E1 Input Module Event Reporting - Symmetricom SSU-2000 User Manual

Chapter 7 Input Module Reference Data
1-Port and 3-Port E1 Input Modules
User can select high or low logic level as alarmed
If the hardware indicates that the cesium fault level matches the alarmed setting,
log an AIS alarm against port 1
Clear the alarm when the hardware's cesium fault level no longer matches the
alarmed level
Input Measurement Problems
If the MTIE values for a selected clock exceed either of the MTIE masks, the Input
module takes appropriate action according to the severity level associated with the
MTIE alarms.
If a received SSM has a lower PQL than the provisioned value assigned to the port
and the port has SSMs enabled, the Input module performs the action required by
the alarm mode.
