ACU-1000 Operations Manual
Interoperability Now 2-75
Duplex:
The pull-down menu allows the user to configure the VOIP channel for either full or half
duplex operation.
OR Inhibit Time (ms):
The pull-down menu allows the user to configure the COR inhibit time. Six options are
available: 0ms, 500ms, 1000ms, 2000ms, 3000ms and 4000ms; 4W interface. This setting
applies to the unit’s four-wire audio interface and is included for adjustment when the module
is being used in the standalone mode. For Hybrid Mode (see the DSP Mode option setting) the
ACU Controller is the preferred method for DSP module audio interface adjustments.
COR Sense:
The pull-down menu allows the user to configure the COR sense. Three options are available:
active low, active high, and VOX. This setting applies to the unit’s four-wire audio interface
and is included for adjustment when the module is being used in the standalone mode. For
Hybrid Mode (see the DSP Mode option setting) the ACU Controller is the preferred method
for DSP module audio interface adjustments.
DSP Mode:
The pull-down menu allows the user to configure the operating mode of the DSP. Four modes
are supported (see the beginning of Section 2.15.2 for an explanation of the modes):
Mode Interfaces Used
1. Standard Mode: Rear panel four-wire & chassis backplane
2. VoIP Standalone Mode: Front panel RJ45 and rear panel four-wire connector
3. VoIP Hybrid Mode: Front panel RJ45 and chassis backplane
4. Test: test mode: for factory use only with loopback fixture.
RX Input Level:
The pull-down menu allows the user to adjust the receive input level for receive audio. Five
levels are supported: +12db, +4db, 0db, -4db, and –12db; 4W interface. This setting applies to
the unit’s four-wire audio interface and is included for adjustment when the module is being
used in the standalone mode. For Hybrid Mode (see the DSP Mode option setting) the ACU
Controller is the preferred method for DSP module audio interface adjustments.
TX Output Level:
The pull-down menu allows the user to adjust the transmit output level for transmit audio. Five
levels are supported: +12db, +4db, 0db, -4db, and –12db; 4W interface. This setting applies to
the unit’s four-wire audio interface and is included for adjustment when the module is being
used in the standalone mode. For Hybrid Mode (see the DSP Mode option setting) the ACU
Controller is the preferred method for DSP module audio interface adjustments.
