BRI-Hub

Operation

No service is needed during operation.

Cable shorts at one TE port only affect the power feeding voltage of all ports if they are internally connected. To reduce this effect self-healing fuses are connected to each port.

The current version of the BRI-Hub cannot clear problems with cable reversals of the TE pair (Pins 3 and 6 of the RJ-45). If one of the connected TEs has such a pair reversal, no operation is possible since the pulses sent by different TEs have different polarity.

Displays and Controls
