MTI DOC 91743-A1
FEATURES
The 91743 digital amplifier provides all of the standard features of any IP-based intercom
system. These features include, but are not limited to the following set:
1.
TCP/IP based digital transmission of all audio communications between master stations
(touchscreen computers) and the amplifier via g.711 digital audio encoding.
2.
A single digital amplifier, along with use of MTI 81129 or 81229 termination boards, can
support any number of intercom stations.
3.
The system can be utilized to meet any number of configuration requirements. The
standard configuration method is to utilize 81129/229 intercom termination boards for
switching the analog input/output between the digital amplifier and a set of intercom staff
stations. If desired, the digital amplifier can be used in a 1:1 configuration, in which one
digital amplifier directly connects to a single staff station, providing a fully digital system
to the staff station.
4.
Communications to and from the 91743 can be managed through a standard Microsoft
Windows-based computer with PC sound card, or via a separate handset master station
connected through the computer.
5.
The mounting hardware provided with the 91743 and supporting components allows for
simple installation under most configurations, including cabinet or rack mounting (with
use of a backplate).
6.
With the use of the MTI ProDesign suite, stations can be assigned labels based on an
alpha-numeric numbering system. This allows the designer to assign station
names/numbers based on a numbering system or a text-based naming system.
7.
With the use of the MTI ProVision application, the intercom system can provide master-
to-master calling and/or master-to-station calling.
8.
Call indication can be activated through a number of inputs, including:
a.
Call station push button
b.
Auxiliary input such as a card access system or other indication.
c.
Audio Level (Scream alarm).
9.
Call management can be governed by standard Push-To-Talk (PTT) control via the
ProVision application, or through VOX still “ambient noise” control. For detention
facilities, MTI recommends the use of the PTT feature so that the operator has full
control over the flow of the conversation.
10.
With the use of the ProVision application, the operator has the option to “protect” any
intercom. Through this feature, the operator can enter a sort of “privacy” mode, in which
the operator will only receive call-ins that are tagged as alarm points (such as audio level
alerts).
11.
The intercom system can be programmed to handle any number of paging zones,
depending on the intercom system configuration.
12.
The system can provide group paging capabilities, in which a single group page can be
initiated from any associated master station.
13.
Multiple paging zones can be activated through an “All-Call” button, or through a group
paging icon.
