and

Now we will create an example digit map using a few of the rules above. One important function of a digit map is to
determine if the user has entered sufficient digits during dialing, given the array of number combinations available, a
digit map normally contains more than one rule. To create a digit map that includes a few of the example rules in the
table, we write our digit map contained with brackets ( ) and with each rule separated by a | bar as follows:
(<1408> xxx xxxx | @. 408 890 6000 | xx.<#> | !08[47]x. | !09x.)
