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.

Nevertheless, with ISDN a bus has to be formed to connect several users to one Basic Rate
Interface (BRI), but a bus cannot be formed with a star topology. Alternatively a complete
BRI must be dedicated to one user (point to point configuration), which is in many cases not
feasible or too expensive.

By using the active star BRI-Hub it is now possible to use the struct ured star-cabling concept
for ISDN. In addition the distance between the NT and the TEs may be extended because of
the use of point-to-point links between the BRI-Hub and the TEs. It is also possible to use the
"extended passive bus configuration" (distance up to 1000m) if all connections to the TEs are
in the same range of distance (+/- 50m).

The Phantom Feed unit can be used with the BRI-Hub to provide power to all 4 or 8 ports on
the BRI-Hub.

Description of functions

The BRI-Hub converts the ISDN BRI bus structure to a set of point-to-point connections,
which are connected within the BRI-Hub to form a 'logical bus'. At this, the BRI-Hub makes
it possible to hook up ISDN terminals via a maximum of 8 lines with the maximum length of
150 m each. Up to 1000 m is possible in a special configuration. Every port forms a separate
electrical segment. Through this wiring faults don't affect other segments.

BRI-Hub

If a BRI needs to be made available in several rooms, it used to be necessary to install a bus
from the server room through all rooms. (See picture ‘old’). Now star wiring can be used with
BRI-Hub, which comes to use also for telephone and local area networks (see picture 'with
BRI-Hub').

Options

BRI-Hub

This option derives its power from the power supply provided.

BRI-Hub S

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.
