Page 4: Introduction
BRI-Hub Introduction Within the data communications and LAN industry it is well known that a structured cabling concept using a star topology has significant advantages, such easier maintenance, unproblematic changes in the configuration and faster fault finding. Last but not least, a structured cabling concept may be used for all kinds of LAN-, WAN and telecommunications technologies. -
Page 5: Options
This option derives power from the S-Bus and uses an internal DC-DC converter to adapt the voltage to power itself – no external power supply is required. This option is available as a special request from Black Box. Both of the above options can be used in conjunction with the Phantom Feed, a device used to provide power on each of the hub’s S interfaces. -

Page 7: Power Supply
BRI-Hub Environmental and Safety Notes The device conforms to all european and international standards for safety, environment, EMC and the ISDN basic rate interface. Power Supply The power adaptor is according to safety class II (VDE 0551) and my only be used indoor. -
Page 8: Installation
For the assembly into a rack an optional 19” front panel is needed. This may hold one or two BRI-Hub devices. This 19”rackmount panel is available as a special from Black Box. Please call technical support for further information. The front panel is fixed to the BRI-Hub devices by two engine screws. -
Page 9: Power Supply
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. -
Page 10: Connecting The Hub
BRI-Hub Connecting the Hub 6V DC The DC connector of the power adapter is inserted into the jack on the left side of the rear panel (Jack "6V DC"). Do not use other power adaptors than the original one. In any case notice the polarity of the connector. -
Page 11: Power Failure Operation
BRI-Hub The TE-ports termination resistors are permanently active and cannot be switched off. Please install terminating resistors to the end of the connecting cables. In the above example the Term-switch must be in the off position, i.e. termination resistors are off. This is because the BRI-Hub is not connected to the end of the bus. Power Failure Operation If the BRI-Hub loses power, the terminal devices directly connected to the NT ports will still operate. - Page 12 BRI-Hub Configuration for power fail communication with the BRI-Hub If cable connections between the BRI-Hub and the terminal equipment (TE) are longer than the proposed 150m, operation may be possible under specific conditions: 1. The NT must be switched to "extended passive bus". "Point-to-point" or "adaptive timing”.

Page 13: Termination Resistors
BRI-Hub Termination Resistors The signal pairs must be terminated with 100 resistors at both ends of the bus. These must be installed as shown below. If not placed correctly, they may short the power feeding voltage. Pin description Direction each TECHNICAL: 0118 931 2233... -
Page 14: Operation
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). -
