1. INTRODUCTION  
1.1 Safety Precautions  
This equipment has been designed and tested to the highest safety standards. The following  
precautions should be covered to ensure safe operation of the apparatus.  
1.2 Transportation and Storage  
Careful inspection of the unit must be made after it has been subject to transportation or  
storage. Any serious damage, which could render it dangerous, must be acted upon to  
safeguard any potential user.  
1.3 Mains Connector and Plug  
The supply lead plug shall only be inserted into a supply socket equipped with an earth contact.  
Extension of the lead must include a suitable conductor for the protective earth.  
This equipment must be earthed.  
CSA requirements  
1) "The socket outlet shall be installed near the equipment and shall be easily  
accessible"  
2) "The Telephone Hybrid utilizes a AC power source; 90-250Vac, 50-60Hz,  
0.25 Amps per cord"  
1.4 Fuses  
Only the specified value and type of fuse must be fitted in the event of a replacement.  
The brown supply lead (live) is fitted with a series fuse located in the mains connector fitted on  
the rear panel. Should the unit be fitted with a two-pin plug then it is possible, if the supply is  
reversed, for parts of the equipment to remain at supply potential after the fuse has ruptured.  
1.5 Removal of Covers  
Care must be exercised if the covers of the unit are removed. All internal live parts are covered  
but the equipment should be disconnected from the supply source before repair or maintenance.  
Should it be necessary to carry out adjustments with the supply voltage connected then this  
work must be done by suitably qualified personnel.  
Note that capacitors in power supplies and mains filters can be charged when the equipment is  
disconnected from the supply. Before commencing work on the unit, these components should  
be discharged in a safe manner.  
It is important to note the designation of securing screws. These must be replaced in the  
positions to which they were supplied to reduce the possibility of damage to circuit boards  
mounted close to chassis securing screws.

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.

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. 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.  
The following diagram shows a typical installation.

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.

When in Auto mode, an incoming call will be answered with a blip of 2 tones being sent down  
the line. 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. This is set up in the configuration software.  
Whilst the Hybrid is active it will detect the presence of continuous tone (dial tone) for 6 seconds  
or a DC break on the line (K-break) to detect the caller has gone on-hook and to drop the line.  
This is done individually for each channel and configured by setting jumpers.

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 IMP  
This jumper allows matching of the line impedance to “CTR21”, to 600R or to a custom network  
by fitting components onto a plug-in header “Net1/2”. If you are not sure which setting to use ,  
try both “CTR21” and 600R and select the one with the best match to your line impedance, that  
is the setting with least voice feeding back.  
6.3 Dial Tone / K-Break  
In auto mode the line hold condition can be dropped automatically on detection of continuous  
dial tone for 6 seconds or by the detection of a break in the line current generated from the  
exchange, (called K break).  
With the jumpers fitted these signals will be detected. In some uses the automatic clearing by  
one or both methods might be a problem and the required jumper can be removed to disable  
detection.  
6.4 Reset Switch  
You can return the card to Factory Default by pressing and holding the button for about 6  
seconds. It will give 10 slow flashes and then speed up. When it speeds up let go and it will be  
reset.  
6.5 Programmable Port  
This is for factory use only.  
The Trilogy Dual Hybrid frame should only be connected to a Line via an appropriate  
approved fuse disconnection barrier.

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  
7.2 Ring Out  
This function that is pre-set by R33 controls the ring level heard at the caller’s earpiece when  
dialling in.  
7.3 Panel Ring  
This function that is pre-set by R29 controls the ring level at the panel when receiving an  
incoming call:-  
7.4 Panel DTMF  
This function that is pre-set by R28 controls the level of DTMF on the local panel’s loudspeaker  
when dialling out from the panel:
