Transmission Interface Handling DS1 1544 kbit/s
54.3.5 Administration
Supervision of transmission faults and transmission quality can be
performed in different ways. With the help of parameters, the
supervision can be configured to meet a wide range of requirements.
The configuration parameters can only be changed when the AO DP is
in state "Disable". The parameters of interest are given below.

The parameters P and Q
−
The parameters P and Q are used for defining unavailable
state
−
Value range is 5-15 s
−
Default value is 10 s
The parameter N1
−
The parameter N1 defines the threshold numbers for SES.
Value range is 1-1000
−
Default value is 320
The configuration parameter T
−
The parameter T defines the time interval for ERATE
supervision
−
Value range is 1-5 s
−
Default value is 2 s
The configuration parameter AFT
−
The configuration parameter AFT defines the Alarm
Filtering Time for all the fault supervision functions
except RAI supervision
−
Value range is 50-5000 ms
−
Default value is 125 ms
−
The resolution is 1 ms, but the accuracy is ±25 ms
The configuration parameter AFT RAI
−
The configuration parameter AFT RAI defines the Alarm
Filtering Time for the fault supervision function RAI
supervision
−
Value range is 50-5000 ms
−
Default value is 125 ms
−
The resolution is 1 ms, but the accuracy is ±25 ms
Base interval for ES, SES, UAS, BFF and SF
−
Valid values: 60 and 126 seconds. The value 126
seconds must be used when BFF supervision is activated
in the BSC.
