Initialized Default: LEDs 12 and 14 are On
Program 10-4 Overview
This program enables various station and line features, including Call Waiting, Tie line tandem
connections, Single Line Telephone call retrieval, ISDN and LDN routing.
Important! This program also covers ACD features. See Chapter 6 of this document for
Program 10-4 ACD functions.
LED 09: Listed Directory Number (LDN) Registration (Release 4.15)
On ISDN incoming calls, LDN Registration routes unknown number or call type in numbering
plan when LED 09 is On; unknown number or call type will not route and caller hears reorder tone
when LED 09 is Off.
LED 10: Not Used
LED 11: PRI ISDN Timer
The T-Wait timer is an ISDN timer that is required to reduce the potential for a network overload
condition due to a large number of ISDN terminals requesting initialization at the same time (e.g.,
due to an area-wide power failure). This timer creates a random time interval and is called upon
power up to set a value to delay the initialization process until the timer has expired. This timer is
seldom used for PRI interfaces.
