source_st, source_ts

When mode is set to 11, these parameters give the source_st and source_ts for connection to the specified local timeslots. For other modes the source_st and source_ts specify the cross connect switch stream and timeslot, respectively.

6.3.8MVD_MSG_SC_DRIVE_LIU – LIU Switch Initialization

Description

This message is sent to connect selected CPU local bus timeslots from an T1/E1/J1 LIU or CPU stream to a block of cross connect switch channels. Upon receiving this message, switch channels are prepared to make a cross connect switch connection to outgoing CPU local bus timeslots upon receiving subsequent MVD_MSG_SC_LISTEN messages.

The confirmation message (if requested) indicates success with a status value of 0.

Parameters

liu_id

The identifier of the T1/E1/J1 Line Interface Unit (LIU) in the range 0 to one less than the number of LIUs. This parameter can be set to a value of a CPU local bus streams in the range of 0x90 upwards, where the number of CPU local bus streams equals one less than the number of LIUs. The timeslot value 0 to 31 in the ts_mask parameter correspond to the signalling processors signaling links.

sc_channel

The logical value of the first switch channel to be used. This should be in the range of 0 to the total number of channels available on the board.

ts_mask

A 32-bit timeslot mask where each bit position represents a local stream timeslot to be connected to the cross connect switch. The least significant bit (bit 0) represents timeslot 0. The arrangement of CPU local bus stream timeslot connections to cross connect switch channels is controlled by the mode parameter.
