<dialed:substituted>
For sequence substitution, use this format to indicate 
that certain dialed digits are replaced by other 
characters when the sequence is transmitted. The 
dialed digits can be zero or more characters.
EXAMPLE 1: 
<8:1650>xxxxxxx
When the user presses 8 followed by a seven-digit 
number, the system automatically replaces the dialed 8 
with 1650. If the user dials 85550112, the system 
transmits 16505550112.
EXAMPLE 2: 
<:1>xxxxxxxxxx
In this example, no digits are replaced. When the user 
enters a 10-digit string of numbers, the number 1 is 
added at the beginning of the sequence. If the user 
dials 9725550112, the system transmits 
19725550112
, 
(comma)
For an intersequence tone, enter a comma between 
digits to play an “outside line” dial tone after a user-
entered sequence.
EXAMPLE: 
9, 1xxxxxxxxxx
An “outside line” dial tone is sounded after the user 
presses 9, and the tone continues until the user 
presses 1.
! 
(exclamation point)
For number barring, enter an exclamation point to 
prohibit a dial sequence pattern.
EXAMPLE: 
1900xxxxxxx!
The system rejects any 11-digit sequence that begins 
with 1900.
*xx
Enter an asterisk to allow the user to enter a 2-digit star 
code.
S0 or L0
For Interdigit Timer Master Override, enter S0 to 
reduce the short inter-digit timer to 0 seconds, or enter 
L0 to reduce the long inter-digit timer to 0 seconds.
P
For a pause, enter P followed by a number and a space. 
The duration of the pause is the specified number of 
seconds. This feature is typically used for 
implementation of a hot line and warm line, with 0 delay 
for the hot line and a non-zero delay for a warm line.
