Connecting to a Basic Rate ISDN line
Where the recorder is used as an ISDN recorder and placed in between
the ISDN line (NT) and and the ISDN PBX (TE), it is recording all incoming
and outgoing traffic. The line coming from the ISDN network provider is
plugged into the PBX connector (4 of page 4), and the ISDN PBX or
telephone is connected to the Phone connector (3 of page 4).
Normally an ISDN line uses RJ-45 connectors.
Also note that in all operating modes the line is terminated with 100
Ohm resistors, except for the TE input in ISDN (S0) mode. The TE input is
designed for a short, (less than 50 meters) point to point connection,
and therefore is not terminated. If you want to use a longer cable, or
point to multipoint connection, you may want to add your own
terminating resistors, between pins 4 and 5, and 3 and 6 of the ISDN
connector. In Up0 mode all connections are terminated.
The figure below is an example of a possible setup of the Call Recorder
Single Digital on a Basic Rate ISDN line.
Note that although a PABX is connected, it is still connected to the
“phone” ISDN output connector, while the “PBX” input connector is
connected to the ISDN NT1 adapter (with a short cable).
