setting of SW30 controls the generation of the instance numbers.
Windows Systems: In a Windows system, leaving SW30 set to the 0 position (the factory default setting) on all Dialogic® telecom boards causes the system software to assign instance numbers geographically, based on the bus and slot numbers. Note that when using this method, there is no way to know what the instance numbers will be until the system is started and configured, and the instance number for any given board is likely to change when there is any change in the number or arrangement of boards in the system.
As an alternative, you may set SW30 on each board to a different position
CT Bus connector that complies with the ECTF H.100 specification, and as such can be connected to the CT Bus with a CT Bus cable. To connect the boards to the CT Bus, set the CT Bus jumpers according to instructions in this section.
If you do not require media sharing or switching across the CT Bus, you may use the
Note: If you are operating the board without a CT Bus connection, you must configure the board to H.100 bus mode. Otherwise, all attempts to download to the board will fail because the CT Bus clock is absent.

boards. Note that each board must be set to a different ID number.
In either case, you can read the ID numbers assigned to the boards in the Dialogic® Configuration Manager (DCM) after you start the system and invoke that tool.
Linux Systems: In a Linux system, you must explicitly specify the board ID numbers by setting SW30 on each board to a different position
The following instructions apply only to the boards at each end of the CT Bus cable. Boards that are in the middle of the CT Bus cable should not be terminated.
Note: If these boards are operating in SCbus mode, CT Bus (H.100) termination is not required.

Setting the Initial Hook State
The position of slide switch SW4 determines how the board responds to an incoming call when the chassis power is on but the board is not initialized. Set the SW4 slide switch as follows:
■SW4 = off (default): Callers hear ringing (on- hook).

Note: If the chassis power is off, callers hear ringing
To use the CT Bus:
■Install a jumper link on the JP2 jumper of a board to terminate the CT Bus at that board.
■Only terminate the first and last boards (the boards located at each end) on the CT Bus cable.
■Do not install a jumper link across the pins of JP2 on boards located between the end boards on the CT Bus cable (the jumper link must be disconnected on the JP2 jumper to disable termination).
The JP2 jumper terminates the following H.100 signals: CT_FRAME_(A&B) and CT_C8_(A&B).
