Programming the System for SCbus Interface Board Operation
Once you have installed the SCbus interface board in the equipment cabinet and made the necessary cable
connections, you must perform several programming changes to make the board fully operational.
Installing the Board
1. Start the VMMI programming application.
2.
Go to the Board Configuration/Slot Assignment location.
3.
From the open Slot Assignment dialog window,
(a) click the slot where you installed the board,
(b) click open the board type dialog,
(c) click on the FX-SCB SC Bus board type,
(d) click the Apply button.
4.
Go to the Board Configuration/Board Programming/PCTB Boards location.
5. From the open PCTB Boards dialog window, configure the master clock setting as needed. Refer to the next
section.
6.
Go to the Board Configuration/Board Programming/SC Bus Ports location.
7. From the open SC Bus Ports dialog window, configure each SC port for Port Type and OAI Link. Refer to
the next section.
8. Test the installation to determine that the board is synchronized with Impact FXS’ CPU board.
Once installed, the system creates 32 additional station ports that correspond with the 32 telecom ports on the
SCbus interface board. (Future software and hardware revisions will enable installers to program these telecom
ports to be either station or line boards. At present, these ports can only be programmed for station boards or
disabled.)
