Notifying the User with a Tone That a Call Request Has Been Initiated (Call Request
Tone)/ Notifying the User with a Tone That a Call Request Is in Progress (Call
Processing Tone)
Call Request Tone
is the function to sound a Call Request Tone (1 beep) from the transceiver when a call request for an
Individual Call or Group Call is initiated by pressing the
PTT
switch in a P25 Trunking system.
Also,
Call Processing Tone
is the function to sound a Call Processing Tone (2 beeps) from the transceiver while the
PTT
switch is pressed and held after a call request for an Individual Call or Group Call is initiated by pressing the
PTT
switch in
a P25 Trunking system.
Depending on the system condition, it may take few seconds to determine the call request upon the initiation of a call request
using Individual Call or Group Call. Use of this function notifies a user by emitting a tone from the transceiver of the condition
from when the transceiver initiates a call request using Individual Call or Group Call until the call request is determined.
When the transceiver initiates an Individual Call or Group Call using this function, the transceiver behaves as follows:
