NENA/PHONE MIC SOURCE SETUP
The NENA/PHONE MIC SOURCE SETUP section is used to configure microphone source priorities when a
NENA/phone is active on the ADHB-4. Up to three (3) different microphone sources can be set up when a
NENA/phone is connected and onhook. Once the NENA/phone is taken offhook (low), the ADHB-4 transmits full-duplex
audio to the NENA/phone.
NOTE: A NENA/phone cannot operate without headsets selected that are configured for use at the console position.
The default for these fields is:
Headset Mic #1
RHB 1 #2
RHB 2 #3
EXAMPLE: When the defaults are sets the audio is routed as follows:
If a headset, an RHB 1, and an RHB 2 connected, and the NENA/Phone is taken offhook, audio is routed to
the headset’s earpiece.
If an RHB 1 and an RHB 2 are connected, and the NENA/phone is taken offhook, audio is routed to the
RHB 1.
If an RHB 2 is connected, and the NENA/phone is taken offhook, audio is routed to the RHB 2.
