Using the HY-03

Receiving a Call

With the equipment connected as in Figure 1-4 calls may be received and detected by the

ringer in the telephone handset. To receive the call, lift the handset and establish contact

with the caller. The call may be diverted to the telephone hybrid by pressing either the front

panel mounted line connect switch or by means of the remote divert switch (if connected).

Alternatively, the incoming calls can be answered automatically by enabling the integrated

ringing detector. It is recommended that the K-break line clearance is used when the ringing

detector is enabled. When the ringing detector is in use, ringing tone will illuminate the

line connect switch. The line connect switch lamp is o in the non-connected mode and

illuminated in the connected mode.

Note : The remote lamp tally mimics the front panel line connect switch lamp, i.e. it

ashes when ringing and is on when the line is held.

The hybrid unit will now behave as a 4 wire to 2 wire converter with signal inputs at the

mic/line Input connector and telephone signal output at the output connector.

The call may be cleared by repressing the line connect switch or by means of the remote

divert switch. The call can also be cleared automatically by enabling either the K-break

disconnect or the dial tone disconnect (using the optional HY-03DTD dial tone disconnect

plug-in PCB).

With both auto-answer and auto-clearance in use, call handling can be completely

automatic in operation.

Making a Call

To initiate a call, lift the handset and dial the required telephone number. When the call

has been established, press the line connect switch and the call will be handed over to the

telephone hybrid unit. To clear the line at the end of the call, press the line connect switch.

The line connect switch lamp is o in the non-connected mode and illuminated in the

connected mode.
