1-2 Interoperability Now
Any individual LIS (as well as the entire wide area system) can be controlled and monitored
from any location on the network by a dispatcher using the Raytheon ACU Controller or WAIS
Controller software. The Windows-based ACU WAIS Controller provides full system control,
from the local level to statewide, or across any distance connected by an IP-based network,
allowing interoperability connections to be made between any two (or more) CSAPs by a
simple point & click procedure.
LIS – Local Interoperability System: An Interoperability System
intended to service a single political or geographical region. The basic
means of connecting the communications systems that an LIS services
are ACU-1000 audio links.
WAIS – Wide Area Interoperability System: An Interoperability System
that uses an IP-based network to provide interoperable communications
among Local Interoperability Systems and with any number of individual
users (such as system dispatchers or isolated radio systems).
Network Talkpath – An RoIP/VoIP communications link between
elements of a Wide Area Interoperability System.
RoIP
TM
– Radio over Internet Protocol: A Raytheon proprietary
protocol that uses a standard IP-based network to transfer a VoIP
channel and accompanying radio control signals including PTT, COR,
and RS-232.
1.4 Local Interoperability Via The ACU-1000
The ACU-1000 is the main building block of the Raytheon Interoperability Solution, so a basic
understanding of its operation is necessary for an overall understanding of the system.
The ACU-1000 consists of a chassis with a number of plug-in modules. The essential modules
reside at the left side of each chassis. The PSM Module is the unit’s power supply. The HSP
Module provides a local interface to the system (via a keypad, handset and speaker). It also
allows local setup and control, and houses the unit’s voice prompting circuitry. The CPM
Module controls the unit and relays status and control messages between the ACU-1000 and
either of the system control programs, the ACU Controller or the WAIS Controller.
The rest of the unit is occupied by a number of interface modules (up to 12 in a single chassis).
These modules interface the unit to the various CSAPs of the Local Interoperability System, or
provide network talkpaths to the WAIS. Different modules may be installed, depending on the
type of CSAP being interfaced. The main types are the DSP Module, which interfaces radio
systems, network talkpaths, and some types of satellite phones, and IDEN systems; next is the
PSTN Module, which interfaces telephone lines and some satellite phones or cellular phones.
Another module that may be used is the LP-2; it allows a standard telephone set to be
interfaced to the ACU-1000 so that a nearby user can communicate with the rest of the system,
wired to the LP-2 by a standard telephone cable with RJ-11 connectors.
