code directly. The repeater will transfer the received DTMF code to the PSTN

gateway to connect the phone system for communications between the radio and

the phone. When a call is received from the phone, the radio needs to send the

DTMF code to put through the call. During the call, the phone can receive the voices

transmitted by any other radio in the system. Likewise, the voice transmitted by the

phone will be received by any radio in the system.

In digital mode, the radio will transmit signalings and the DTMF code to the repeater.

Then the repeater will transfer the DTMF code to the PSTN gateway device to

connect the phone system and put through the call. When the buffer dial is used, the

radio call type matches the type of the transmitting contact on the channel. If a

private call contact is selected as the transmitting contact, the radio will make a

private call to the phone. The radio can receive call from the phone and private calls

from other radios simultaneously. If a group call contact is selected, the radio will

make a group call to the phone. All group members can communicate with the

phone upon establishing this call. If an all call contact is selected, the radio will make

an all call to the phone. All radios in the system can communicate with the phone

upon establishing this call. During live dialing, the call type depends on which kind of

call is initiated upon holding down PTT, but is not necessarily associated with the

transmitting contact on the channel. During buffer dialing, the call type is consistent

with the type of the transmitting contact when you make a call from the contact list.

Generally, what kind of call the phone initiates to the radio is subject to the type of

the transmitting contact in the repeater. However, if the radio makes a private call

whose ID is the repeater’s ID, the call type has no bearing on the type of the

transmitting contact in the repeater.

After a radio sends the Access Code and talks with the phone, the phone will receive

voice from other radios in the system. In this case, interference may occur if several

radios send voice simultaneously. The voice from radio with strong RSSI will replace

one from radio with weak RSSI.
