Matching Against Multiple Rules in Digit Map
A digit map normally contains more than one rules. The Digit Map Processor (DMP) must return the
best matched rule at some point, or declare that the input digit sequence is invalid. The DMP keeps
refining its decision as each digit is entered until it reaches a final decision, or is forced to make a
timely decision when the interdigit timer expires.
