Connecting analog users
You may connect all analog terminals to
the telephone system that you are also
permitted to operate on the public tel-
ecommunications network.
a/b terminals are:
- Telephones (a/b telephones) with tone
dialling (DTMF), an
r
key as the flash
key (flash time: 50 - 180 ms.), a
S
key
and a
R
key.
Only restricted use can be made of tel-
ephones that are set to pulse dialling.
- Group 3 fax machines
- Answering machines
- Modems (up to 28 800 bps)
Connect a/b terminals by means of two
wires to the La and Lb wires (speech
wires).
Connecting subscriber lines
- Mark the cables with the included mark-
ing system
- Strip 11 mm off the wires
- Push the individual wires into the termi-
nal until they move no further
without
pressing the terminal spring.
- To separate a connection, use a suitable
tool (screwdriver with narrow blade) to
press down the terminal spring and pull
out the wire.

The T Module 407 and 408 (User module)
T 407
Lb1, La1
not assigned
The T Module 407 features 7 interfaces for
a/b terminals. This modul supports the
CLIP function on a/b-terminal (Geman
CLIP)
The T-Modul 408 features 8 interfaces for
a/b-terminals. The T modul 408 doesn´t
support the CLIP function. With one T
module 407 the a/b-terminals on the T
module 408 have the CLIP function.
