110 Data Path Routing (DPR) HighWire MTP-2 - 1.2, September 4, 2002
DPR_MODE. Changes the mode of operation for the Time Slot Interchanger
(TSI).
The putmsg control buffer is a structure of type dpr_mode_t with the mode_tsi
element a IOCTLTSIMODE structure that specifies the mode. The getmsg
control buffer returned is also a dpr_mode_t structure with the error code in
the mode_df.df_err element, which is zero on success. The elements in the
IOCTLTSIMODE structure are:
DPR_HOST_DATA. Tells the TSI to transmit the supplied data repeatedly.
The putmsg control buffer is a structure of type dpr_mode_t with the mode_tsi
element a IOCTLTSIMODE structure that specifies the host data. The getmsg
control buffer returned is also a dpr_mode_t structure with the error code in
the mode_df.df_err element, which is zero on success. The elements in the
IOCTLTSIMODE are:
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 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 with a valid range of
0 to 31.
UINT32 uiTxStream The Transmit Stream/TSI Highway Number with a valid range
of 0 to 31.
UINT32 uiRxTimeslot The Receive Time Slot Number with a valid range of 0 to 127.
UINT32 uiTxTimeslot The Transmit Time Slot Number with a valid range of 0 to 127.
UINT32 uiArg The use of this element varies by command. It is unused by the
DPR_MODE command.
INT32 index The Connection index into the Connection MAP
Matrix for this operation, if needed. (See
DPR_MODE)
UINT32 uiTSIMode Must contain the value TTSI_HOST.
UINT32 uiRxStream Ignored
