HYBRID BALANCE AND LEVEL SETTINGS
OVERVIEW
This feature provides the capability for remotely adjusting various hardware parameters. There are no hand-adjustable
controls on the GTI unit itself, so all adjustments must be performed from the GTI Configurator using the Balance and Levels
operation from the Comm group in the Main Menu screen.
CAUTION
It is possible to make level or gain adjustments that will reduce or increase the level or gain beyond the normal operating
range, making operation of the line unreliable or completely inoperative. You MUST know what you are doing before
performing these adjustments.
To make an adjustment, select (highlight) the
Balance and Levels
operation from the
Comm
group in the Main Menu screen,
and press the Enter key. The INDEX window in the next screen to appear will show each system in the GTI Configurator
database. Select (highlight) the desired system and press the Enter key. The STATUS window in the next screen to appear
will show the ongoing status as the GTI configurator attempts to establish contact with the selected system. Initially this
STATUS window will show the following two statements: “Connecting to system....” and “Requesting unit type...”. If the GTI
Configurator is unable to establish contact with the system, the STATUS window will show the following additional
statement: “ERROR: No response, resending pkt.”. Each time the GTI Configurator tries and fails to establish contact, the
STATUS window will show the following additional statement: “ERROR: No response, resending pkt.”. If the GTI
Configurator fails to establish contact with the system after three attempts, the STATUS window will show the following
additional statements: “ERROR: Exceeded packet retries”, “Unit never detected”, “Logically Disconnected”, and (after a
pause) “Fully Disconnected”. If the GTI Configurator establishes contact with the system, it will briefly (if you blink you will
miss it) show the following two additional statements: “CONNECTED!” and “Ready to process commands”, and then display
the Hybrid Balance Monitor screen. A sample Hybrid Balance Monitor screen is shown in Figure 11.
Hybrid Balance Monitor Screen
As soon as the GTI Configurator software displays the Hybrid Balance Monitor screen, it starts collecting the current level
and hybrid settings from each GTI unit in the system, and a lower case letter will appear in the ADJ. COMPLETED column
for each telephone line number connected to a GTI unit as that unit is checked. The Hybrid Balance Monitor screen shows the
status and type of each telephone line connected to a working GTI in the selected system.
The status of each telephone line is shown in the STATUS column. If a telephone line status changes as you look at the
Hybrid Balance Monitor screen, you will see the status change for that line. The possible status entries (and what they mean)
are as follows:
blank - line is not in service or no GTI is present for the line
BUSY - line is busy with a normal call
FREE - line is currently free (inactive)
MODEM - line is busy with an internal modem call
VOICEP - line is busy with voice prompt programming
During adjustments the Hybrid Balance Monitor screen is partially obscured by the overlay windows for the specific
adjustment. However, the Hybrid Balance Monitor screen continues to display the current status of each line and you may
notice changes in the STATUS column for the telephone line corresponding to the GTI you are adjusting. The possible status
entries you may see during adjustment (and what they mean) are as follows:
READY - line is ready, we have seized it and are on-hook
SILENCE - line is off-hook and silence number is being accessed
MILLIWAT - line is off-hook and milliwatt number is being accessed
ADJUST - we are performing an adjustment now
*ERROR* - there is something wrong with this line status
