software. The DSP in Standalone Mode functions exactly like an NXU unit, and multiple
NXU-2 units may be replaced by multiple DPSs in Standalone Mode.

NXU-2A, information and free downloads (including the full NXU-2A

2.15.2.3 VoIP Hybrid Mode
This mode allows the DSP to function as an RoIP interface to the ACU backplane, allowing
remote cross-connection to take place over an IP network. In this mode, the DSP is visible to
the ACU’s CPM module and the ACU Controller and WAIS Controller software. There is no
connection to the associated rear panel D15 four-wire connector, as the DSP module’s two
operating interfaces in this mode are the front panel RJ-45 and the chassis backplane.
2.15.2.4 Provisioning
As shipped from the factory, the default configuration of the DSP is Standard mode, and no
network provisioning is required. When used in either the VoIP Standalone or VoIP Hybrid
modes, the DSP must be configured for VOIP operations. Configuration is accomplished via
PC / Browser / Ethernet web access. Configuration is best done using the ACU Controller
Software; most of the DSP module’s configuration options in the Standard mode are not
accessible via the browser interface.
To activate either of the two VoIP modes, first connect the DSP to an Ethernet LAN via the
front panel RJ-45 Ethernet connector. Use a “straight-through” CAT5 Ethernet cable to a
switch or router which is also connected to a PC with network access to the same switch or
router.
The user must browse (using a web browser such as Internet Explorer) to the DSP module’s IP
address. The default address as shipped from the factory is 192.168.1.200. (After
provisioning, this IP address may be changed to suit user requirements).
A direct connection between a PC and the module may be used when:
• A CAT 5 crossover cable is used rather than a straight-through cable
• The PC is preconfigured with a static IP address
