You may connect any analogue apparatus to the system which has been approved for
connection to the public switched telephone network.
a/b-Apparatus is:
- Telephone (2 wire Phone or POT) either LD or MF Dialling with Timed Break Recall (TBR)
(60 – 800 ms)
- LD Phones may only have limited feature access.
- Fax machines Group 3
- Telephone Answering Machines
- Modem 56k (V.90 to 56600 bps, may reduce to 33600 bps due to quality of lines V.34+)
Connect the analogue apparatus via 2 wires to the a and b wire (Speech Pair) of the system
port
Connection of wire
- Strip the cable by 11 mm.
- Push the single wire all the way into the connection block without pressing the release
catch.
- To disconnect a wire, press the release catch with a small screwdriver while at the same
time pulling out the conductor

System Access Connection
You can only connect a telephone system to a system access connection or also known as
point to point connection. Other ISDN devices cannot be connected. The system can be
connected directly to the NTTP via the enclosed ISDN Cable. You can also connect to a
socket which is then connected to the NTTP.
Termination Resistors for the external SO Connection SO-0
Both switches for the 100 Ohm Termination Resistors must be set to on for the System
Access Connection.
Standard Access Connection
A Point to Multi Point connection may be installed as a SO Bus type and up to 12 ISDN
Sockets can be connected to this. The telephone system and up to seven additional ISDN
devices may be connected to the SO Bus.
Termination Resistors for the external SO Connection SO-0
Both switches for the 100 Ohm Resistors must be set as follows:-
-
-
- - - closed or on if the connection is made directly onto the NTTP or on the last socket which
has no 100 Ohm Termination Resistors fitted.
- - - - - open or off if the last socket has the 100 Ohm Termination Resistors installed or if the
telephone system is not the last ISDN device on a PTMP line.
Connect the phone system directly with the ISDN connection cable to an ISDN socket of the
SO Bus or to the NTTP if the installation has no SO Bus option.
