8.2 Using the Signaling
8.2 Using the Signaling
RAN code is the signaling to be used for facilitating communication within a group if the same channel is shared by several
groups. Also, NXDN ID can be used as the Optional Signaling to initiate a selective call.
Sharing the Same Channel (Frequency) by Several Groups (RAN)
RAN (Radio Access Number) is a digital signaling type having the same function as analog QT tone or DQT code. This
signaling is used when the transceiver transmits or receives on a digital channel.
By configuring a RAN code for each channel, the transceiver mutes calls from a group having a RAN code which is not
preconfigured for the transceiver. Therefore, a user can communicate in a group without listening to conversations from
other groups.
The transceiver can distinguish the signaling even if the transceiver receives any signaling during a call since this signaling
type has a continuous waveform.
Following is transmission and reception behavior of a RAN code.
If the RAN code in a received signal matches the preconfigured RAN code in the transceiver, the transceiver
Reception
unmutes the speaker and emits the received audio from the speaker.
The transceiver sends the preconfigured RAN code while transmitting. Pressing the PTT switch causes the
Transmission
transceiver to send the RAN code.

Using the Optional Signaling (NXDN)
Optional Signaling is the signaling used to initiate a selective call. NXDN ID is the Optional Signaling which can be used in
an NXDN Conventional system.
NXDN ID is the signaling type using the Unit ID or Group ID stored in the NXDN data frame. The transceiver emits a
ringing tone (Alert Tone) in the case that the received RAN code matches the RAN code preconfigured in the transceiver
and the received Unit ID or Group ID matches the Unit ID or Group ID preconfigured in the transceiver.

Unmuting the Speaker (Audio Control (NXDN))
Audio Control is the condition which allows the transceiver to unmute the speaker by a RAN code and an Optional
Signaling. The conditions on which the transceiver unmutes the speaker can be configured for each channel.
The transceiver unmutes the speaker and emits received audio if the conditions configured for Audio Control are satisfied.
Conditions to unmute the speaker can be changed by a combination of the RAN code and the Optional Signaling.
Following are the conditions to unmute the speaker.
