RAD Data comm Modular Access Device with Integrated Router, E1/T1 Ring Detection to E1 on

FCD-IPMInstallation and Operation Manual		Chapter 5 Setup Menu
A bit inverted When the received A bit signal from E1 equals 1 then on hook will be
	indicated in the FXO interface
	When the received A bit signal from E1 equals 0 then off hook will be
	indicated in the FXO interface
B bit	When the received B bit signal from E1 equals 1 then off hook will be
	indicated in the FXO interface

When the received B bit signal from E1 equals 0 then on hook will be indicated in the FXO interface

B bit inverted When the received B bit signal from E1 equals 1 then on hook will be indicated in the FXO interface

When the received B bit signal from E1 equals 0 then off hook will be indicated in the FXO interface.

Ring Detection to E1 on

Select this parameter to specify the ring detection signaling transmission mode from FXO towards E1. The values are:

A bit	For ring detection the A bit signaling will be set to 1 towards E1
	For no ring detection the A bit signaling will be set to 0 towards E1

A bit inverted For ring detection the A bit signaling will be set to 0 towards E1

	For no ring detection the A bit signaling will be set to 1 towards E1
B bit	For ring detection the B bit signaling will be set to 1 towards E1
	For no ring detection the B bit signaling will be set to 0 towards E1

B bit inverted For ring detection the B bit signaling will be set to 0 towards E1

For no ring detection the B bit signaling will be set to 1 towards E1.

Default ABCD to the E1

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 E1.

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

When polarity is configured as Enabled, the polarity signal is received from E1 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).

Signaling Feedback

This parameter is set to:

Enabled	feedback of the on/off hook signaling that was received from E1 is
	transmitted back to E1
Disabled	feedback of the on/off hook signaling that was received from E1 is not
	transmitted back to E1.

Out of Service Method

This parameter specifies the on/off hook signaling in FXO when an Out of Service condition is indicated in the E1 link. The values are:
