7 Configuration Command Reference
7.1.5 STREAM_XCON – Cross Connect Configuration
Synopsis
The STREAM_XCON command controls the cross connect switch on the signaling boards, enabling the cross-
connection of timeslots between two Line Interface Unit (LIU) on each signaling board. The LIUs on a board
are referenced by a fixed logical stream number.
Note: The <mode> option 1 and <pattern> parameter is not supported on DSI SS7MD Boards.
Syntax
STREAM_XCON <bpos> <stream_a> <stream_b> <mode> <ts_mask> <pattern>
Example
STREAM_XCON 3 2 3 3 0xfffefffe 0
Parameters
The STREAM_XCON command includes the following parameters:
• <bpos>
The board position of the cross connect switch to be controlled. There must be a valid board at this
position (previously defined by an SS7_BOARD command).
• <stream_a>
A reference to the 2 Mb/s stream for the output of the connection. There must be a valid LIU at this
position (previously defined by a LIU_CONFIG command). Valid values are:
• <stream_b>
A reference to the 2 Mb/s stream for the input of a simplex connection (mode 2) or one half of a duplex
cross connection (mode 3). In other modes, this field should be set to 0. There must be a valid LIU at
this position (previously defined by a LIU_CONFIG command). For valid values, see the table in the
<stream_a> parameter description above.
• <mode>
Indicates the requested cross connect switch function according to the following table.
• <ts_mask>
A 32-bit mask specifying the timeslots to apply the cross connect to. Each bit corresponds to a timeslot
in the input/output stream. Bit 0 (the least significant bit) corresponds to timeslot number 0. To apply
this command to a timeslot, the corresponding bit must be set to one.
