• Repeat dialling and blacklisting
After a failed dial attempt, the DEClaserFAX prevents a
second dial attempt to that number for 5 seconds.
Subsequent attempts are not allowed for 1 minute. Any
attempt to dial a particular number more than 15 times in 1
hour causes the number to be blacklisted. No dial attempts
are allowed to a blacklisted number until the DEClaserFAX
has been switched off and on again.
• Call clear down
If no tones are detected within 20 seconds of a call attempt,
the DEClaserFAX terminates the call attempt, goes back on-
hook, and returns to command mode.
• Congested tone
If the DEClaserFAX detects a congested tone for a
continuous period of 20 seconds, the DEClaserFAX
terminates the call attempt, goes back on-hook, and returns
to command mode.
