1.6.8 LP-2 Module
The Local Phone Module is the interface to the ACU system for 2-wire devices (such as a
telephone set), which generate dialing information. This module contains a loop current
generator, ring voltage generator, dial and busy tone generators, a DSP hybrid with VOX and a
DTMF generator/receiver. The LP-2 is typically used to create a local interface to the system
that is located nearby but not directly at the ACU-1000. A system operator alongside the ACU-
1000 would use the HSP-2A handset and keypad. A system operator a short distance away
could use the handset and keypad of a telephone set cabled to an LP-2 module by a standard
telephone cord. In addition to interfacing a telephone set into the ACU system, this module can
be used as a telephone "line card" in a mini-PBX system.
1.7 Related Equipment
This section introduces other equipment that can be used in conjunction with the ACU-1000 to
monitor and control the unit, or to extend its range to an IP based network. Also described is
the ACU-T, a version of the ACU-1000 in a Tactical Package.
1.7.1 ACU Controller
The ACU-Controller provides an intuitive Graphical User Interface for easy control of an
ACU-1000 or ACU-T. The main screen, shown in Figure 1-5, provides a clear overview of
current system status with icons to identify the various system components.
Cross-connections are made and dissolved by simple point-and-click procedures. Other
features include the ability to store specific system configurations for later recall, a log file of
system activity, and the ability for both local and remote (via an IP-based network) control.
