If the dealer uses an ETS-2106 I Rev. 2, ETS-4308 I, ETS-2204 I or an ETS-2104 I (or a
newer ISDN system), data is transferred between the systems much more quickly, since the
transfer is digital via the B channel. A normal configuration with a relatively old system
takes between about 10 and 30 minutes, whereas the digital configuration takes less than
one minute.
We offer you with your PBX an automatic update for your firmware. Apart from the telephone
charges that you incur, this update is free. As a result, the firmware is always up-to-date. We
do our best to integrate changes as quickly as possible into the current firmware. If you
should have functional problems with your PBX, you should first carry out a firmware update.
If this doesn't cure the problems, you should then consult your dealer.
When you use the following programming function to initiate the automatic firmware update,
your PBX makes an external connection to a server and downloads the current software. If
possible, you should only start this procedure during a quiet period (i.e. not in the most hectic
phase of a normal business day), since the PBX has to end all the other calls before carrying
out downloading of the software. Assuming that the PBX can make a connection to the
server, the entire process takes about five to six minutes.

To be able to carry out this procedure, the programming switch in the system (on
the PCB) must be in the “erlaubt” (allowed) setting.
The telephone rings for 60 seconds. If you do not lift the handset, then the PBX still carries
out the procedure but you cannot check whether everything functioned correctly (by hear-
ing the acknowledgement tone).
If you hear an engaged tone instead of the ringing tone or the acknowledgement tone after
punching in
971
, the connection is engaged. Replace the handset and try again later.
If you hear an engaged tone instead of the acknowledgement tone after the system calls
back, this indicates that the update did not function. In this case, you must repeat the entire
procedure.
If an external subscriber calls you during this procedure, you should complete the call
as soon as possible. If you don't do this, the PBX will probably interrupt the call automati-
cally.
If the procedure takes less than 60 seconds and you still hear an acknowledgement tone,
you already have the latest firmware version.
