Capabilities
A Class of Service can be associated with a telephone, a line or
a COS password. It determines the dialing capabilities that apply
to internal telephones and any lines used for external calls.
Users have a Class of Service associated with their telephones,
in the sense that there are dialing filters associated with
telephones, as line assignments. Use of a COS
password affects only the telephone’s dialing capabilities.
The ability to change the COS internally means that someone
using another person’s telephone can temporarily change the
restrictions that would normally be applied.
Password security
Class of Service passwords for a system should be
determined randomly, and should be changed on a regular
basis.
System users should memorize their COS passwords
instead of writing them down.
Employees’ COS passwords should be deleted when they
leave the company.
Programming hints
A system can have a maximum of 19 six-digit COS
passwords (00 to 18).
You can copy the data from one COS password to another
COS password number using the display button in the
same way that telephone and line data can be copied.
COS passwords must be
unique.
Programming COS passwords
Use the button, the display button, and the
dial pad to program the six-digit sequences for each password.
Use the
BKSP
display button to edit digit sequences you have
entered.
