Activates 2W (FXS) tests on a per-port basis. Options include OFF, ACTIVE, TIP OPEN, REV. BATTERY,

DISABLED, and RINGING. The 2W tests will disrupt the active call on the selected FXS port. Table 3 displays the state of the 2W conductors during each test.

Table 3. FXS 2W State Table

TEST	TIP OUTPUT	RING OUTPUT
Off	No test active	No test active
Active	Ground	Supervision voltage
Tip Open	High impedance	Supervision voltage
Rev. Battery	Supervision voltage	Ground
Disabled*	High impedance	High impedance
Ringing	Ringing voltage	Ringing voltage

* Disables the output of the FXS port; it does not disable the test.
