Switchable S0 connection S0 0/2(internal or external S0 connection) ¢¢¢¢¢¢
External S0 connection S0 0/2
You may connect the external SO
Connection to a System Access (PTP) or
Standard Access (PTPM) line. Please refer
to External SO Connection (RJ45 Socket).
Use the enclosed ISDN Cable and connect
the four wires to the SO connection block
of the module.
- Push the wire all the way into the
connection block without pressing the
release catch.
- Connector: a1 -green
b1 -brown
a2 -yellow
b2 -white
- To disconnect a wire, press the release
catch with a small screwdriver while at
the same time pulling out the conductor.
- Guide the cable through the cable comb.
Termination Resistors for the external SO
Connection
System Access (PTP)
–Both switches
S1301/cd for the 100 Ohm terminators
must be closed ("as-delivered" setting).
Standard Access (PTMP)
- Both switches
S1301/cd for the 100 Ohm terminators
must be:
-
closed or set to 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 set to 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.
Plug the ISDN Plug into the ISDN
connection after completion of all
installation work.
Both switches S1301/cd are on the compo-
nent side of the module.
Do not insert the Western plug of the con-
necting cable into your ISDN connection
socket until all installation work has been
completed.
Internal S0 connection S0 0/2
You can connect up to 8 ISDN devices like
on a PTMP connection on the internal SO
Bus of the System.
ISDN Apparatus:
Digital AGFEO System Phones (max 2
digital phones per SO Bus)
-ISDN -Telephones
-ISDN -PC-Cards
-ISDN –Fax machines
Up to four ISDN devices without additional
power may be connected. For example: 4
ISDN Telephones or 2 Digital System
Phones plus 2 ISDN Telephones.
Connections of further ISDN devices will
need their own power source.
ISDN Apparatus must use the DSS1
protocol.
You will need the following material to
install an internal SO Bus.
Telephone wire CW1308 (minimum 2 pair)
or CAT5 Cable
RJ45 Sockets max. 12 per Bus
2 Termination Resistors, 100 Ohm 0.25 W
Maximum SO Bus length will be 130 m.
(Telephone System to last RJ45 Socket)
Termination Resistors for the Internal SO
Connection
The internal SO Bus must be terminated.
Install two 100 Ohm Resistors in the last
RJ45 Socket
(See Diagram). Both witches S1301/cdmust
be closed.
