2.3 Adjusting Termination of S/T Interface (100 ohm)
You are able to set a port to NT or TE mode, please refer to figure 3 for
visualized information.
If a port works on NT mode, you should set jumper to CONNECT
(ON).
If a port works on TE mode, theoretically it should be set to OPEN
(OFF), but it might connect to some non-standard ISDN terminal
equipments that do not have terminal resistors, for such equipments,
you should set it to CONNECT(ON).
