Features and Services
Pooled Facility - Dial Access
Description
This feature allows multiline and single-line voice terminal and ATL cordless telephone users to
access a common pool of trunks by dialing a facility access code.
Up to 16 facility access codes can be assigned (one per trunk group). The codes can be one to four
digits in length. A group of similar trunks assigned the same access code is referred to as a trunk
group. Additional information is provided in the “Trunk Groups” feature description.
After going off-hook on a System Access or Loop button, receiving system dial tone, and dialing a
facility access code, the user will be connected to an idle trunk. (However, the connection will not
be made if the terminal is restricted from dialing this trunk group or if dial access is restricted, in
general, to trunks in the group.) The LEDs associated with the System Access button will be lighted,
and the user may complete the call. Single-line users do not receive LED indications of the status
of the pool. An attempt to originate a call on a busy facility will result in Reorder Tone (fast busy).
Considerations
Pooled Facility-Dial Access provides users of single-line terminals, or multiline voice terminals
without Direct Facility Access (FACILITY) buttons, access to the system’s pooled facilities.
Interactions
The following features interact with Pooled Facility-Dial Access.
Bridging of System Access Buttons: A station originating a call on a Bridged Access button and
using a facility access code is granted access to that pool according to the Calling Restrictions
assigned to the bridging station, not the principal station.
Direct Inward Dialing (DID): Access to pooled facilities via DID is permitted. This includes access
to WATS, FX, tie trunks, private lines, dictation equipment, and paging systems. This access is
provided by selecting facility access codes so that they will match DID numbers.
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.
Outward and Facility Access Restriction (see “Calling Restrictions”): A terminal can be denied
dial access to some or all pooled facilities, or may be totally restricted from making any outside
calls.
Toll Restriction (See “Calling Restrictions”): Denies the use of pooled facilities for certain toll
calls, but does not block access to the pooled facilities.
