Frequently Asked Questions
233
After restarting the OpenCom 100, nothing is indicated on the displays of any
connected terminals.
It takes a short while for the OpenCom 100 to start up.
After the restart, check whether the activity LED flashes at a rate of 10s / 1s. This flash
cycle indicates that the OpenCom 100 has started up correctly and is ready for oper-
ation.
If the OpenCom 100 has not restarted properly, reset the OpenCom 100 to its original
factory setting (refer to the chapter entitled Resetting the System Data starting on
page 90).
Telephony
It is not possible to make external calls.
Check the connection between the NTBA and the OpenCom 100.
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.
The OpenCom 100 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).
One of the telephones is not functioning at all.
Make sure the telephone has been properly connected.
Check also whether the appropriate port has been configured correctly in the Config-
urator ( Telephony: Ports menu).
