CEC/IMC PERSONALITY
CONFIGURATION
At the System Manager (refer to LBI-38984), configure
the CNI groups as TRACKED. This enables the CEC/IMC
to route only Wide Area Group Calls to the CNI GETC
corresponding to the last conventional CNI transmission.
Also use the System Manager to set up the Logical ID’s for
the conventional repeaters. These ID’s must be valid on the
trunked systems for patching and should be the same ID’s
set in the GETC Personality during the CNI GETC
Personality Programming.
Configuring the CNI as Forced in the CEC/IMC’s
Personality will result in the CNI receiving Wide Area
Group Calls, regardless of the last call on the repeater.
Remember, the CNI responds only to the Group ID’s
configured in the CNI’s Personality.
A site must be set up in the CEC/IMC using the
CEC/IMC Manager (MOM PC). It needs one (1) slot for
CNI. Audio Board 1, Channel 1 should be used. We also
recommend that CNI Systems not be Confirmed. Refer to
LBI-39024.
The CEC/IMC bypasses the CNI system with other
multisite calls making the CNI channel available for users
within the CNI system coverage area for System Manager
programming.
LED INDICATORS
The CNI’s front panel LEDs indicate the CNI’s
operational state (refer to Table 3). Upon power up, L1
turns ON indicating proper CNI operation. For Narrow
Band CNI GETC’s, L3 also turns ON. These LED’s will
continue to remain ON.
When a conventional radio transmission with valid
Channel Guard tone information is initiated, L6 also
illuminates.
When the CNI GETC receives a valid Group Call
Channel Request from the CEC/IMC’s Uplink GETC,
LED’s L2 and L6 illuminate.
TEST AND ALIGNMENT
This section provides instructions for performing a
functional checkout of the CNI GETC and repeater using
radios programmed for CNI operation.
In the event the repeater requires minor adjustments, this
section also provides supplemental information for setting
up MASTR II, IIe, or III repeaters for CNI operation.
FUNCTIONAL CHECKOUT
Verify the proper installation of the CNI software by
reading the GETC’s coded LED display.
Look for normal operation while placing several test
calls. Test the system’s fault tolerance by keying a radio
then turning the radio power off without releasing the PTT
switch. The channel should drop the call and return to an
idle state within two to three seconds.
Locally Initiated Call
This procedure assumes that the test radios being used
have their personalities set to the proper Channel Guard
tones and are operating in the conventional mode.
1. Cycle power the repeater (or reset the GETC). The
repeater should default to the Idle State.
