Dialling tone detec-
tion
[
Yes / No
]
If
Yes
, the communication server waits for the dial tone from
the exchange before starting to dial.
Dialling tone time
[0...1200 seconds]
Maximum waiting time for the exchange dial tone if exchange
dial tone detection is activated. After that, the PBX switches
over to the next free trunk line. If dial tone detection is deacti-
vated, dialling begins after the set time, even without an
exchange dial tone.
International dial-
ling tone
[
No international dial-
ling tone
or 1…10]
If an international dialling tone is selected, the dialling process
is interrupted after one of 10 predefined digit sequences to
wait for the international dialling tone. The digit sequences are
defined under
International tone
at the routing elements
(CM_2.5.9).
Release signal
[
Yes / No
]
In most cases the public network sends the communication
server a release signal whenever the external user ends the call.
If the parameter is configured to
Yes
, the connection is subse-
quently cleared down by the communication server (see
"Clearing down Exchange-to-Exchange Connections",
page 243
").
Release signal type
[
Loop-break / Polarity
reversal / Congestion
tone
There are different types of release signals. The correct config-
uration depends on the carrier (see
to-Exchange Connections", page 243
Congestion tone
level
[
High / Low
]
The sound level of the congestion tone can vary greatly within
a country and depending on the line length. With this setting
the detection can be adapted to the existing level.
CLIP detection
[
Yes / No
]
"CLIP on analogue exchange accesses", page 108
Alerting signal type
[
No alerting signal
/
Ring pulse
/
Dual Tone
/
Line reversal & Dual
Tone
/
Not defined
]
There are different methods for transmitting CLIP data on ana-
logue exchange accesses. An alerting signal is needed to
detect CLIPs. The value of the parameter depends on the net-
work provider.
No alerting signal
:
Data transmission takes place between the first and second
ring signal. The first ring signal is used as an alerting signal.
Ring pulse
:
Data transmission takes place before the first ring signal. A ring
pulse is used as an alerting signal.
Dual Tone
:
Data transmission takes place before the first ring signal. Two
successive tones (Dual Tone) are used as the alerting signal.
Line Reversal & Dual Tone
:
Data transmission takes place before the first ring signal. A line
polarity reversal is used as the alerting signal, followed by two
successive tones (Dual Tone).
Not defined
: No data is detected.
CLIP data damping
[
Yes / No
]
The level of CLIP data varies from one network provider to the
next. An excessively high level can lead to detection problems.
Activating this parameter can attenuate the signal.
