2.15.2 DSP Configuration Programming via Browser
This section addresses the configuration of the features enabled by the module’s Ethernet port.
Either of three operating modes may be selected. The DSP module can use any two of its three
interfaces, and the interface selection determines the operating mode.
The interfaces are:
• Front panel RJ45 Ethernet connector
• Rear panel four-wire interface (15-pin D-sub connector to radios or other devices)
• Chassis backplane for CPM control and for connections with other modules
The operating modes are that these interfaces can produce are
• Standard Mode: Rear panel four-wire & chassis backplane
• VoIP Standalone Mode: Front panel RJ45 and rear panel four-wire connector
• VoIP Hybrid Mode: Front panel RJ45 and chassis backplane
The VoIP features of the two VoIP modes are configured by browsing to the front panel RJ45
connector. The non-VoIP features of all modes are set either by browsing to the RJ45 or via the
ACU Controller. Please note that once a unit is configured by a browser to VoIP Standalone
Mode, it can no longer communicate with the CPM module or the ACU Controller. The ACU
Controller includes various features (such as a library of stored radio configuration templates)
that assist with optimizing the four-wire interface, so the ACU Controller is the recommended
setup method for this interface.
See 2.15.3 for minor variations in programming the DSP-3 module, which allows VoIP
communications with a WAIS Controller 2 operator in conjunction with the Standard Mode
operation.
2.15.2.1 Standard Mode
When in the Standard mode, the DSP module cross-connects audio and control signals from
radios to other modules in the local ACU system via the chassis backplane. It’s still possible to
browse to the module via its front panel RJ-45 Ethernet port, but there is no VoIP capability. A
more precise explanation includes the facts that:
• The local ACU system includes any modules of an Expansion Chassis
• Besides its primary function as a radio interface, the DSP module will interface any
type of four-wire device
2.15.2.2 VoIP Standalone Mode
This mode allows the DSP module to act as an independent, standalone, network-to-radio
interface. The ACU chassis provide a rear panel radio connector and power & ground signals to
the module but has no other interactions with it. In this mode, the DSP will be ignored by the
ACU Controller and WAIS Controller programs, as well as by the CPM module and any other
modules in the ACU chassis. The module’s Ethernet connector allows VOIP connections to
other network-capable devices on the network that use the JPS RoIP protocol. These devices
include other DSP modules, CPM modules, NXU-2A units, as well as PCs running the PCNXU
