AT&T 1987 AT&T Telephone User Manual


 
POOLED FACILITY - DIAL ACCESS
Description
Allows both multiline and single-line voice terminal 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
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.
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.
