KEYBOARD SECURITY FOR A TELEPHONE ATTENDANT CONSOLE Abstract of the Disclosure An attendant console for use with an electronic private automatic branch exchange (EPABX) includes a jack for removably connecting an attendant headset or handset to the console. A switch array in the console provides indications of attendant control action and logic circuitry connected to the switch array registers the indications. Gates are connected in series with the switch array for preventing registration of the indications in response to the attendant set being disconnected, such that control actions as may be indicated at the switch array while the attendant is away from the console are of no consequence.
