X. Digit map
The CA may request the gateway to collect the dialed digits. For example, the MRS
collects the dialed number or the credit card number. In this case, the CA loads a digit
map to the gateway. Like a numbering plan, the digit map collects all the numbers,
and then sends the digits in a message. This helps to save the network resources.
This digit map is expressed using a strict syntax. It is composed of a list of digits and
letters. If collected dial sequence matches one of the defined strings, it indicates
necessary digits have been collected. What are supported in the definition of digit
strings include the digits from 0 to 9, the letters from
A
to
D
, the pound sign (#), the
asterisk sign (*), the letters
T
and
x
, and the dot sign (.). The digit strings separated by
| are alternative number schemes. The brackets ([]) indicates any of them. The
asterisk sign (*) indicates the digits are reported one by one if * is dialed. The letter
T
indicates the timer is detected timeout. The letter
x
indicates any digit. The dot sign (.)
indicates any number of letters, including zero number of letters, can appear before it.
The pound sign (#) indicates to report the digits immediately.
For example, we can dial the following numbers using a phone.
