2-74 Interoperability Now
Note: Configuration options that affect the ACU rear panel D15
connector four-wire interface (for radios or other four-wire devices) are
best set by the ACU Controller, unless this isn’t possible, for example,
when the DSP module is in the Standalone mode and therefore has no
communications with a CPM module and hence the ACU Controller.
VOX Hangtime (ms):
The pull-down menu allows the user to configure the VOX hangtime in milliseconds. Five
hangtimes are available: 500ms, 1000ms, 2000ms, 3000ms, and 4000ms. VoIP or 4W

IP Address:
The user may enter numeric text (0-255 decimal) into each of the four fields that define the
unique Internet Protocol address of the unit.
Note: Upon saving the changes, the user will need to browse to the new
address to continue configuration.
Subnet Mask:
The user may enter numeric text (0-255 decimal) into each of the four fields that define the
unique Internet Protocol mask of the unit.
Note: Upon saving the changes, the user will need to browse to the new
address to continue configuration.
Gateway IP:
The user may enter numeric text (0-255 decimal) into each of the four fields that define the
gateway address that the unit will use for resolving external network accesses.
Remote IP:
The user may enter numeric text (0-255 decimal) into each of the four fields that define the
unique Internet Protocol address of the remote VoIP unit that is paired with this unit.
Remote Port:
The user may enter numeric text in this field (1-65535 decimal) defining which port to use
when connecting to its paired unit for VoIP traffic.
Voice Compression:
The pull-down menu allows the user to configure the voice compression (vocoder) that is used
for VOIP audio traffic. Five choices are available: GSM at 13Kbps, ADPCM at 16Kbps,
ADPCM at 24Kbps, ADPCM at 32Kbps, and PCM at 64Kbps. If the unit is a server,
adaptation to the incoming client vocoder is automatically selected to match the client request.
