E/LZB 119 1889 R1A INTRODUCTION / DESCRIPTION

ENHANCED FEATURES

A site containing GETCs with Enhanced Features

enabled (using Release 6 or later software), and a SIM

(using Release 1 application software) that is connected to a

System Manager (using Release 6 or later software), has the

following features in addition to the standard features

offered by a Basic EDACS or SCAT site.

Dynamic Site Reconfiguration

Parameters for the following trunking features may be

reconfigured remotely through the System Manager when

needed, without disrupting service on the system:

• Unit Enable / Disable by LID - The Unit Enable /

Disable feature allows the System Manager to

remotely enable or disable individual radio units.

• Validation by GID - The GID validation feature

allows the site to deny call requests to GIDs not

defined in the database. GIDs may be added or

deleted from the database by the System Manager.

• Priority Queuing by GID - The priority queuing

feature allows the site to assign queued calls to

available channels using a system of priorities. The

priority for each call type (Voice, Data, and Digital

Voice) for each defined GID may be reconfigured

by the System Manager.

• Message Trunking by GID - GIDs with a Hang

Time greater than 0 are message trunked (the same

channel will be used for each transmission). The

Hang Time for each GID may be reconfigured by

the System Manager. (This feature is not supported

in a SCAT site.)

• Confirmed Call by GID - The confirmed call

feature allows the site to assign each radio logged

into that GID to a Working Channel before the

caller is allowed to talk. This feature may be

enabled or disabled for each GID by the System

Manager. (This feature is not supported in a SCAT

site.)

Monitoring & Reporting

Alarm Reporting

The SIM reports the following alarms to the System

Manager:

• Poll Alarm - Indicates that poll responses from a

Working Channel or Downlink GETC are not

being received by the Control Channel GETC).

• Carrier Alarm - Indicates the presence of an RF

carrier without proper signaling (possible

interfering signal or deliberate jamming).

• Auxiliary Alarm - Indicates the detection of a Test

Unit alarm by the TUAI at a Simulcast transmitter

site.

• Phone Alarm - Indicates the absence of data from a

Voter in Voted or Simulcast System (possible line

noise or breakage on link from Voter to GETC).

• MASTR III PA Failure Alarm - Indicates that a

specific repeater’s output power has dropped below

the threshold level. (Note: See System

Requirements for upgrading sites.)

• Voter Alarm - Indicates that error messages are

being received by GETC from Voter.

• MASTR III Synthesizer Unlock Alarm - Indicates

that a specific repeater’s synthesizer is not locked.

(See System Requirements for upgrading sites.)

• GETC Turbo Board Failure Alarm - Indicates a

disruption in communication between a specific

GETC’s main processor and Turbo Board.

• BSL Failure Alarm - Indicates that no polling

message has been received (by the SIM) from the

Control Channel GETC for 15 seconds.

Site Activity Monitoring

Alarm and trunking activity at the site may be

monitored in real time on the System Manager’s Alarm

Display and Acknowledge screen, and Site Monitor screen.

Activity Records

Activity records for alarm and trunking activity at the

site are periodically sent to the System Manager for use in

making reports.
