(key) Numbering plan parameter key, which is a three-letter
code and surrounded by parentheses, used in
numbering plan table patterns.
When specifying a numbering plan parameter key in a
numbering plan pattern table, make sure to include
parentheses. Specifying only the three-letter code is
not valid. Only use parentheses in conjunction with a
key; parentheses used in any other context are not
valid in a pattern.
The following lists the default numbering plan
parameter keys:
EEP—Enterprise extension pattern
LAC—Local area code
LEC—Local exchange code
NPA—Numbering plan area code
NPL—Numbering plan local
OLC—Outside line access code
For example, to include the national number code
parameter in a numbering plan table pattern, specify
(NNC) as part of the pattern. Note the special bracket
type for this parameter is ( ).
In addition to above default numbering plan parameter
keys, the following built-in variables are automatically
expanded with the appropriate value at run-time.
o EEN - User’s Enterprise Extension Number
o EFN - User’s Enterprise Full Number
o CNM - User’s Cellular Number
Built-in variables are enclosed in curly braces "{}". For
example {EEN} expands to the Enterprise Extension
Number of the user in call.
