Remarks
If no timeslot range is specified, all
timeslots are bundled into one
channel set.
The default timeslot speed is 64
kbps, and the default T1-F interface
speed is 1536 kbps.
Optional.
The long 0db keyword applies by
default.
Optional.
The default is B8ZS.
Optional.
The default is slave, which is line
clock.
Optional.
Disabled by default.
Optional.
FDL is disabled by default.
Optional.
16-bit CRC by default.
Optional.
The default is esf.
Optional.
Enabled by default.
This command is applicable when
the framing format is ESF.
Optional.
By default:
•
For LOS alarm, the threshold of
pulse-detection is 176 and the
threshold of pulse-recovery is
22. If the number of the pulses
detected during the total length
of 176 pulse detection intervals
is smaller than 22, the
pulse-recovery threshold, a
LOS alarm occurs.
•
Both AIS alarm threshold and
LFA alarm threshold are level- 1 .
Optional.
The default is 0x7E.
Optional.
The default is 0x7E.
