Automatic Connection - Telephone => Radio
An incoming phone call automatically occupies the line after N ringing signals. Two signal tones are
sent to the telephone (interval of 1 s). Subsequently, the phone call is forwarded to the radio. If the
function T11-55 is activated, the second signal tone is delayed until the channel is free. If the channel
is occupied for more than 45 seconds, the connection establishment is canceled. Please consult
also section T11-55. The conversation is terminated automatically by modulation monitoring or time
monitoring, or manually by a terminating call.

Direct Dialing with DTMF - Telephone => Radio
An incoming telephone call results in the automatic occupation of the line after N ringing signals and
a signal tone is sent to the telephone. In EEPROM register 361, 0-7 digits are preset. The missing
digits (coded with ‘F‘) are now added as DTMF-tones. The input of the call numbers is continued until
all 7 digits are (pre)set or entered. E.g. if a 5-tone sequence is to be sent, digits 6 and 7 may not be
programmed with ‘F‘. Else, additional (unused) DTMF digits have to be entered. After complete input
of the call number, the call is initiated automatically or by the end button of the telephone (usually the
‘#‘-button). If not all digits have been entered, the telephone participant receives an error message
(two short signal tones). If the function T11-55 is activated, the second signal tone is delayed until the
channel is free. If the channel is occupied for more than 45 seconds, the connection establishment
is canceled. Please consult also section T11-55. After transmission of the call a second signal tone
is sent to the telephone and the connection is established. In case of wrong input, the delete button
of the telephone (usually button ‘*‘) is able to delete the complete number and a new input can be
made.
Within 15s after the transmission of the call the last call can be sent again. It is also possible to call
several radio participants. Therefor, you can delete the last input with the delete button and start to
enter the next number.
5s after the input of the last DTMF digit the input mode is terminated automatically. If no call was
sent to a radio yet, the connection is terminated..
The conversation is terminated automatically by modulation monitoring or time monitoring, or manually
by a terminating call.
