A1.4 SCBUS_LISTEN Command
Syntax: SCBUS_LISTEN
Example: SCBUS_LISTEN 0 0 31 23
This command establishes a connection from the CT bus to an outgoing timeslot on the Line
Interface Unit (LIU).
Dynamic modification of voice paths can only be performed by issuing messages directly to the
board. The MVD_MSG_SC_LISTEN message is recommended for this purpose.
The logical identity of the board in the range from 0 to one less than the number of boards supported.
The identifier of the E1/T1 Line Interface Unit in the range 0 to one less than the number of LIUs
fitted. This parameter can also be set to the special value 0x83 to select the signalling processor
instead of an LIU. In this case timeslots 0 .. 3 correspond to signalling processor 0 .. 3 respectively.
The timeslot number on the E1/T1 line interface unit on which the data from the CT bus will be
transmitted. The valid range for timeslot is 1 to 31 for an E1 interface and 1 to 24 for a T1 interface.
The channel number on the CT bus to which the LIU will listen. This should be in the range from 0 up
to one less than the total number of channels on the CT bus.
