Connection with the SRG3900
mobile radio
Your console works using the SRG3900 mobile radio, with the optional
provision of the Applications Interface Unit (AIU).
Console and Application Interface Unit
The SRG3900 mobile radio supports the connection of up to two consoles,
either a Standard Console, Colour Console or a Handset-Based Console (via
an Interface and Handsfree box), or an Applications Interface Unit, which is
similar to a console but does not have a keypad and display. Through the use
of a console, the SRG3900 mobile radio can support the connection of up to 6
of the following audio accessories:
up to two hands-free kits
up to four standard handsets
up to four standard fist microphones
If two consoles are fitted, they display the same information. This makes it
possible to move from one console to another without having to take any
special action. If two users are using the same mobile radio, operational
procedures are required to ensure that the actions of the two users do not
conflict.
On some configurations it is possible to have a hands-free kit attached to each
console. If this is the case, only one of the remote microphones is live during
a call. The remote microphone which is live is the one attached to the console
which accepted or made the call or switched the call to hands-free.
Mobile radio audio control
The mobile radio supports the concept of a single controlling audio accessory
for a call. The controlling audio accessory is the one in control of the call, and
