Requirement An E1 or T1 is required to transmit both signaling and voice timeslots to the line interface of the Dialogic® Distributed Signaling Interface (DSI) SS7 board. The signaling is processed locally with the voice timeslots cabled to another piece of equipment via a second line interface. Configuration The LIU_SC_DRIVE is used to set up a switch path through the board between the receive path of the Line Interface Unit (LIU) and the CT bus, and the SCBUS_LISTEN command establishes a connection from the CT bus to the transmit path of an outgoing timeslot on the Line Interface Unit (LIU). An example configuration is shown below. The commands and other parameters are described in the programmer's manual for each board type. Config.txt based configuration: Syntax for LIU_SC_DRIVE: LIU_SC_DRIVE <board_id> <liu_id> <sc_channel> <ts_mask> [<mode>] These LIU_SC_DRIVE commands drive the receive path of the voice bearer timeslots from the LIUs to the CT bus: LIU_SC_DRIVE 0 0 512 0xfffefffe LIU_SC_DRIVE 0 1 542 0xfffefffe The above commands mean: on Board 0, LIU 0, drive the receive path of 'voice' timeslots up onto the CT bus from channel 512, and on Board 0, LIU 1, drive the receive path of 'voice' time slots up onto the CT bus from channel 542. In this example the mask used does not drive timeslot 0 and timeslot 16 to the CT bus. Timeslot 16 (assuming that signaling is being carried) can be connected to the signaling processor as normal using the MTP_LINK command. You should not attempt to drive timeslot 0 to the CT bus. To set the transmit path of the timeslots to listen to the CT bus requires a separate command for each timeslot on each LIU using the SCBUS_LISTEN command. Syntax for SCBUS_LISTEN: SCBUS_LISTEN <board_id> <liu_id> <timeslot> <sc_channel> The 60 commands would be: SCBUS_LISTEN 0 1 1 512 SCBUS_LISTEN 0 1 2 513 SCBUS_LISTEN 0 1 3 514 SCBUS_LISTEN 0 1 4 515 SCBUS_LISTEN 0 1 5 516 SCBUS_LISTEN 0 1 6 517 SCBUS_LISTEN 0 1 7 518 SCBUS_LISTEN 0 1 8 519 SCBUS_LISTEN 0 1 9 520 SCBUS_LISTEN 0 1 10 521 SCBUS_LISTEN 0 1 11 522 SCBUS_LISTEN 0 1 12 523 SCBUS_LISTEN 0 1 13 524 SCBUS_LISTEN 0 1 14 525 SCBUS_LISTEN 0 1 15 526 SCBUS_LISTEN 0 1 17 527 SCBUS_LISTEN 0 1 18 528 SCBUS_LISTEN 0 1 19 529 SCBUS_LISTEN 0 1 20 530 SCBUS_LISTEN 0 1 21 531 SCBUS_LISTEN 0 1 22 532 SCBUS_LISTEN 0 1 23 533 SCBUS_LISTEN 0 1 24 534 SCBUS_LISTEN 0 1 25 535 SCBUS_LISTEN 0 1 26 536 SCBUS_LISTEN 0 1 27 537 SCBUS_LISTEN 0 1 28 538 SCBUS_LISTEN 0 1 29 539 SCBUS_LISTEN 0 1 30 540 SCBUS_LISTEN 0 1 31 541 SCBUS_LISTEN 0 0 1 542 SCBUS_LISTEN 0 0 2 543 SCBUS_LISTEN 0 0 3 544 SCBUS_LISTEN 0 0 4 545 SCBUS_LISTEN 0 0 5 546 SCBUS_LISTEN 0 0 6 547 SCBUS_LISTEN 0 0 7 548 SCBUS_LISTEN 0 0 8 549 SCBUS_LISTEN 0 0 9 550 SCBUS_LISTEN 0 0 10 551 SCBUS_LISTEN 0 0 11 552 SCBUS_LISTEN 0 0 12 553 SCBUS_LISTEN 0 0 13 554 SCBUS_LISTEN 0 0 14 555 SCBUS_LISTEN 0 0 15 556 SCBUS_LISTEN 0 0 17 557 SCBUS_LISTEN 0 0 18 558 SCBUS_LISTEN 0 0 19 559 SCBUS_LISTEN 0 0 20 560 SCBUS_LISTEN 0 0 21 561 SCBUS_LISTEN 0 0 22 562 SCBUS_LISTEN 0 0 23 563 SCBUS_LISTEN 0 0 24 564 SCBUS_LISTEN 0 0 25 565 SCBUS_LISTEN 0 0 26 566 SCBUS_LISTEN 0 0 27 567 SCBUS_LISTEN 0 0 28 568 SCBUS_LISTEN 0 0 29 569 SCBUS_LISTEN 0 0 30 560 SCBUS_LISTEN 0 0 31 561 Message-based configuration: You can also use message-based scripts. When using config.txt, S7_Mgt generates MVD_MSG_SC_DRIVE_LIU from the LIU_SC_DRIVE and MVD_MSG_SC_LISTEN from the LIU_SC_LISTEN commands. Here is an example of message-based script: *MVD_MSG_SC_DRIVE_LIU for LIU 0 and LIU1 M-I0000-t7e18-i0000-fef-d10-r8000-p00000200fffefffe0001 M-I0000-t7e18-i0000-fef-d10-r8000-p0001021efffefffe0001 * MVD_MSG_SC_LISTEN on 6 timeslots.
