3.6.4 Power-up the ATA
Insert the Plugpack connector into the 12VDC socket on the ATA back panel.
Whilst pressing and holding the RST button at the back of the ATA, turn the 240V power
on at the power point. Release the RST button when the display changes to a “C”.
3.6.5 Adjust the Display Orientation of the ATA
The ATA starts with a “C” displayed (for “cold boot”) then progresses to the “Display
Orientation Mode” and you have 3 seconds to press the RST button to change the display
orientation if the unit is wall mounted. An upright “U” symbol indicates correct display
orientation. Mounted on a wall the display should be inverted so the numbers appear in
the correct orientation.
3.6.6 Select the Required TEI Number
After the “Display Orientation Mode” the ATA goes into the “TEI Setting Mode”. The
default TEI is 63 when an ATA is installed for the first time. First, the current TEI is
displayed. Then you have the opportunity to change the TEI if needed. “H” will be
initially displayed indicating the ‘most significant digit’ (MSD) followed by the current
MSD with a decimal point. This is displayed for three seconds during which time the
number can be changed. Then an “L” is displayed followed by the ‘least significant digit’
(LSD) with no decimal point for the next three seconds.
If the TEI number needs to be changed, use the RST button to step through the numbers
to set the required MSD, while the MSD is displayed. Similarly, step through the numbers
for the LSD until the required number is selected. The ATA will then flash the new TEI
and exit the TEI mode.
Another method of setting the TEI is to use a phone on the POTS port and enter
#6#<TEI>#, where <TEI> is the number required (e.g. to program a TEI of 63 press
#6#63#).
3.6.7 Observe D-Channel X.25 Call Progress For the First Call
After exiting the “TEI Numbering Mode” the ATA performs self-test and other internal
functions which take about 90 seconds to complete. Activity during this phase is
indicated by a display of three rising bars. It then automatically makes a D-Channel X.25
call to the factory programmed Argent Pre-configuration NMS number to obtain its IP
address and the X.121 and IP addresses of the main NMS application hosts. During this
process the Seven-Segment Display shows a 3, “Pre-Configuration in Progress”. If for
some reason the ATA is unable to establish an X.25 connection or the connection is
terminated with a non-zero error code (Cause/Diagnostic code), the display will show a
flashing 6 (Last call attempt failed, D-Channel).
3.6.8 Observe D-Channel X.25 call Progress For the Second Call
