13 TRANSPOND
This function allows the receiving party to send the
acknowledge message after the transceiver receives a
call. The transceiver also transmits the Transpond Tone
when the Acknowledge is sent.
Using this function, a user can confirm a transceiver is
within communication range.
Transceiver operation varies between an Optional
Signaling call and LTR ID call.
13.1 Transpond Using Optional
Signaling
The transceiver sends an acknowledge message to the
dispatcher after receiving the individual call with
2-tone or DTMF, or DTMF Stun code.
Note:
Transpond does not function with group calls.
Transpond is cancelled when the channel is changed while the
transceiver is in Transpond Standby Mode.
If Clear to Transpond is enabled, the transceiver does not
transmit Transpond while the channel is being used.
13.3.1 Clear to Transpond on page 38.)
13.2 Transpond Using the LTR ID
(TK-3173 only)
This function allows the transceiver to send an
acknowledge message to the dispatcher after the
transceiver receives a call with the LTR ID. The
transceiver starts transponding when the Transpond
Delay Time elapses. (Refer to 13.4.1 Transpond Delay
Time on page 38.)
Note:
If the ID used for transponding is received during the scan, the
transceiver starts transponding after the Transpond Delay Time
elapses. The transceiver resumes scanning after the Dwell
Time elapses. If the Dropout Delay Time is shorter than the
Transpond Delay Time, the transceiver starts transponding after
the Dropout Delay Time elapses.
Transpond is cancelled if the Zone or GID is changed during the
Transpond Delay Time.
While Transmit Inhibit is enabled, the transceiver does not start
transponding. (Refer to 15.1.19 Transmit Inhibit (Block ID) on
page 47.)

13.3 Conventional Group
13.3.1 Clear to Transpond
Clear to Transpond forces the transceiver to wait while
other users are using a channel before starting to
transpond.
Clear to Transpond can be configured to be enabled or
disabled by using KPG-101D. Clear to Transpond can be
configured for 2-tone and DTMF.
Configuration using KPG-101D
• Configuring the Clear to Transpond (DTMF) (Refer
to FPRG 6.10.2 Decode Tab - Clear to Transpond.)
• Configuring the Clear to Transpond (2-tone) (Refer
to FPRG 6.11.2 Decode Tab - Clear to Transpond.)
13.4 Trunking System
(TK-3173 only)
(Refer to
This function allows the transceiver to send an
acknowledge message to the dispatcher after the
transceiver receives a call with the LTR ID. The
transceiver starts transponding after the Transpond Delay
Time elapses.
Transpond can be configured to be enabled or disabled
for each Group ID by using KPG-101D.
Configuration using KPG-101D
• Configuring the Transpond (Refer to FPRG 6.6.11
Transpond.)
13.4.1 Transpond Delay Time
The Transpond Delay Time is the time between when the
transceiver receives a Group ID for which Transpond is
enabled and when it sends the Transpond code.
If the Dropout Delay Time is shorter than the Transpond
Delay Time, the transceiver starts transponding after the
Dropout Delay Time elapses.
Delay Time on page 112.)
The Transmit Delay Time can be configured by using
KPG-101D.
Configuration using KPG-101D
• Configuring the Transpond Delay Time (Refer to
FPRG 6.7.4 Trunking Tab - Transpond Delay
Time.)
