On/off hook from the T1 On

Select this parameter to specify the receive mode for on/off hook signaling from T1 into FXO. The values are:

A bit	When the received A bit signal from T1 equals 1 then off hook will be
	indicated in the FXO interface
	When the received A bit signal from T1 equals 0 then on hook will be
	indicated in the FXO interface

A bit inverted When the received A bit signal from T1 equals 1 then on hook will be

	indicated in the FXO interface
	When the received A bit signal from T1 equals 0 then off hook will be
	indicated in the FXO interface
B bit	When the received B bit signal from T1 equals 1 then off hook will be
	indicated in the FXO interface
	When the received B bit signal from T1 equals 0 then on hook will be
	indicated in the FXO interface

B bit inverted When the received B bit signal from T1 equals 1 then on hook will be indicated in the FXO interface

When the received B bit signal from T1 equals 0 then off hook will be indicated in the FXO interface.

Ring Detection to T1 On

Select this parameter to specify the ring detection signaling transmission mode from FXO towards T1. The values are:

A bit	For ring detection the A bit signaling will be set to 1 towards T1
	For no ring detection the A bit signaling will be set to 0 towards T1

A bit inverted For ring detection the A bit signaling will be set to 0 towards T1

	For no ring detection the A bit signaling will be set to 1 towards T1
B bit	For ring detection the B bit signaling will be set to 1 towards T1
	For no ring detection the B bit signaling will be set to 0 towards T1

B bit inverted For ring detection the B bit signaling will be set to 0 towards T1

For no ring detection the B bit signaling will be set to 1 towards T1.

Default ABCD to the T1

This parameter specifies the default signaling bits that are not used for ring detection or for polarity (if Enabled). Those bits will be transmitted towards T1.

Polarity (polarity reversal, also known as Wink Start Reversal)

When polarity is configured as Enabled, the polarity signal is received from T1 either on the B bit (while the on/off hook from T1/E1 parameter is configured to

A bit or A bit inverted), or on the A bit (while the on/off hook from T1/E1 parameter is configured to B bit or B bit inverted).
