1.8
Control Methodology
The unit may be controlled (create and dissolve cross-connections between the devices interfaced
to the unit) in two ways:
o
Via a web-based graphical user interface that allows users to create interoperability nets
by simple mouse-click procedures.
o
Via user-initiated DTMF sequences.
Section 6 provides details about both control methodologies.
1.9
Expansion Capability
The communications capabilities of the system can be expanded by connecting two units together
over an Ethernet connection. One unit is then configured as the “Master” and a system operator
can view, configure, and operate the dual system through the Master unit. The expanded system
will allow interoperability nets with up to 24 channels (plus one handset connected to the Master
Unit).
Note: The two units connected to create a 24 channel “expanded” system must be connected
either directly by CAT-5 cable or be on a common LAN (no router intervening).
1.10
Connection to Other Radio Gateways
Connection to other ACU-5000s (beyond the two unit expanded system explained above) or
inter-operation with any other radio gateway devices can be accomplished via the NIST standard
BSI interface protocol (Bridging Systems Interface). Links can be made to any other BSI
compliant gateways (for example an ACU-2000 or another ACU-5000). The ACU-5000
currently supports inclusion in an ACU-1000/ACU-2000 based WAIS (Wide Area
Interoperability System), however there are no provisions to dispatch to radios interfaced to the
ACU-5000 (a feature of WAIS Enhanced and WAIS Enterprise).
The Bridging Systems Interface is a specification jointly developed by government and industry
that defines an industry-standard interface for communications between radio interoperability
systems. The BSI is based on SIP and RTP and allows the radio nets of disparate interoperability
systems to be bridged together.
1.11
SIP Instructions
This manual does not attempt to familiarize the reader with SIP fundamentals. SIP is an open
protocol and there are many references that explain how to best make use of it.
