Thesystem processes the list of operations in ascending nOperId order(nOperId 1 first).szOperation — The name of the digit manipulation operation to perform:stripLead, stripTrail, replace, prepend, append.szValue — The value used by the operation, either the string of digits toprepend, append, replace with, or the number of digits to strip.Sample SolutionsUsing Dial PlanConfiguration FileCommandsThis section describes several requirements that a customer might have,and for each one, provides a sample solution. An explanation followseach step in the solution.For a detailed explanation of each command, see “Dial PlanConfiguration File Commands” on page 110.Customer Requirement 1. Assume that the telephone companypasses 4-digit numbers to the NBX system for each incoming telephonecall (for example, numbers in the range 5200 through 5300). If thesystem uses 3-digit extensions in the range 200 through 300, you coulddefine a single pretranslation operation that performed a stripLead toremove the first digit. For example, the system could remove the numberfive from an incoming number such as 5278, and pass the call toextension 278.To accomplish the pretranslation:PreTranslator Create 1 4-to-3-digit T1 DID/DDI PretranslatorExplanation: Create pretranslator table 1, called “4-to-3-digit T1DID/DDI Pretranslator.”PreTranslatorEntry Create 1 1 5Explanation: Create, in pretranslator table 1, entry number 1, whichapplies when the first digit in the sequence is 5.PreTranslatorOperation Create 1 1 1 stripLead 1
