than 10
-3
.
• Data Alarm :
• if the tributary is not currently used for traffic, then it is necessary to configure it as inverted
(I). In this mode, there will be no tributary alarm for this particular tributary if it is not
connected. However, if this tributary is connected while being in "I" position, a tributary
alarm is generated.
• If the tributary is used for traffic, it is necessary to configure it as normal "N". In this mode
