Alcatel-Lucent 1643 AMS - Parameters for Configuring PM on the ITM-CIT

Parameters for configuring PM on the ITM-CIT
...................................................................................................................................................................................................................................
AU4
Layer of a connection termination point. This list is populated with AU4s if the
selected PM Point Type is VC4 (VC-4-4c, VC-4-16c), AU4, TU12, TU2, or TU3. In
all other cases this field is greyed out.
BBE
A Background Block Error (BBE) is an errored block not occurring as part of a
Severely Errored Second (SES).
Default
Restores the installation TR and RTR default values for each performance parameters
of the selected termination point. Greyed out when the Enable Thresholding is
unchecked.
Enable counters
Enables/disables the digital counters linked to the active Tab (either 15 Minutes, 24
Hours, or Bidir 24 hr) and selected termination point.
Enable thresholding
Enables/disables thresholding for the monitored parameters of the selected Performance
Monitoring point linked to the active Tab. This check box is greyed out if the Enable
counters is unchecked.
When Enable Thresholding is changed from disable to enable the value of the TR and
RTR is retrieved from the NE. If the value is not available because the termination
point is newly created, then the system default value is retrieved.
EB
A block is regarded as Errored Block (EB) if that block does have one or more errors.
This is determined by the comparing the outcome of the BIP check done before and
after transmission. The number of blocks per second depends on the signal itself. A
VC-12 does have 2000 blocks per second while an STM-N does have 8000 blocks per
second.
ES
A second is regarded as Errored Second (ES) if this second has one or more blocks in
error.
Termination point
Final destination where an incoming signal is terminated in the NE.
