Backup Timer
The timing of the backup can be adjusted with the following timers:
• Timer 1 (Minimum alarm event duration) in milliseconds: Under this set-
ting you can select the minimum duration of a TTL alarm to trigger a
backup. This is to avoid that a backup is established because of very short
disturbances.
The timer can be configured within the range of 0 ... 12700 ms in steps of
100 ms.
• Timer 2 (Toggling alarm detection interval) in seconds: This timer ensures
that a backup is also triggered when the alarm signal is „toggling“. If the
alarm signal is detected for a second time within the selected interval, the
backup connection is established in any case.
The timer can be configured within the range of 0 ... 16383 sec in steps of
1 second.
• Unbackup Timer (Minimum none alarm event duration) in seconds: With
this timer you can configure the maximum time during which no alarm
must occur before the backup connection is released.
The timer can be configured within the range of 0 ... 32767 sec in steps of
1 second.
• Maximum Backup Time in minutes: Via this timer the maximum backup
time can be selected. The backup connection is dropped after this time,
even if the alarm signal still exists.
The timer can be configured within the range of 0 ... 32767 min in steps fo
1 minute. If you select the setting 0, the backup time is unlimited.
• Unbackup Block Gate in minutes: If a second backup connection is esta-
blished within the selected time interval, the backup connection is not dis-
connected automatically anymore. In this case, the backup connection has
to be dropped manually (by pressing the DROP button) or it is dropped
after the maximum backup time the latest. In this way, we want to make
sure that a connection which is sporadically disturbed does not trigger a
backup connection and backup disconnection permanently.
The timer can be configured within the range of 0 ... 32767 min in steps of
1 minute. If you select the setting 0, this function is deactivated and the
backup connection is dropped automatically as soon as all criteria are met.
Backup Redialling
Different redialling options are available:
• Maximum Redialling Trials (in case of ISDN error causes): Under this set-
ting you can adjust how often the decoder tries to redial, if the connection
could not be established because of an ISDN error, such as e.g. „Busy“ or
„No route“, etc.
The number of redialling trials can be adjusted within the range of 0 ... 15.
• Maximum Redialling Trials (in case of audio decoder synchronisation
lost): Under this setting you can adjust how often the decoder tries to re-
dial, if the connection can be established but the decoder does not synchro-
nize.
The number of redialling trials can be adjusted within the range of 0 ... 15.
