POOLED FACILITY - DIRECT ACCESS

Description

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

Automatic Route Selection (ARS): Multiline voice terminal users who have pressed FACILITY to activate busy-to-idle reminder must wait until all queued ARS users have been serviced.

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.
