Frequently Asked Questions Telephony
After restarting the OpenCom 510, nothing is indicated on the displays of any connected terminals.
It takes a short while for the OpenCom 510 to start up.
After the restart, check whether the activity LED flickers in a regularly interval. This indicates that the OpenCom 510 has started up correctly and is ready for operation. Further information can be found in the chapter
Modules starting on page 59.
If the OpenCom 510 has not restarted properly, reset the OpenCom 510 to its
original factory setting (refer to the chapter entitled Resetting the System Data starting on page 92).

Telephony
It is not possible to make external calls.
Check the connection between the NTBA and the OpenCom 510.
In the Configurator , check whether the external S
0
ports are configured correctly
( PBX Configuration: S
0
menu):
– Configuration of System- / Multi-terminal access OK?
– Port is connected to the NTBA?
– Faultless Cabling?
– Terminating resistors properly configured?
The OpenCom 510 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 system configuration; this additional port will be used first to seize a trunk line.
Deactivate the corresponding S
0
port in the Configurator ( PBX Configuration: 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
Configurator ( PBX Configuration: Ports menu).

Frequently Asked Questions Telephony
It is not possible to make external calls with one of the telephones.
Check whether a user is configured for the telephone. Otherwise the settings of the Guests user group are valid for the telephone. To standard, this user group has no external call authorisation.
Make sure the user configured for this telephone belongs to a user group with external line access ( Configurator , User Manager: User groups menu).
Check also whether the internal call number of this telephone has been configured for incoming call distribution ( Configurator , PBX Configuration: Call Distribution menu).
One of the features (e.g. call diversion) on one of the telephones cannot be used even though the feature has been configured in the Configurator of the
OpenCom 510.
Make sure the user configured for this telephone belongs to a user group that has access to this feature ( Configurator , User Manager: User and User groups menus). Some features cannot be used until the system PIN is changed.
Nothing is indicated on the display of one of the connected ISDN telephones.
You have connected the ISDN telephone to an external S
0
port (RJ-45 socket).
These ports are intended for connection to the NTBA only. Connect the telephone to an internal S
0 port (pressure terminal).
Calls can be made but not received with one of the ISDN telephones.
The internal call number that has been configured for this ISDN telephone in the
Configurator ( PBX Configuration: Ports: S0 menu) must also be configured as an MSN on the ISDN telephone itself. For further information, refer to the User
Guide of your ISDN telephone.
An ISDN telephone always rings, if another telephone on the S
0
bus is being called.
This case also requires configuring the MSN on the ISDN telephone (see above answer).
It is not possible to configure Call Distribution: Outgoing for multi-terminal access.
You have configured multi-terminal access and system access in parallel. All outgoing calls are therefore established via system access, and outgoing call distribution can be configured for system access only ( Configurator , Call Distribution menu).

Frequently Asked Questions DECT
A specific MSN can be seized for individual calls by means of a code number procedure. For further information, refer to the “OpenCom 100, Operation on
Standard Terminals”user guide.
What are some of the causes for problems when sending and/or receiving faxes?
In frequent cases, the reason may be found in a problem with the ISDN-L1 reference clock distribution. The L1 clock is delivered from the network provider. An unclean L1 clock distribution and the introduced signalling jitter is overheard by the human ear. Nevertheless, data and fax transmissions may be disturbed by the jitter. Please check, which ISDN lines will deliver the L1 clock. One of the installed
ISDN interface boards (MX+S01-8 or MT+S2M1-1) should show a steady green
light with LED 3. Details can be found under L1 Clock starting on page 151.
The fax data transfer possibly is routed via a compressing VoIP connection. Please verify, if the a/b port is configured with the “Fax” setting. For the VoIP connection, select a VoIP profile which includes the non-compressing G.711 codec.

DECT
The LED of the RFP 22/24 base station is flashing, but none of the DECT devices is functioning.
Make sure the terminal setting for the corresponding U pn
port is set to RFP 22/24
( Configurator , PBX Configuration: Ports: U pn
menu).
If multiple RFP 22/24 base stations are installed, the blinking LED indicates that synchronisation is not finished.
The LED of the RFP 22/24 is continuously lit up, but one of the cordless DECT devices is indicating “No connection”.
You have not registered this DECT device. Configure a port in the Configurator and start the enrolment procedure ( PBX Configuration: Devices: DECT Phones menu).
Is it possible to increase the time for the enrolment procedure?
You must manually enter the IPEI of the DECT device in the Configurator . The enrolment time is then increased to one hour ( PBX Configuration: Devices: DECT
Phones menu).

Frequently Asked Questions LAN
Another manufacturer’s DECT device is not functioning.
Check whether the DECT device supports the DECT GAP standard. In the Configurator , also make sure GAP is set for this DECT device ( PBX Configuration:
Devices: DECT Phones menu).
The startup procedure of the RFP 22/24 take a long time? What is the reason?
This behaviour may indicate a problem with the reference clock. Refer also to
What are some of the causes for problems when sending and/or receiving faxes?
starting on page 204.
19.4
LAN
Why is it not possible to establish a network connection with the
OpenCom 510?
Check whether the LEDs for the switch and the PC’s network card are indicating a connection.
Check the LEDs for the LAN functions of the OpenCom 510.
To check whether there is a network connection with your OpenCom 510, enter the “ping IP address” command in “Run” in the Windows Start menu (e.g. ping
192.168.99.254).
How can I determine the IP address of the OpenCom 510?
To find out what the IP address is, enter the code number *182 on one of the connected system telephones.
The code-number procedure *183 also displays the network mask.
The network connection is functioning, but nothing is displayed in the browser.
Enter the complete IP address of the OpenCom 510 along with the protocol identifier, for example http://192.168.99.254/.
Check whether the browser has been configured for connection through a proxy server. If so, deactivate the “Connect through proxy server” setting.
