A-30Basic features

Power Failure Transfer

Provides service to and from the local telephone company central office, including

Wide Area Telecommunications System, during a power failure. This allows users

to make or answer important or emergency calls during a power failure. This

feature is also called Emergency Transfer.

Priority Calling

Allows a user to ring another telephone with a distinctive signal that tells the called

party that the incoming call requires immediate attention. The called party can

then handle the call accordingly. A user activates priority calling by dialing a

Priority Calling access code or by pressing a feature button, followed by the

extension number. A user can use Priority Calling only if the telephone has been

administered with the required class of service.

Privacy — Attendant Lockout

Prevents an attendant from reentering a multiple-party call that is being held on

the console unless the attendant is recalled by one of the parties on the call. This

feature is administered on a system-wide basis and is either activated or not

activated.

Privacy — Auto Exclusion

With Auto Exclusion active, the Manual Exclusion feature can be automatically

activated on a class-of-service (COS) basis. If the COS for Automatic Exclusion is

set to yes, then exclusion is automatically activated when you go off hook on a

telephone set which has an Exclusion button assigned.

With Automatic Exclusion active, a held exclusion call can be taken off hold by

any telephone user with an appearance of the extension that put the call on hold.

Privacy — Manual Exclusion

Allows multi-appearance telephone users to keep other users with appearances

of the same extension number from bridging onto an existing call. Exclusion is

activated by pressing the Exclusion button on a per-call basis.

Public Network Call Priority

Provides call retention, forced disconnect, intrusion, mode-of-release control, and

re-ring to switches on public networks. Different countries frequently refer to these

capabilities by different names.
