The SPRE Pattern table index. This must be in the form of a SPRE code or dialing pattern containing wildcards. Available wildcards for this index are: N=2-9, M=1-8, X=0-9, [abc]=Any digit contained in the bracketed list. Ending the pattern with '&' will cause the unit to also look for a valid dial-plan pattern following the SPRE code, however ending it with '$' will cause the unit to stop attempting to match further input. The following rules must be observed: 1. Template must begin with a * or #. * and # are not allowed elsewhere in the template. 2. Templates MUST have at least one NUMBER. 3. ( ) and - are allowed, but not inside braces [] 4. Wildcards (MNX) are not allowed inside braces [], only numbers - order of numbers is not enforced, but ranges are not allowed. 5. & or $ is allowed but MUST be the last character. Cannot be standalone.
