Installation
Port assignment, termination, cable length

Several IAE sockets can be series connected using a bus installation. For the fol-
lowing example, activate the
PBX Configuration
:
Ports
:
S0(#)
:
Line termination
option in the
Configurator
. In the last IAE socket, 100 ohms terminating resistors
between 1a and 1b as well as between 2a and 2b are required.
Connecting several IAE sockets
IAE = ISDN wall socket (German ISDN „Anschluss Einheit”)
If the S0 bus is coming from the OpenCom X320 leading to one or more IAE sockets, the
terminating resistors (“TR”) in the OpenCom X320 and in the most distant IAE socket
needs to be switched on.
