The a/b-Audiobox is an adapter for transferring low frequency signals over an
analogue telephone line.
With the a/b-Audiobox you can connect a sound system to the internal a/b port
on a PBX, for making loudspeaker announcements from the internal tele -
phones. It also includes a switch contact with which the sound system's loud -
speaker zone can be changed.
You can install up to six switchable a/b switching modules, available as acces
-
sories, between the PBX and a/b-Audiobox to implement additional switching
functions.
The a/b-Audiobox can be combined with all Auerswald PBXs, providing a way
to connect analogue DTMF telephones. It is also possible to connect it to PBXs
from other manufacturers, but you should verify this in advance, by checking
with the specialist supplier or the manufacturer.
You can program the a/b-Audiobox from a telephone on the PBX, and so con
-
figure it to meet the special needs of the particular environment.
The a/b-Audiobox is only suitable for use indoors.
