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.
To use a Walking COS code
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.
USING DIRECTORY NUMBERS
A Directory Number (DN) allows extension numbers to be used on a key basis. The
same DN may be assigned to multiple keys on the same telephone and to keys on
other telephones.
When a telephone's extension number is assigned to a key on the same telephone, it
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
