1.4.1.3 Multiple Cross-Connections
The ACU-1000 is not limited to one-to-one conversations. Cross-connections can be made that
create a large conference call with multiple users. This could include several different radio
systems, a caller on a telephone line, a satphone or IDEN user, and a system operator using a
dispatch console. All of these different users will be able to converse with each other.
These multiple cross-connections can take place either at the local level (up to 8 simultaneous
two-way conversations within any ACU-1000) or over the wide area network (where the only
limit is practical… how many people can engage in an effective conversation at the same time).
1.4.1.4 Monitor Connections
Any ACU-1000 module can be set to monitor any other module in that ACU-1000. When
module A monitors module B, it hears any receive audio coming into module B from an
outside source. However, module A does not send any audio to module B or otherwise affect
its operation.
1.5 Wide Area Interoperability
It is possible to connect individual ACU-1000’s together to form a “wide area” system that
might typically be a regional or statewide system. These systems are useful for coordinating
communications during a “moving” event such as a car chase or ambulance transport that
crosses through multiple jurisdictions and/or communications systems. Hurricanes, floods, and
tornados typically can produce widespread damage over multi-county areas. A wide area
regional or statewide system can be beneficial in coordinating all of the different agencies that
are typically involved in managing disasters of this magnitude.
Wide area interoperability is made simple thru the use of WAIS Controller software running on
a PC at each desired control point and an IP infrastructure that allows all the ACU-1000 and
other system components to be interconnected in a logical and controlled manner. It is
important to keep in mind that during a disaster, IP infrastructure could be affected and backup
connectivity and routing methods should be considered. The WAIS Controller software
manages the IP network talkpaths that allow the most efficient use of resources in creating the
necessary area-to-area talkpaths.
1.6 Module Descriptions
1.6.1 General
The ACU-1000 system is a modular interface/interconnect system packaged in a Eurocard
chassis. With this product, an intelligent interconnect system can be configured to meet almost
any interface application involving telephones and radios of any sort. The ACU-1000 system is
suitable for HF, LMR, Satcom systems, IDEN systems, Landline PSTN systems, and Cellular
Telephone systems and offers essentially unlimited applications and expandability. An ACU-
1000 Local Interoperability System consists of a chassis, backplane and modules, module
software, and system control software.
