Page 96 of 504 Attendant consoles
553-3001-367 Standard 3.00 August 2005
Emergency Transfer
If a major equipment or power failure halts local call processing, preselected
CO trunks are automatically connected to preselected stations (predetermined
and hard-wired at installation time) through relays in the system. Emergency
Transfer can also be activated manually by a switch underneath the attendant
console.
If the switch is activated while the console has power, the word
“EMERGENCY” appears on line 4 of the display.
Attendant Administration
Attendant Administration is an optional feature that allows the attendant to
modify some of the features assigned to selected telephone sets within the
attendant’s customer group. The attendant can enter a special program mode
with an assigned key.
Once in the program mode, the console key/lamp strips have different
functions from those during normal call processing. A plastic overlay can be
placed over the console keyboard to identify the altered key functions. Refer
to Features and Services (553-3001-306) for Attendant Administration
description and operating procedures.
Collect Call Blocking
The Collect Call Blocking feature enables a system administrator to block
long distance collect call service calls on incoming Direct Inward Dialing
(DID) and Public Exchange/Central Office trunks (analog or DT12).
Under the following conditions, the system sends a special answer signal to
the Central Office to indicate that collect calls cannot be accepted:
• The Collect Call Blocking (CCB) package 290 is enabled.
• The incoming route has CCB enabled via the CCB prompt in the Route
Data Block.
• The call is answered by a CCB user (that is, Collect Call Blocking
Allowed Class of Service or option).
