Global TTL Parameter
• For the function Function Code: Call Number (level triggered) (see
PAGE 77) you can program a delay for the disconnection within the range
of 0...127 seconds. If you select 0, the connection is dropped immediately.
This setting is helpful, e.g. if you realized an automatic dialling via VOX
control. If nobody is speaking, the connection would be dropped imme-
diately by default. If you have set a delay, short breaks in the speech/Au-
dio signal do not result in an immediate disconnection.
