AT800 Series User Manual
• Only one candidate sequence remains, and it has been matched completely: the number is accepted
and transmitted after any transformations indicated by the dial plan, unless the sequence is barred by
the dial plan (barring is discussed later), in which case the number is rejected.
• A timeout occurs: the digit sequence is accepted and transmitted as dialed if incomplete, or
transformed as per the dial plan if complete.
• An explicit 'send' (user presses the '#' key): The digit sequence is accepted and transmitted as dialed
if incomplete, or transformed as per the dial plan if complete.
The timeout duration depends on the matching state. White space is ignored, and may be used for
readability.
Digit Sequence Syntax:
Each digit sequence within the dial plan consists of a series of elements, which are individually matched
to the keys pressed by the user. Elements can be one of the following:
Individual keys '0', '1', '2' . . . '9', '*', '#'.
The letter 'x' matches any one numeric digit ('0' ... '9')
A subset of keys within brackets (allows ranges): '['set ']' (e.g. [389] means '3' or '8' or '9')
Numeric ranges are allowed within the brackets: digit '‐'digit (e.g. [2‐9] means '2' or '3' or ... or '9')
Ranges can be combined with other keys: e.g. [235‐8*] means '2' or '3' or '5' or '6' or '7' or '8' or '*'.
Element repetition:
Any element can be repeated zero or more times by appending a period ('.' character) to the element.
Hence, "01." matches "0", "01", "011", "0111" ... etc.
Subsequence Substitution:
A subsequence of keys (possibly empty) can be automatically replaced with a different subsequence
using an angle bracket notation: '<' dialed‐subsequence ':' transmitted‐subsequence '>'. So, for example,
"<8:1650>xxxxxxx" would match "85551212" and transmit "16505551212".
Intersequence Tones:
An "outside line" dial tone can be generated within a sequence by appending a ',' character between
digits. Thus, the sequence "9, 1xxxxxxxxxx" sounds an "outside line" dial tone after the user presses '9',
until the '1' is pressed.
Number Barring:
A sequence can be barred (rejected) by placing a '!' character at the end of the sequence. Thus,
"1900xxxxxxx!" automatically rejects all 900 area code numbers from being dialed.
Interdigit Timer Master Override:
The long and short interdigit timers can be changed in the dial plan (affecting a specific line) by preceding
the entire plan with the following syntax:
Long interdigit timer: 'L' ':' delay‐value ','
Short interdigit timer: 'S' ':' delay‐value ','
