5.3 Terminating resistors
ISDN S
0
bus installations require that the ISDN S
0
bus is terminated at its
beginning and end by 100 Ohm terminating resistors. The outputs A1 to A4
of the
ISDN-TE-Hub home 1/4
are to consider as independent ISDN busses.
The resistors at the beginning of the bus of these outputs are integrated to
the
ISDN-TE-Hub home 1/4
. The terminating resistors at the bus end have
to be mounted into the ISDN wall outlets.
When using the ISDN cable included, it is not necessary to terminate the
input of the
ISDN-TE-Hub home 1/4.
Activate the internal terminating resis-
tors when installing the
ISDN-TE-Hub home 1/4
via installation cables by
using the terminal blocks. If the ISDN S
0
bus continues, deactivate the inter-
nal terminating resistors and terminate the bus at its end.
