ONT Product Information Guide
This example:
• Allows for multiple digits to be entered following * or # for service codes
• Nested parentheses and parenthetical grouping is not allowed. A single pair of
parens delimits the complete digit map
• The interdigit timeout with this digit map should be configured to 4 seconds
(normally it is 16 seconds).
Matching rules
Take the default dial plan as an example:
(***xx|*xx*x.#|*xx*x.*xx#|*xx*x.*x#|*31*xxxxxxxx|*xx#|#xx#|*#xx#|#00
1|x.T)
• If one unique item is matched without ambiguous, ONT would sent the dialed
numbers immediately. e.g. dial *43#
• If the matched item contains timer T, ONT would wait for sending until the timer
expired. If a new digit is dialed before the timer expires, ONT will re-check the
dialed number with the new digit to see if the number can be sent out. e.g. dial
123456
• If the dialed numbers do not match any items, ONT would not send the numbers.
e.g. dial ***#
• If the numbers dialed hit more than one item, ONT would chose the best match
one.
e.g. (***xx|123xxx.T|1234)
• After dial 1234, ONT would send out the numbers immediately as the rule 1234
was hit instead of 123xxx.T
Dial timer configuration
You can configure dial timer behavior:
<PermanentTimer>20</PermanentTimer>
<InterDigitTimer>16</InterDigitTimer>
<CriticalTimer>4</CriticalTimer>
• PermanentTimer indicates how long the dial tone would play when the subscriber
went off-hook but didn’t dial any digits
• InterDigitTimer indicates how long the ONT would wait for the subscriber to
continue dialing when a number was dialed but did not fully match any item of
the dial plan
• CriticalTimer indicates how long the ONT waits after some numbers are dialed
that match one item of the dial plan. It is only applicable to the item with postfix T
