3 SS7HD Board Product Specific Configuration and Operation

Note: All 32 signaling links from board 1, signaling processor 0, are driven up to CT Bus channels

0x0100 to 0x0120.

3.4.7 Interconnecting LIUs using STREAM_XCON

Interconnection of two Line Interface Units (LIUs) on the board is also supported

through the STREAM_XCON command which controls the cross connect switch on the

signaling board, enabling the cross connection of timeslots between any two LIUs

within the board. This command simplifies the cross connection enabling a group of

timeslots on one LIU to be directly mapped to the same numbered timeslots on a

second LIU on the same board using a single command. A typical usage of the

STREAM_XCON command is shown in Figure 2 which implements Drop and Insert

functionality.
