OPERATION AE/LZB 119 1889 R1

Confirmed Call by GID

The GETC uses the Confirmed Call Enable parameter

in the GID database to determine if a group call must be

confirmed before the caller is given channel access (allowed

to talk). This parameter is reconfigurable for each defined

GID (see System Manager screen 12, panel 3). Enabling the

Confirmed Call parameter, for a GID that is not Wide-Area

enabled, ensures that all radios logged into the group have

tuned to the assigned channel before the caller is given

channel access (allowed to talk). Enabling the Confirmed

Call parameter, for a GID that is Wide-Area enabled,

ensures that at least one radio logged into the group at each

site is tuned to the assigned channel before the caller is

given channel access (allowed to talk). Y is for enable; N is

for disable. The System Manager default is N. (This feature

is not supported in a SCAT site.)

Monitoring & Reporting

The following alarm and trunking activity features are

available remotely through the System Manager:

• Alarm Reporting

• Site Activity Monitoring

• Activity Records

Alarm Reporting

The SIM reports the state of the following alarms to the

System Manager whenever an alarm changes state, or

whenever requested to do so by the System Manager.

(These alarms can also be shown on the top line of the SIM

display - see Programming section in this manual). The

System Manager then displays the state of these alarms on

screen 40 (names underlined are as shown on screen 40).

However (unlike the operation of the site under the direction

of a Site Controller), only the Power, Synth, Poll, and Turbo

alarms are used to fail channels.

• Auxil (System Manager screen 40) - Indicates the

detection of a Test Unit alarm by the TUAI at a

Simulcast transmitter site - state changes are

reported (by Control Point GETC for that channel)

to SIM over BSL - SIM sends Auxil Alarm to

System Manager (but channel is not failed).

• Carrier (System Manager screen 40) - Indicates the

presence of an RF carrier without proper signaling

(possible interfering signal or deliberate jamming) -

state changes are reported to SIM over BSL - SIM

sends Carrier Alarm to System Manager (but

channel is not failed).

• Power (System Manager screen 40) - Indicates that

MASTR III repeater’s output power has dropped

below threshold level - state changes are reported

by GETC to SIM over BSL - SIM marks channel as

failed and sends Power Alarm to System Manager -

first supported by GETC Release 6, Site Controller

Release 7, and System Manager Release 6. (See

System Requirements to upgrade sites.)

• Synth (System Manager screen 40) - Indicates that

MASTR III repeater’s synthesizer is not locked -

state changes are reported to SIM over BSL - SIM

marks channel as failed and sends Synth Alarm to

System Manager - first supported by GETC

Release 6, Site Controller Release 7, and System

Manager Release 6. (See System Requirements to

upgrade sites.)

• Voter (System Manager screen 40) - Indicates that

error messages are being received by GETC from

Voter - state changes are reported by GETC to SIM

over BSL - SIM sends Voter Alarm to System

Manager (but channel is not failed) - first supported

by GETC Release 6, Site Controller Release 7, and

System Manager Release 6.

• Phone (System Manager screen 40) - Indicates the

absence of data from a Voter in Voted or Simulcast

Systems at the GETC’s Rockwell Modem 9600

baud synchronous serial port (possible line noise or

breakage on link from Voter to GETC) - state

changes are reported to SIM over BSL - SIM sends

Phone Alarm to System Manager (but channel is

not failed).

• Poll (System Manager screen 40) - Indicates that a

Working Channel or Downlink GETC is not

responding to polling messages from the Control

Channel GETC (or responses are not being

received by the Control Channel GETC) - state

changes are reported to SIM over BSL - SIM marks

channel or downlink as failed and sends Poll Alarm

to System Manager.

• Turbo (System Manager screen 40) - Indicates a

disruption in communication between the main

GETC processor and its Turbo Board - state

changes are reported to SIM over BSL - SIM

marks channel as failed and sends Turbo Alarm to

System Manager - first supported by GETC

Release 6, Site Controller Release 7, and System

Manager Release 6.
