Reg. Function
367 1.- 3. digit: maximum receiving time for Simplex nnn * 1s
Modulation monitoring
The connection is disconnected after N seconds without speech modulation and the line
is free. The maximum duration of a call without speech modulation is adjustable from 1
to 99s or can be turned off with 0.
Ex factory it is set at 10s.
Reg. Function
365 5.- 6. digit: maximum length of call without modulation nn * 1s
Disconnection by ending call
The radio user can disconnect an existing telephone connection with two different kinds
of ending calls:
either by transmitting a tone sequence which has been configured as ending tone in one of
the telephone decoders T1-T10 or by transmitting a sequence of 7 DTMF-tones maximum
which have been programmed as ending call.
The pause between 2 DTMF-tones must not exceed 5 seconds.
Both ending call variants can be used together or alternatively.
Reg. Function
320-339 tone sequence decoder and corresponding configuration
359 1. digit: number of digits in the DTMF ending call (0-7)
359 2.-7. digit: code for ending call by DTMF
Signal tone delay
With all variants of connection setup (radio ==> telephone) a signal tone (acknowledging
tone) is transmitted to the radio subscriber. If the radio subscriber is not ready to receive
immediately after transmission of the signaling which releases dialing (tone sequence
resp.DTMF-tone) , maybe the signal tone cannot be received. In this case a signal tone
delay in steps of 100ms can be programmed.
Reg. Function
369 2. digit: signal tone delay to radio n * 100ms
The FT635UELE supports 3 operating modes for transmitter control
(Simplex (Vox)
,
Duplex
and
Simplex (carrier)
).
With
Simplex (Vox)
speech is decoded by telephone and radio. If one direction is activated
it will stay active as long as there is speech. Only afterwards the other direction can be
activated.
The delay times and levels for Vox are preset, but can be adjusted in the TIM.
With
Simplex (carrier)
the radio does not decode speech but the carrier input. The
following procedure is the same as with Simplex (Vox). With Simplex maximum times for
continuous transmitting and receiving can be set. If these times are exceeded the call will
be terminated.
With
Duplex
the transmitter stays busy till the end of the connection. In both Simplex
operation modes the transmitter is activated by speech control from the telephone. A certain
amount of time is needed to recognize speech and activate the transmitter. Because of
this,,a part of the first word is lost. To avoid this the UELE can delay speech from telephone
to radio. If a longer delay time is needed the speech can be compressed during the delay.
