553-3001-306 Standard 10.00 January 2002
Flexible Line Lockout-This feature provides three options for lockout
treatment for stations and DISA calls. Flexible Line Lockout can perform any
of the following functions:
• provide the existing overflow tone and then lockout treatment
• immediately intercept calls to the attendant, or
• receive overflow tone and then intercept to the attendant.
When a call is intercepted to the attendant, ringback is returned and the call
appears at the Attendant Console on a designated Line Lockout (LCT)
Incoming Call Indicator (ICI) key. If an LCT ICI key is not defined, the call
is treated as a normal incoming call.
When the attendant answers the call, the Directory Number (DN) of the
originating telephone, followed by the name (if Call Party Name Display is
enabled), is displayed on the console. The attendant may then terminate the
call or offer assistance to the call originator.
Flexible Line Lockout Timers – This enhancement to Flexible Line Lockout
provides three variable Line Lockout timers. The timers are defined in
overlay 15, and range from 0 to 60 seconds.
Operating parameters
TIE trunk calls do not receive overflow tone during Line Lockout, and do not
receive Flexible Line Lockout treatment.
