System Telephones on the Comfort Pro S/T-Comfort 930 DSL
Using the U
pn
adapter you can connect an additional
T-Comfort 730 Systemtelefon or T-Comfort 830 Systemtelefo-
nas a second telephone. A second telephone connected via a
U
pn
adapter is completely independent of the first one. Connec-
tion via adapter is not a parallel connection.
When connecting a second telephone, you require a UP cable.
Use this cable to connect the additional T-Comfort Systemtele-
fon to the U
pn
adapter (1) on the first telephone.
The 2-wire UP cable must not exceed 30 m in length. Depend-
ing on the length of the cable and the type of T-Comfort Sys-
temtelefon connected as a second telephone, there may be
insufficient feed power. This could result in a decrease of the
ringer volume and the open listening/hands-free volume of the
second telephone. The feed power can be increased by con-
necting an external AC adapter (2).
Note:
U
pn
adapters on the communications system can only be
operated on telephones directly connected to the system. A
U
pn
adapter is not permitted on a second telephone.
The audio adapter is an adapter accessory with various sockets
for connecting external audio and signalling equipment.
You can use audio adapters on the T-Comfort 730 Systemtele-
fon and on the T-Comfort 830 Systemtelefon to connect audio
equipment and various accessories. The following interfaces
are available for external analogue equipment:
■
one 4-pole socket (1):
for connecting an ear cap, a second handset, a headset, an
external active loudspeaker, headphones or an external
microphone
■
one stereo socket (2):
for connecting recording equipment
■
one dummy socket (3):
