Configuring the TLE
Using the Configuration Software, different configurations can be saved to download to
the TLE. A configuration contains all the programmable parameters of the TLE. The
standard TLE (TLE-BASE) unit can have 2 different configurations, while the add-on
software modules can have up to 16 different configurations.
The Active Configuration is the configuration that is being used by the TLE. Any
configuration may be selected as the Active Configuration using the Configuration
Software, or an ASCII command string via the serial port, or a DTMF dialing sequence
from a device connected to a port. See below for more information.
A Configuration Set is a file name given to reference the configurations saved. Only one
Configuration Set can be downloaded to the TLE, although multiple Configuration Sets
can be saved on the PC.
Editing a configuration may be done off-line, or while connected to the TLE. While
connected to the TLE, changes made are updated in the TLE by either selecting the
APPLY or OK button on each screen. Using the APPLY button will implement the
changes but keep the current screen to allow for any additional changes. Using the OK
button will implement the changes, exit the screen and return to the Main screen. If the
update is to the Active Configuration, every update will cause the display of the TLE to
show “Initializing Configuration” and then “Active Configuration” and then the configuration
number. The TLE must be in the idle state (all lines on-hook) for the update to occur. If
the update is to a configuration that is not currently active, the TLE display will not change.
When the TLE_PC software is run, it will read the Unit Name and the Active
Configuration of the TLE and display them on the Main screen of the software. If there is
no TLE connected, the title bar will read TLE_PC - No Unit Connected. If there is a TLE
connected and the Configuration of the TLE does not match the default configurations in
the software, a screen will appear asking whether you want to query the TLE for its
configuration settings. In addition, any time the TLE is initially connected, the software
will automatically query the unit for firmware version information. If the software has an
updated version, it will ask you if you want to download the new code.
Reset
On the front panel of the TLE there is a recessed button called Reset. Pressing this
button for greater than 1 second once will display a prompt asking. “Reset all configs?
Press Reset = yes”. Pressing Reset a second time for greater than 1 second will reset the
TLE configuration memory to the factory default settings with Configuration 1 active.
When the front panel Reset button is pressed, the unit will be reset to the US/Canada
defaults for all configurations. The user must perform Defaults and Send All from the PC
configuration software to reload the defaults for each individual country configuration.
Selecting Active Configuration using DTMF
All other ports must be on-hook and the dialing sequence is as follow: go off-hook, dial
∗∗99## to enter Programming Mode, then dial ∗xx#, where xx is the configuration
number. For example, to select configuration 02, dial ∗02# and the TLE will respond with
