Question: One of the features
(e.g. call diversion) on one of the
telephones cannot be used even
though the feature has been con-
figured in the Configurator of the
OpenCom 100.
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 fea-
tures cannot be used until the sys-
tem PIN is changed.
Question: Nothing is indicated on
the display of one of the connected
ISDN telephones.
You have connected the ISDN tele-
phone to an external S
socket). These ports are intended for
connection to the NTBA only. Con-
nect the telephone to an internal S
port (pressure terminal).
Question: Calls can be made but
not received with one of the ISDN
telephones.
The internal call number that has
been configured for this ISDN tele-
phone in the Configurator (PBX
Configuration: Ports: S0 menu)

ther information, refer to the User

Question: It is not possible to con-
figure Call Distribution: Outgoing
for multi-terminal access.
You have configured multi-terminal
access and system access in parallel.
All outgoing calls are therefore es-
tablished via system access, and out-
going call distribution can be config-
ured for system access only
(Configurator, Call Distribution:
Outgoing menu).
A specific MSN can be seized for indi-
vidual calls by means of a code
number procedure. For further infor-
mation, refer to the "OpenCom 100,
Operation on Standard Termi-
nals"user guide.
Question: Which reason may have
problems with receiving faxes
resp. sending 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 distri-
bution and the introduced signalling
jitter is overheard by the human ear.
Nevertheless, data and fax transmis-
sions may be disturbed by the jitter.
Please check, which ISDN lines will
deliver the L1 clock. Details can be
found under L1 Clock starting on
page 77.
