Connection and Start of Operation of the Auerswald Box
Connect the Auerswald Box to the other devices as shown in the picture.
Configure an internal telephone number (e.g. 34) in the PBX for the analog port of the Auerswald Box
labeled with „PBX/Tk-Anlage“ – if this has not been done yet. You need this telephone number to call
the Auerswald Box for configuration settings or to make calls.
Configure an internal telephone number (e.g. 33) in the PBX for the analog port of the Auerswald Box
labeled with „ATA“ – if this has not been done yet. You need this telephone number to call the Auerswald
Box to make calls.
On both extensions do not configure any external telephone number (external call distribution).
For the connection of two PBX systems no settings are necessary in the Auerswald Box. If the Auerswald
Box does not contain the default factory settings concerning call acception (immediate) and destination
number (empty), you can reset it as described in the chapter “Reset to Default Factory Settings” on
