System & Station
Program 72 Overview
This program defines the external Network routing numbers that can be assigned DNIS/Tie/DID
extension numbers in the Day, Day2, or Night ringing mode. This assignment will cause incoming
DNIS/Tie/DID calls to route (forward) back out over a public, or private, telephone network to a
pre-assigned telephone number.
To assign a Tie/DID line to Program 72 assignments: The DNIS/Tie/DID extension number must
be assigned to route to the appropriate Network routing number in Program 71-1.
This program can also be used with non-DNIS or ANI (only), Tie and/or DID Lines to assign
normal incoming Tie/DID calls to route back out over the public, or private telephone network to
an external telephone number.
Important!
● Tie/DID lines used for DNIS network routing must be enabled with tandem (Two-CO line)
connection with Program 15, Code 5 and Program 10-1, LED 20.
● DNIS Network routing numbers will not be restricted by DK424 Toll Restriction assignments.
● Tie/DID lines must have LED05 ON in Program 17 to use the (DID, Tie) DNIS routing
assignments in Program 71 and 72.
● DNIS network calls are timed by the Program 12 disconnect timer which, if set to default, will
disconnect the call after four minutes. The disconnect timer may be disabled
(see “Program 12 – System Assignments, Basic Timing”on Page 3-41).
