means of converting 2 telephone lines to a line level 4 wire circuit or, if installed with one or two TICs (Telephone Interface Card 500-19-00 for Commander and 700-19-00 for Mercury), allow a full DTMF telephone integration with the Trilogy system. For information on the software integration of the frame into a system refer to the Pathfinder User Guide (chapter 17) or the Mercury Configuration Manual.

Telephone Line

The Dual Hybrid module plugs into the second card slot of the frame, the first and third slots are for channel one and channel two Telephone Interface cards (TIC) respectively.

Each channel of the digital Dual Hybrid has identical features. The line interface has jumper selectable CTR21 or 600 ohms that allows the hybrid to operate in the majority of countries. Also provided on the card is a DIL header to allow the addition of a balance network when required. This is normally done after consulting Trilogy Support.

The provision of the optional parallel handset connection when auto is set to off this allows for manually setting up and answering calls when used in conjunction with the manual seize and drop controls on the Hybrids front panel. If the front panel switch is selected to Auto the parallel handset will be disconnected.
