Features and Services
Pooled Facility - Direct Access
Description
This feature allows multiline voice terminal users to access a common pool of trunks via a Direct
Facility access (FACILITY) button.
Upon pressing a FACILITY button and going off-hook, a multiline voice terminal user is connected
to a common pool of outside trunks (i.e., CO, FX, WATS, tie). If the Status and I-Use LEDs
associated with the button light steadily, the user may complete the call. If no idle trunk is available
(facility busy indication), an attempt by the user to originate a call will be denied and the I-Use
indicator will be Off. A user requiring access to several different trunk pools must have a separate
FACILITY button for each pool.
If all trunks in a pool are busy, the Status LED will be lighted. The user may press FACILITY and
remain on-hook to receive the busy-to-idle reminder when a trunk becomes available. The busy-to-
idle reminder is a short burst of tone that will be heard when a trunk in the pool becomes available.
When Prime Line Preference is assigned to a FACILITY button, the button must be pressed to
invoke the busy-to-idle reminder, even though the I-Use LED is lighted.
Refer to the “Trunk Groups” feature description for additional information.
Considerations
Pooled Facility-Direct Access provides easy access to the exchange network for users who make
many outside calls. The feature eliminates the need to dial a facility access code. In addition, the
associated status LED provides pool busy/idle status and the busy-to-idle reminder.
Interactions
The following features interact with Pooled Facility-Direct Access.
Automatic Route Selection (ARS): Multiline voice terminal users who have presses FACILITY to
activate busy-to-idle reminder must wait until all queued ARS users have been serviced.
Equal Access: Equal Access calls are allowed from toll-restricted stations that have outward
calling capability via pooled facilities (701 and 801 trunks) administered with “ORIGINATING LINE
SCREENING.” Originating Line Screening is a service provided by the Local Exchange Carrier
(LEC), identifying the call as one which should not have the operator bill the originating facility.
Facility Access Restriction (see “Calling Restrictions”): A trunk group may be reserved for a
group of users by dial-access restricting the trunks. In this way, only users who have a FACILITY
button, a Personal Line appearance, or who use ARS can use the trunks.
Line Selection (Prime Line Preference): Pressing a FACILITY button to invoke the busy-to-idle
reminder overrides Prime Line Preference.
Toll Restriction (see “Calling Restrictions”): Toll-restricted voice terminals receive standard toll-
restriction treatment on all FACILITY buttons.
