Frequently Asked Questions

Question: The mains plug is connected, the mains socket is

supplying output, but the Forum 500 still does not function.

DANGER! High voltage inside the device. To make the sys-

tem dead, remove the power plug from the socket!

Take the housing cover off. Is the “Power Fine” LED at the top left

lit up? If not, contact your service centre or an authorised dealer.

The AC adapter plug of the Forum 500 may be defective.

Question: After restarting the Forum 500, nothing is indicated on

the displays of any connected terminals.

It takes a short while for the Forum 500 to start up. After the

restart, check whether the activity LED flashes at a rate of 10s /

1s. This flash cycle indicates that the Forum 500 has started up

correctly and is ready for operation. If the Forum 500 has not

restarted properly, reset the Forum 500 to its original factory set-

ting (refer to the chapter entitled Resetting the System Data

starting on page 59).

Telephony

Question: It is not possible to make external calls.

Check the connection between the NTBA and the Forum 500.

In the Configurator, check whether the external S

ports are

configured correctly (PBX Configuration: S0 menu).

Question: The Forum 500 is connected to an NTBA with a multi-

terminal configuration. Why is it not possible to establish external

connections?

With the original factory setting, an additional external S

port is

set for an NTBA in system configuration; this additional port will

be used first to seize a trunk line.

Deactivate the second S

port in the Configurator (PBX

Configuration: S0 menu).

Question: One of the telephones is not functioning at all.
