WALKING CLASS OF SERVICE
Walking Class of Service (COS) allows you to use your own calling privileges at
another phone. For example, you may be allowed to make long-distance calls from
your phone, but a phone in your company’s warehouse may be restricted from long-
distance calls.
To make long-distance calls from the restricted phone, you can go to that phone and
enter a Walking COS code before dialing the number.
Notes:
• Before using this feature, a Walking Class of Service must be assigned for
your phone by the system administrator of DBS 576 dealer.
• The same Walking Class of Service code may be used by more than one
extension.
1. From an extension other than your own, pick up the handset or press the ON/
OFF key.
2. Enter the walking class of service access code (default = 87).
3. Dial your extension number.
4. Enter your Walking COS code.
5. Press the # key.
6. Access an outside line.
7. Dial the phone number.
The Walking COS will remain in effect until you hang up.

is considered a Primary Directory Number (PDN). Up to three appearances of the
PDN may be assigned to keys on a key telephone. This allows for multiple calls on
the same Directory Number.
When a DN is assigned to an FF key on another telephone, it is considered a Non-
Primary Directory Number (NPDN). Up to three NPDN appearances of the same
