Class of Service Changeover
Your telephone may be set up at the CBX to use one
class of service (the primary) during normal business
hours and then automatically change over to a more
limited one (the secondary) during non-business
hours. This arrangement makes it more difficult for
someone to use your telephone to make unauthorized
calls.
The Class of Service Changeover feature lets you
enter your personal identification number (PIN) to
temporarily restore your telephone’s primary class of
service during non-business hours, giving you access
to all of the calling features you normally use. When
you are done, you can return to your telephone’s
secondary class of service. Or, if configured at the
CBX to do so, your phone will return to its secondary
class of service after a preset period of time.
