Configuration of the SO bus termination

In TE mode, the termination depends on the cabling.

In NT mode the termination should be switched on, since the card then normally represents the end of the BRI bus.
Next to the block of jumpers for a connection, you will find a two-pole DIP switch which can be used to configure the BRI bus terminal.

If both pins of the switch are in the "ON" position, the 100ohm terminal is switched on, otherwise it is switched off.
| Both pins must have the same setting. |
