BRI-Hub

The screws must be put into the holes of the BRI-Hub. The screws slide approximately 25 mm into the case.

The screws can be screwed in tight.

Power Supply

BRI-Hub

The standard BRI-Hub is supplied with a wall mount power adapter. There is no power switch at the device. The BRI-Hub is active when the power adaptor is plugged into an outlet and the DC connector of the power adaptor is connected to the BRI-Hub.

BRI-Hub-S

Besides the operation with a power adaptor it is possible for a BRI-Hub-8S or BRI-Hub-4S to get its power through the power feeding of the NT or PABX via the NT port. Please note that the BRI-Hub needs approximately twice the power as an ISDN telephone. Therefore it is not possible to operate the BRI-Hub from the ‘restricted mode’ power feeding.

If the DC connector of the power adaptor is plugged into the BRI-Hub DC socket, the BRI- Hub will switch to the power adaptor automatically even if the power supply doesn't deliver any electrical power. Therefore it is necessary to unplug the DC connector from the BRI-Hub when the power feeding of the BRI is used.
