Transmission Interface Handling G.703 2048 kbit/s
The number of unavailable seconds for each direction is reported after
each BI.
53.3.5 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 configuration parameter N
−
Defines the threshold number (SES) for commence, and
cease, of CSES
−
Value range is 5-60
−
Default value is 10
The parameters P and Q
−
Used for defining unavailable state
−
Value range is 5-15 s
−
Default value is 10 s
The parameters N1 and N4
−
Define the threshold numbers for ES and SES. Value
range and default values are listed below:
Parameters N1-N4
Value Range

28 1-100
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
−
Value range is 50-5000 ms
−
Default value is 125 ms
