A Law Coding for E1 links
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.
