ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1 7-135

CalledGenerally, this field only specifies some of the leading digits that are contained in

Number the called-party number IE. The digits received must match, on a digit-per-digit basis, what is administered in this field. Field encodes and their descriptions are:

●A series of numbers, which may consist of from 1 to 16 digits, corresponding to the required leading digits.

NOTE: If this field is administered then the associated Called Len field must also be administered.

●No entry, leave the field blank. This will suffice for the case where the digits received are not significant.

Del	The digit Del and	digit Insert fields (together) provide the ability to do digit
	manipulation/digit	replacement on incoming calls. It is the manipulated number
	that is used to route the call.

The Del field specifies the number of leading digits to be deleted from the Called Party Number IE. Once the specified number of digits have been deleted, the digits specified in the Insert field are prepended to the front of the Called Party Number. Field encodes and their descriptions are:

●A series of numbers, which may consists of from 1 to 16 digits, corresponding to the leading digits that are to be deleted. This administration option may be used to solve many of the problems relating to cross dial plan mapping.

Application Example #1

If the called-party number IE contains a 4 digit number (that uniquely identifies an extension or hunt group) but does not align with the required address because the switch has a 5 digit dial plan. Then, the appropriate leading digit may be inserted so that the call will route correctly.

Application Example #2

If the called-party number IE contains the digits [8123] or [8567] but it is desired to route these calls to hunt groups with extensions [44123] and [44567] respectively. Then, the screen would have an entry for each number, and the Del fields would contain a one and the Insert fields would contain the digits 44.

NOTE: The number of digits deleted cannot be greater than the number specified in the Called Len field.

●No entry, leave the field blank. When no digits are to be deleted.

●The word all. This option may be used to route particular types of calls to a specific extension number. This specific extension number would be administered in the Insert field.
