Telephones with the correct authorization can activate Call Forward-
ings. The possible problem is that the Call Forwardings are forgotten
later. With the following initialization functions, you will delete the set-
tings that affect the call distribution. Please keep in mind that you are
eventually deleting settings that need to be reconfigured later.
If you like to have changes to the settings of your PBX to be made by
your dealer later, it will not be necessary that a service technician
comes to your home. The function remote programming enables a serv-
ice technician, with help of the corresponding devices, to read the data
out of the PBX or to reprogram during an external telephone connection.
He needs your permission of course. And if you give your permission by
dialling certain digits, the service technician will be able to do the remote
diagnosis or the remote programming only for a short time frame.
Remote Programming
³ The service technician explains to you by telephone what he will do
with the configuration data of the PBX.
· If you agree to the operations of the service technician, he will ask
you to go to one of your subscriber telephones of your PBX and to
dial the digits
99 or F99. You open the PBX and the con-
nected COMfort 2000 for remote programming or remote reading.
Follow the instructions of your service technician.
If the service technician only reads the data out of the COMfort 2000
first, a repetition of this procedure will be necessary to transfer the data
later.
An update of the firmware of the PBX could be necessary or useful if
there are functional problems or if new features are offered. Ask your
dealer whether an update would be the solution to your problems. Or
inform yourself on the latest news about the PBX software - on our
homepage in the Internet.
The update is started with a programming sequence. If the update is
executed via ISDN over the exchange line as described in the following,
the PBX will establish a connection with a server in order to let the
actual software be transferred. The settings of the PBX are not changed
1. Authorized personnel: These are persons that are trained for this purpose (e.g.
certified electricians). They must have the necessary knowledge about the
work in an area with potentially hazardous voltage. They must also have the
knowledge about the latest electrical safety standards and requirements.
