Description:
This message is sent to the board in order to generate a fixed pattern on a
specific timeslot of an E1 / T1 Line Interface Unit. It is typically issued at
initialisation and whenever a call terminates to generate an IDLE pattern
towards the network.
Parameter Description:
liu_id
The identifier of the E1/T1 Line Interface Unit in the range 0 to one less than
the number of LIUs fitted.
timeslot
The timeslot number on the E1/T1 line interface unit on which the fixed data will
be transmitted. The valid range for timeslot is 1 to 31 for an E1 interface and 1
to 24 for a T1 interface.
