Parameter Description:
liu_id
The identifier of the T1/E1 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 signaling processor instead of an LIU. In this case,
timeslots 0 ... 3 correspond to signaling processor 0 ... 3 respectively.
Note: For the SPCI2S, valid values for the LIU identifiers are 2 and 3.
timeslot
The timeslot number on the T1/E1 line interface unit on which the data from
the CT bus is transmitted. The valid range for timeslot is 1 to 31 for an E1
interface and 1 to 24 for a T1 interface.
sc_channel
The channel number on the CT bus to which the LIU listens. This must be in
the range 0 to one less than the total number of channels on the CT bus.
Status Response
The confirmation message (if requested) indicates success by status of zero.
On error, the following status values can be found in the confirmation
message.
Value Mnemonic Description
0xd2 MVIP_INVALID_STREAM Invalid stream specified in listen request.
0xd3 MVIP_INVALID_TIMESLOT Invalid timeslot specified in listen request.
0xff None Invalid message length.
