uration program COMset).
If you only have this problem with some internal telephones, please

bus) and the PBX.

You can check the function of the NT by directly connecting an
ISDN telephone (If you have a Point-to-point ISDN line, the tele-
phone must be compatible to the Point-to-point connection). If there
is still no telephoning possible, disconnect the NT from the external
power supply (Pull the plug) and the exchange line for 5 seconds.
If the problem is solved, the NT had a malfunction. If the problem
remains, contact your network provider for help.

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
