of the numbering plan template. This page allows you to Apply, Reset, and Reload a Numbering Plan
template, manage numbering plan pattern tables, and use the test panel to verify the numbering plan
tables. Use this mode to add or modify:
 Enterprise Country Code (ECC)—(“North America Generic” selection only)
 Enterprise extension pattern (EEP)—Pattern that defines a range of extensions within the
enterprise. For example, if you chose the United Kingdom numbering plan template when adding
an IP-PBX, the default value for the EEP is XXXX. This pattern defines any four-digit number as an
enterprise extension. If the range of extensions in your enterprise is 6000 through 6999, you can
modify the EEP to 6XXX. This pattern identifies any four-digit number starting with 6 as an
enterprise extension. If your enterprise extensions are four-digit numbers, you would need to
modify the EEP to accommodate your extensions. For example, any four-digit number starting with
70, 71, or 73 as an enterprise extension should be written as 7[013]XX.
 Enterprise Full Number Patter (EFP)—(“North America Generic” selection only - includes LAC and
LEC).
 Local area code (LAC)—Area code in which the Mobility Router is located. LAC is not defined in
some numbering plan templates (for example, France). A default value for the local area code
(LAC) is applied to a numbering plan when it is first added. You must modify the LAC so that it is
valid for your enterprise. For example, if you chose the North America numbering plan template
when adding an IP-PBX, the default LAC value is 408. If the area code for the region in which the
Mobility Router is located, change the LAC value to the appropriate area code. In some countries,
the local area code might also be known as city or dialing code.
 Local exchange code (LEC)— The local exchange code (LEC) is the prefix that is prepended to
the enterprise extension pattern (EEP) to form a valid phone number. For example, for the phone
number 9198000, the LEC is 919. A default value for the LEC is applied to a numbering plan when
it is first added. Verify that the LEC value is correct for the area in which the Mobility Router is
located. Modify the LEC value if necessary.
 Land Line Numbers (LLN)—(“North America Generic” selection only) Includes NPA and NPL.
 Mobile GSM Numbers (MGN)—(“North America Generic” selection only) Includes NPA and NPL.
 Numbering Plan Area Code (NPA)—First set of 3 digits, combined with the NPL (seven digits), that
directs telephone calls to particular region. For example, in the North American template, the NPA
first digit must not include a 0 or 1 as this causes confusion with directing a call outside the
country. The second digit must not include a 9. For example, 212 is valid, however 121 is not.
Some numbering plan templates may not use this value, such as UK.
 Numbering Plan Local Number (NPL)—Second set of seven digits, combined with the NPA (three
digits) that directs telephone calls to a particular region. For example, in the North American
template, the NPL first digit must not include a 0 or 1 as this causes confusion with directing a call
outside the country. For example, 2345678 is a valid telephone number, however 1234567 is not.
Some numbering plan templates may not use this value, such as UK.
 Outside line access code (OLC)—Number that is prepended to phone numbers when end users
place calls to phone numbers outside of the enterprise. This is also known as trunk access code.
The default value for the OLC is 9. Modify this value if is not the number that your enterprise uses
to place calls outside of the enterprise.
