Chapter5 Parameters and Defaults
Optional Feature Parameters
For example, to enter an interdigit timeout of 12 seconds and discard dialed digi ts unless 911 is entered,
you would use the following command:
Ic| 911
Specifying your own interdigit timeout also changes the behavior of the dial plan so that the entire dial
string, rather than being sent at timeout, is sent only as a result of a matching rule or time intended by a
matching rule.
'H' Rule to Support Hotline/Warmline
Hotline/Warmline, also known as Private Line Automatic Ringdown (PLAR), is a line used for priority
telephone service. If the Hotline feature is configured, the Cisco ATA immediately dials a pre-configured
number as soon as the handset goes off hook. If the Warmline feature is configured, the CiscoATA dials a
pre-configured number if no digits were entered before the specified timer value expired when the handset
went off hook.
Syntax
Hdnnnn
where d is a delay-in-seconds parameter 0-9,a-z (to support 0 to 35 seconds delay), and nnnn is the
variable-length phone number to call when no digits are ente red for d seconds after the handset goes off
hook.
•Example 1: H05551212 (Hotline configuration; the Cisco ATA immediately dials 555-1212 when the
handset goes off hook.)
•Example 2: H55551212 (Warmline configuration; the CiscoATA waits for five seconds and dials
555-1212 if no digits were entered when the handset went off hook.)
'P' Rule to Support Dial Prefix
This rule is for automatic pre-pending the dial string as entered by the user with a specified prefix.
Syntax
Ptnnnn
where t is a single leading trigger character; if t is the first entered digit when making a new call, it
triggers the prepending of a variable-length prefix (as specified by nnnn) in the dial string. The t
character can take one of the following values:
0-9,*,#, 'n' (= any of 1-9), 'N' (any of 'n' and 0), 'a' (any of 'n',* and #), or 'A' (any of 'a' and 0);
Example:
Pn12345: Prepends 12345 to the dial string when the first entered digit is any of 1-9. The triggered di git
is not removed from the dial string.
