Configure Analog Connection
When performing the features sup-
ported by the Analog/ISDN Converter
(e.g. call forwarding) the # will be trans-
mitted to the central office independent of this
setting.
Length of the flash signal: Select the time
required by the network provider. For the use of
features provided by the network provider such as
Query or conferences often a longer flash time
(e.g. 170-300 ms; in Germany a flash time of
300 ms is necessary) is necessary. A flash time
which is configured too long may be recognized as
an on-hook by the central office.
Line impedance selection: Select the configura-
tion matching to your network provider. This guar-
antees the best voice quality on the lines.

Line Seizure

Wait for dial tone: Before the Analog/ISDN Con-
verter starts to dial a number a dial tone detection
may be performed to check the proper line sei-
zure.
Activate this setting if the dial tone generated by
the central office is delayed by a longer time. You
will prevent dialling errors by too early dialling
attempts of the Analog/ISDN Converter. The Ana-
log/ISDN Converter will dial as soon as it has
detected a dial tone or after the delay time has
elapsed.
Deactivate this setting if the dial tone of the cen-
tral office is not reliable and may not be detected
correctly by the Analog/ISDN Converter. The Ana-
log/ISDN Converter starts to dial after this delay
time has elapsed.
Waiting time (1 - 30 seconds): Enter the maxi-
mum time to wait for the dial tone from the central
office. The Analog/ISDN Converter will start to dial
after this delay time has elapsed under any cir-
cumstances.
Send automatic prefix: If the central office al-
ways needs a certain digit sequence not belonging
to the number, you can add this digit sequence in
front of the number automatically by the Analog/
ISDN Converter. Activate this setting and enter the
digit sequence – if necessary with a following ","
(comma) as pause character.
Detect prefix and wait: If the central office needs
a pause after a prefix code, you may add this
pause automatically in the Analog/ISDN Converter
after a certain digit sequence. Activate this setting
and enter the digit sequence (e.g. a provider ac-
cess code). As soon as the Analog/ISDN Convert-
er detects this digit sequence at the beginning of a
dialled number, the pause will be inserted before
dialling the following number.
Waiting time (1 - 6 seconds): Enter the time to
wait after the prefix code before the following digits
are dialled by the Analog/ISDN Converter.
Loop current detection
is supporting the loop current detection for detect-
ing the line seizure, activate this function. If no
loop current is detected, the line is considered to
be busy and – after checking the setting "Over-
flow" – the other analog line will be used.

Start of Call (outbound call)

Busy tone detection: After dialling a number the
Analog/ISDN Converter can perform a busy tone
detection to check the busy status of the called
subscriber.
If you activate this setting (recommended), the
busy tone of the central office will be detected by
the Analog/ISDN Converter. This is necessary to
activate the function CCBS (callback on busy) with
internal telephones of a PBX.

Line Reversal : If the network provider is sup-
porting the line reversal at the start of the call, ac-
tivate this function. The line reversal will be used
as a signal for the call start then.
