500-19-54 Dual Channel Telephone Interface 2. SYSTEM DESCRIPTION 2.1 Features The telephone unit is a 1U unit containing a power supply and three printed circuit cards; these provide one or two channels of telephone interface. The digital hybrid card has smart algorithms to enhance line cancellation and reduce line howl round. It has software controlled parameters pre-set in the factory. The front panel controls are simple to use and there are indicators to show the status.
500-19-54 Dual Channel Telephone Interface 2.2 General 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.

The tones are an indication to the caller to enter the Direct Dial DTMF tones, if required, to call an individual panel within the Telephone group. This feature is only available when the TIC card is installed.

500-19-54 Dual Channel Telephone Interface 6. 500-19-21 DUAL HYBRID SET-UP 6.1 Introduction The 500-19-21 card carries two identical circuits and is controlled by the 700/500-19-00 interface cards and/or the front panel controls (see the previous section for information on the controls). Jumpers on the card allow matching to different line and exchange conditions as shown below. For details on the positions of the jumpers, please refer to the circuit board legend. 6.2 6.4 6.2 6.5 6.3 6.3 6.

500-19-54 Dual Channel Telephone Interface 7. 500-19-00 TELEPHONE INTERFACE CARD SET-UP 7.1 Introduction The 700-19-00 interface card acts as a buffer between the hybrid that connects directly to the telephone line and the audio and data circuits of the Commander matrix. Each card interfaces one telephone line to one matrix port. The card is largely digital, but there are three level controls that although factory pre-set, can be varied if necessary 7.
