Direct Station Selection, 183 | AT&T AT&T guide

Interactions

●Call Coverage: Calls to a logged-in FPDC receive the call coverage of that terminal. lJnanswered calls to a PDC at an away terminal return to the home terminal and receive the home terminal’s call coverage treatment; they do not receive the away terminal’s call coverage.

●Direct Inward Dialing: In systems with DID service, PDCs, FPDCs, DGC group

numbers, DDCs codes, and facility access codes may match the last 2, 3 or 4 digits of DID numbers. For example, the code matching DID number 555-2345 may be 45, 345 or 2345, depending on the system dial plan.

● Direct	Station	Selection:	If an attempt is made to program an FPDC (rather than
a PDC)	on a Flex	DSS button,	Reorder Tone is received.

Administration Requirements

System:

● Send DID calls to unassigned DID numbers to the Attendant - Default = Yes

● Route calls to not-logged-in FPDCs to the attendant - Default = Yes

● Add/Delete

FPDCs.

Hardware Requirements:

None
