Understanding Ring Types; When Multiple Calls Ring An Extension; Do Not Disturb - NEC DSX PRODUCT DESCRIPTION Manual

Understanding Ring Types

The Ring Types determine how different types of calls rings extensions. Each Ring Type sounds unique
because it uses one of the 10 available ring tones. The first four Ring Types are assigned by default (see the
table below). The last two (B and C) are unassigned by default but you can assign on your phone using
Extension Override and Key Ring Override.
Ring Type
Intercom
Ring Group
Recall
Ring "A"
Ring "B"
Ring "C"

When Multiple Calls Ring an Extension

When multiple calls with different priorities are ringing an extension, the system prioritizes ringing accord-
ing to the list below. All LEDs will flash as appropriate for the type of call, but the telephone will ring only
for the highest priority call.
1. INTERCOM
2. Line Key (from lowest to highest)
3. Loop Key (from lowest to highest)

Do Not Disturb

DND permits an extension user to work by the phone undisturbed by incoming calls and
announcements.
Do Not Disturb (DND) blocks incoming calls, Off-Hook Signaling and Paging announcements. An exten-
sion user can activate DND anytime while on a call or while their phone is idle. Once activated, incoming
outside calls still flash the line keys. The user may use the phone in the normal manner for placing and pro-
cessing calls.
Do Not Disturb provides the following 4 DND options:
(1) Incoming outside calls blocked
(2) Incoming Intercom calls blocked
(3) All incoming calls blocked
