ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1
7-135
Called
Generally, 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.
