126 Data Path Routing (DPR) HighWire MTP-2 - 1.2, September 4, 2002
Arg points to a IOCTLTSIMODE structure with the following elements:
DPR_HOST_DATA. This command causes the TSI to transmit the supplied data
repeatedly. Arg points to a IOCTLTSIMODE structure as described in
DPR_MODE except for:
DPR_IDLE_CODE. This command causes the TSI to operate in Idle Code
substitution mode. Arg points to a IOCTLTSIMODE structure as described in
DPR_MODE except for:
INT32 index The Connection index into the Connection MAP Matrix for this
operation, if needed. The MAP Element associated with this
index will have its mode value updated to reflect the current
mode of operation. The index is a signed 32-bit integer and has
a valid range of −1 to MAX_CONNECTIONS −1. A value of −1
performs the operation but does not update the mode value in
the MAP structure. The index for a particular connection may be
determined with the DPR_IS_TXCONNECTED and
DPR_IS_RXCONNECTED commands.
UINT32 uiTSIMode The particular sub-mode operation being carried out by the TSI.
Valid sub-mode values for the DPR_MODE operation are
TTSI_LOWLAT, TTSI_FRAMEI and TTSI_TRISTATE.
UINT32 uiRxStream The Receive Stream/TSI Highway Number. It is an unsigned
32-bit integer with a valid value range of 0 to 31.
UINT32 uiTxStream The Transmit Stream/TSI Highway Number. It is an unsigned
32-bit integer with a valid value range of 0 to 31.
UINT32 uiRxTimeslot The Receive Time Slot Number. It is an unsigned 32-bit integer
with a valid value range of 0 to 127.
UINT32 uiTxTimeslot The Transmit Time Slot Number. It is an unsigned 32-bit integer
with a valid value range of 0 to 127.
UINT32 uiArg The use of this element varies by command. It is unused by the
DPR_MODE command.
uiTSIMode Must contain the value TTSI_HOST.
usRxTimeslot The Host Data to be sent out over the connection.
uiRxStream Ignored.
uiTSIMode Must be one of TTSI_IDLE1, TTSI_IDLE2, or TSSI_IDLE3.
usRxTimeslot Ignored.
uiRxStream Ignored.
