Query or Transfer not possible
Pressing the FLASH key disconnects the Caller
ቢ The FLASH duration of the telephone is too long. Modify the set-
tings of the telephone (see manual of the telephone) or the settings
of the PBX with the function „learn FLASH time“ (see p. 63).
Pressing the FLASH key leaves you in the first Call
ቢ The FLASH duration of the telephone is too short. Modify the set-
tings of the telephone (see manual of the telephone) or the settings
of the PBX with the function „learn FLASH time“ (see p. 63).
ባ The FLASH-key of your telephone is configured as EARTH-key and
not as FLASH-key (see manual of the telephone).
A Query is not possible via T-Net-Function Key/Menu
ቢ Analog telephones equipped with T-Net-function keys or menus are
using a long FLASH (300 ms). Eventually your PBX is not confi-
gured for this FLASH timing. Most of the time an additional FLASH-
key is available at the telephone. Configure this key also for 300 ms
(see manual of the telephone) and let the PBX learn the FLASH tim-
ing (see p. 63).
You try a Query from an external Call to an internal Call and
hear the busy Signal
ቢ The called party is probably talking. Try again later.
ባ If you did not configure an (semi-restricted) exchange line access
with COMset for the called telephone, a Query call from an external
call would not be possible.
ISDN Telephone is ringing after putting the Receiver on-
hook and you are reconnected
ቢ Please check with the manual of your telephone, if „Transfers on a
PBX“ is activated. If not, try to correct this problem.
Pickup is not possible
Busy Tone during Pickup for external Call
ቢ If you did not configure an (semi-restricted) exchange line access
for business calls with COMset for the telephone, a Pickup of an
external call is not possible.
Busy Tone during Pickup on the internal S
0
Port
ቢ Probably both voice channels of the internal S
0
ports are busy.
Pick-up takes over ongoing Calls to another Telephone
ቢ The Takeover function and Pickup use the same functional proce-
dure. Switch off „conversation may be taken over“ via configuration
program for all telephones. The permission for a Takeover is only
useful for answering machines.
You cannot identify Door Bell ringing
Door Bell rings with the Rhythm „1 x long“
ቢ Check whether the internal Call Forwarding from the Door Terminal
for the corresponding telephone is switched on (configuration pro-
gram of the PBX).
ባ Check whether the CLIP function with the Telekom door signal was
switched on for the corresponding telephone (configuration pro-
gram of PBX).
PBX is not programmable
Busy Tone after entering the Password
ቢ Please check your password for correctness. If you forgot your set-
ting password that you need for the access with the configuration
program COMset, please contact the manufacturer. Functions that
can be done with the public password are also possible with the
secret password.
Programming with the PC is not possible
ቢ If you have this problem on the internal S
0
port, this port might be
restricted for PC programming. Try again on a different S
0
port, if
possible, or with the serial port.
ባ If you have this problem on the internal S
0
port, the ISDN PC-con-
troller might eventually not present an MSN (as a workaround, you
can configure with COMset a subscriber as „ISDN PC controller“ on
the S
0
port). Try again on a different S
0
port, if possible, or with the
serial port.
You can not program with one Telephone
ቢ Eventually the configuration of some functions (Call Forwarding,
remote switching, manual configuration switching) or all functions
are restricted for this telephone.
ባ If you configured a programming telephone, supervisor settings
(with secret password) would only be possible from that telephone.
ቤ If the telephone has been configured as a Direct Exchange Line Tel-
ephone (no 0 to reach the public exchange), you have to press the
little star key twice before programming.

ባ The USB port of your USB hub – if it exists – has been switched off.
One reason for this are electromagnetic interferences near the USB
hub. To eliminate this problem, there is an improved driver from
Microsoft. You will find more information about this matter on the
internet (English):
http://support.microsoft.com/support/kb/articles/Q236/9/34.ASP
The necessary driver to eliminate this error for Windows 98 second
edition (SE) can be ordered from Microsoft under the following tel-
ephone numbers:
Germany: 0180 5 67 22 55
Austria: 01 50222 22 55
Switzerland: 0848 80 22 55
You have to order a hotfix for the USB problem Q236934 and then
you will get the new driver usbhub.sys by Microsoft.
