Please connect ISDN or S
0
system telephones by using the ISDN cables that came
along with those telephones.
With tiptel.com 822 XT and tiptel.comPact 84 Up4 per S
0
port there is only one con-
nector, i.e. you can only connect one ISDN system telephone. To connect more than
one ISDN telephone you will need a suitable ISDN switch or you will have to install an
S
0
bus.
With tiptel.com 822 XT Rack and tiptel.comPact 84 Up4 Rack per port there are two
connectors, so you may connect two ISDN telephones directly.
Notes:
You may only operate one S
0
system telephone per S
0
port.
A manual on how to install suitable ISDN switches or how to install an
S
0
bus you will find in the Installation Manual, which can be found on
the CD that came along with your telephone system.
ISDN cables used may not exceed 10 m in length. If the cables are longer then 10 m
at the end of the cable - before the telephone - termination resistors must be in-
stalled. With two telephones connected per port both telephones must be equipped
with termination resistors and the termination resistors which are factory default in the
telephone system must be removed.
Note:
A manual on how to install termination resistors you will find in the In-
stallation Manual, which can be found on the CD that came along with
your telephone system.
