FXO+ Dual Voice Option Module User Manual 61200.103L2-1
INSTALLING THE FXO+ DUAL VOICE OPTION MODULE
For ease of replacement, power to the TSU 100/120/
600 may be
on when installing or removing the FXO+
Dual Voice option module.
For use in Canada, regulatory compliance requires that the
Transmit Level/Transmit Level Point, TX LVL (TLP), of the
FXO+ Dual Voice option module be set to a value between
+3dB and +8dB inclusive, and that the TSU 100/120/600
be password protected to prevent unauthorized alteration of
the level.
See the chapter Operations for information on setting the
Transmit Level/Transmit Level Point, TX LVL (TLP). See
the TSU 100/120/600 user manual for information about
password protecting the unit.
