E signal from the E1 on

Select this parameter to specify the E signal receive mode from E1 into E&M. The values are:

A bit	When the received A bit signal from E1 equals 1 then the E signal will be
	activated in the E&M interface
	When the received A bit signal from E1 equals 0 then the E signal will be
	inactivated in the E&M interface

A bit inverted When the received A bit signal from E1 equals 0 then the E signal will be

	activated in the E&M interface
	When the received A bit signal from E1 equals 1 then the E signal will be
	inactivated in the E&M interface
B bit	When the received B bit signal from E1 equals 1 then the E signal will be
	activated in the E&M interface
	When the received B bit signal from E1 equals 0 then the E signal will be
	inactivated in the E&M interface

B bit inverted When the received B bit signal from E1 equals 0 then the E signal will be activated in the E&M interface

When the received B bit signal from E1 equals 1 then the E signal will be inactivated in the E&M interface.

Default ABCD to the E1

This parameter specifies the default signaling bits that are not used for the

M signal. Those bits will be transmitted towards E1.

Out of Service Method

This parameter specifies the E signaling state in E&M when an Out of Service condition is indicated in the E1 link. The values are:

Forced Idle E1 signal is held at inactive for the duration of the Out of Service condition Forced Busy E1 signal is held at active for the duration of the Out of Service condition

Idle Busy E1 signal is held at inactive for 2.5 seconds, and then toggled to active until the Out of Service condition end

Busy Idle E1 signal is held at active for 2.5 seconds, and then toggled to inactive until the Out of Service condition end.
