Element Repetition

Any element can be repeated zero or more times by appending a period (.) to the element. Thus, "01."
matches "0", "01", "011", "0111", ... and so on.

Sub-sequence Substitution

A sub-sequence of keys (possibly empty) can be automatically replaced with a different sub-sequence
using an angle bracket notation: < dialed-subsequence : transmitted-subsequence >. So, for example,
"<8:1650>xxxxxxx" would match "85551212" and transmit "16505551212".

Inter-sequence Tones

An "outside line" dial tone can be generated within a sequence by appending a comma (,) 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:
•
•
Thus, "L:8,( . . . )" would set the interdigit long timeout to 8 seconds for the line associated with this
dial plan. And, "L:8,S:4,( . . . )" would override both the long and the short time-out values.

Local Timer Overrides

The long and short time-out values can be changed for a particular sequence starting at a particular point
in the sequence. The syntax for long timer override is: L delay-value<space>. Note the terminating space
character. The specified delay-value is measured in seconds. Similarly, to change the short timer
override, use: S delay-value<space>.

Pause

A sequence may require an explicit pause of some duration before continuing to dial digits, in order for
the sequence to match. The syntax for this is similar to the timer override syntax: P delay-value <space>.
The delay-value is measured in seconds.

– Ranges can be combined with other keys: e.g. [235-8*] means 2 or 3 or 5 or 6 or 7 or 8 or *.
Long interdigit timer: L : delay-value ,
Short interdigit timer: S : delay-value ,
