Configuration of TX Level (TLP)

The FXS+ option module executes an abbreviated self
test during the power up sequence, as described in the
TSU 100/600 manual. No initialization input is
required. Any previously configured setting for the
FXS+ is restored automatically upon power up.
The green OK LED, located with the Module LEDs on
the front panel, illuminates when a successful self test is
completed and the configuration is successfully restored.
See the section Front Panel Operation in the TSU 100/600
User Manual.
If the FXS+ module fails one or more of the self tests a
message is displayed in the LCD during power up. See
TSU 100/600 User Manual. Specific failures of the FXS+
module are identified in the appendix FXS+ Failure
Messages in this manual.
The red ALARM LED with the Module LEDs on the front
panel illuminates when an alarm condition is detected.
For any installation where the analog channel (DS0)
terminates within the Public Switched Telephone
Network, the TX LVL should be set to +3 dBm. For
point-to-point applications where the channel terminates
in other customer equipment, any TX LVL may be used.
A +3 dBm TLP setting attenuates the analog signal
by 3 dB.
