Tips about access codes

Here are some pointers to assist you in planning the access codes for your system.
Note: The following values must not conflict:
• Park prefix
• external code
• direct dial digit
• Private access code
• Public/Private Auto DN
• Public/Private DISA DN
• line pool code/destination code
• telephone DN
Note: If the line pool code and the external code start with the same digit, the
line pool code programming supersedes the external code.
External line access code:
Example: If you enter the following selections:
Park Prefix - 1
Direct Dial digit - 0
Telephone DNs - 2000-2500
You wish to add a destination code of 2500 and 12. This cannot be accomplished as this would
conflict with existing dialing numbers. To solve this you could modify the Park prefix and change
the Telephone DN of 2500.
• If the DN length is changed, and the changed DNs conflict with the external line access code,
the setting changes to None.
• Direct dial telephone: Another direct dial telephone, an extra dial telephone, can be assigned
for each schedule in Services programming.
If the DN length is changed, and the changed DNs conflict with the Direct dial digit, the
setting changes to None.
• Public/Private Auto DN: The length of the Auto DNs are the same as the Public or Private
Received Number Lengths specified under Configuration > Telephony > Dialing Plan >
Public or Private. The public/private Auto DN is cleared if the corresponding Received
Number Length is changed.
