Connecting Devices
Besides the Eumex 504PC SE, you can operate additional ISDN terminals (e.g. ISDN
telephones) on the NTBA. To simplify the connection of additional devices, you will
find an external S0 port on the lower side of the Eumex 504PC SE. This is the looped-
through S0 bus from the NTBA.
You can use the external S0 port to connect an additional ISDN terminal or a multiple
ISDN socket for more than one terminal. A fixed installation from the NTBA should
only be done by a qualified electrician.
Calls between terminals connected to the looped-through NTBA S0 bus and the ana-
logue terminals connected to the Eumex 504PC SE are routed via the telephone
exchange and are thus not internal calls.
