This topic describes the following procedures for configuring the TX 4000 board:
The TX 4000 board connects to an H.100 bus. Boards on the H.100 bus are connected to one another with an H.100 bus cable. Enable bus termination on the board located on each end of the H.100 bus.
The following illustration shows the H.100 bus configuration:
DIP switch S2 on the TX 4000 board controls the H.100 bus termination. The DIP switch is located on the front of the board, below the H.100 bus connector. By default, all S2 switches are set to the OFF position. H.100 bus termination is disabled.
To enable H.100 bus termination, set all S2 switches to the ON position only for the boards that are on the ends of the H.100 bus.
Note: The switches in DIP switch S2 must be set to either all ON or all OFF.
The following illustration shows the H.100 termination DIP switch:
DIP switch S3 controls the SS7 Monitor mode. The DIP switch is located on the front of the board, to the right of the T1/E1 trunk connectors. By default, all S3 switches are set to the ON position. This setting disables SS7 Monitor mode. When SS7 Monitor mode is disabled, the TX board is an active participant in the network.
To enable SS7 Monitor mode, set the S3 switches to the OFF position. In this mode, the board becomes a passive listening device that monitors network traffic. For information on connecting the monitoring server (with an installed TX board) to the network and installing the SS7 Monitor software, refer to the Dialogic® NaturalAccess™ SS7 Monitor Developer's Reference Manual and to the Installing Dialogic® NaturalAccess™ SS7 Monitor Software instructions.
Note: The switches in DIP switch S3 must be set to either all ON or all OFF.
The following illustration shows the Monitor mode DIP switch:
DIP switch S1 controls the operation of the board. By default, only switch 2 (AUTOSTART) is set to the ON position; all other S1 switches are set to the OFF position. Switch 5 is reserved for future use. Do not modify the default settings for this switch.
Set switch 8 (SW MIN BOOT) to ON to boot the board to the original software image instead of using the current production software image. This allows for recovery from any condition that resulted in the corruption of the production software image. After setting this switch to ON, use txreset to boot the backup software image, and then use txflash to burn a clean copy of the production image. Once the production image is completely transferred to the board's flash memory, turn this switch to OFF, and issue txreset to boot the board using the newly loaded production software image.
