326 Frequently Asked Questions
Question: After restarting the Forum 5004/5008/5012, nothing is indi-
cated on the displays of any connected terminals.
It takes a short while for the Forum 5004/5008/5012 to start up.
After the restart, check whether the activity LED (“Ready LED”) is illuminated
in green (call server) or yellow (gateway). This indicates that the
Forum 5004/5008/5012 has started up correctly and is ready for operation.
Further information can be found in the chapter
LED Display on a Hardware
Unit starting on page 43.
If the Forum 5004/5008/5012 has not restarted properly, reset the
Forum 5004/5008/5012 to its original factory setting (refer to the chapter
entitled
Resetting the System Data starting on page 148).

Question: It is not possible to make external calls.
Check the connection between the NTBA and the Forum 5004/5008/5012.
In the Configurator , check whether the external S
0
ports are configured
correctly ( Telephony: Ports: S
0
menu):
– Configuration of System- / Multi-terminal access OK?
– Port is connected to the NTBA?
– Faultless Cabling?
– Terminating resistors properly configured?
Check the status of the trunks. In the Configurator, open the System Info :
Telephony : Trunks page. For the Trunks used for the “External trunk” route
the Status indicator should display a small green hook symbol.
Question: The Forum 5004/5008/5012 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
0
port is set for an
NTBA in the communications system configuration; this additional port will be
used first to seize a trunk line.
Deactivate the corresponding S
0
port in the Configurator ( Telephony: Ports:
S
0
menu).
