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 ‘,’

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 timeout values.

Local Timer Overrides:

The long and short timeout 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 ‘ ‘. 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>.

These overrides are especially useful to terminate dialing in countries with predictable but variable

length numbering plans, or to provide an exception when a rule with fewer digits is known to override

a rule waiting for more digits. For example, assuming a generic international calling sequence of

011xxxxxxxxx. in North America, the PHONE ADAPTER can be configured to complete dialing to

France after the country code and exactly 10 digits using 01133xxxxxxxxxxS:0 as a dial plan digit

sequence. When this sequence matches, it overrides the short interdigit timer, causing an immediate

call. If the S:0 had been absent, the PHONE ADAPTER would wait for the short interdigit timer to

expire before placing the call.

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.

This syntax allows for the implementation of Hot-Line and Warm-Line services. To achieve this, one

sequence in the plan must start with a pause, with a 0 delay for a Hot Line, and a non-zero delay for a

Warm Line.

Implicit sequences:

The PHONE ADAPTER implicitly appends the vertical code sequences entered in the Regional

parameter settings to the end of the dial plan for both line 1 and line 2. Likewise, if Enable_IP_Dialing

is enabled, then ip dialing is also accepted on the associated line.

Maximum Length

Each dial plan cannot exceed 2047 bytes, after all configured vertical codes have been added to the

Dial_Plan parameter.

Examples:

The following dial plan accepts only US-style 1 + area-code + local-number, with no restrictions on

the area code and number.
