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 Meridian 1 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 Meridian 1 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 (i.e., Collect Call Blocking Allowed
Class of Service or option)
New classes of service and prompts have been introduced to inhibit specific
users from receiving collect DID and Central Office calls. These can be
configured for the following:
• PBX and BCS through the Collect Call Blocking Allowed/Denied
(CCBA/CCBD) option
• Attendant and Network Alternate Route Selection calls on a per customer
basis through CCBA/CCBD option
• Automatic Call Distribution (ACD) queues through the CCBA prompt
