Restricting IDs for Which the Talkback Is Available (Unit ID Encode Block)
Unit ID Encode Block is the Unit ID range that the transceiver can respond (Talkback).
Unit IDs to which a user is allowed to respond (Talkback) can be restricted using KPG-169D/ KPG-170D/ KPG-175D.
The transceiver unmutes the speaker and emits received audio when the transceiver receives the Unit ID satisfying the
receiving conditions. The receiving transceiver can respond (Talkback) to the transmitting transceiver by a user pressing
the PTT switch. However, the transceiver cannot respond (Talkback) if the transceiver is inhibited to respond (Talkback) to
the Unit ID of the transmitting transceiver.
Note
• The transceiver can respond (Talkback) to a Unit ID configured in the Unit ID List even if it is outside the Unit ID Encode Block range.
• The transceiver for which Unit ID Encode Block is not configured can respond (Talkback) to all transceivers.

8.4 Initiating an Individual Call After Ensuring That the Target Party Is
Available for Communications (Individual Call Acknowledge Request)
Individual Call Acknowledge Request is the function that allows a user to distinguish whether or not the receiving
transceiver is available to communicate so as to initiate an Individual Call.
The Individual Call Acknowledge Request enables a call to the particular transceiver having the specified Unit ID, in the
same way as a normal Individual Call does; however, an acknowledgment message must be received from the receiving
transceiver before the communication starts (or receiving an Individual Call from the receiving transceiver also allows the
communication to start).
The transmitting transceiver sends a message requesting an acknowledgment when initiating an Individual Call. Upon
receipt of the message requesting an acknowledgment, the receiving transceiver sends to the transmitting transceiver an
acknowledgment message to notify that the receiving transceiver is available for the call. The transmitting transceiver
becomes enabled for the communication upon receipt of the acknowledgment message from the receiving transceiver.
To use this function, Individual Call Acknowledge Request must be enabled on the transmitting transceiver by using
KPG-169D/ KPG-170D/ KPG-175D. Also, using KPG-169D/ KPG-170D/ KPG-175D, the parameters of the following
various functions to be used with Individual Call Acknowledge Request can be configured.
• Call Request Tone
• Call Processing Tone
• Call Processing Tone Delay Time
• Automatic Response
• Initiating/Incoming Reset Time
Note
• Individual Call Acknowledge Request cannot be used while the transceiver is placed in Emergency Mode. A normal Individual Call,
which does not require the sending of a message requesting an acknowledgment, can only be used.
• For an Individual Call (Individual Call Acknowledge Request), the following functions used for a normal Individual Call are available.
(Refer to 8.3 Making an Individual Call/ Paging Call on page
• Unit ID List
• Unit ID Encode Block
• For Portable, if Individual Call Acknowledge Request is enabled, the VOX function cannot be used in an NXDN Conventional system.
