Distinctive Ringing
Users sometimes need to distinguish the ringing of one button on their phone from another button
and sometimes stations in close proximity to one another need to distinguish the calls on one desk
from another. Typically, multiple sounds are used to provide this distinction. Strata CTX offers
four different tones. Three of the tones are different pitches of a common sound and a fourth, a
combination sound, is provided for a very distinguishable sound. Distinctive ringing can be
assigned to each
/LQH or [DN] button on each telephone.
The four distinct tones sound when the button rings with incoming outside line calls. Internal and
transferred calls have another unique tone that applies to all buttons on all telephones.
Do Not Disturb (DND)
Station users with digital telephones can activate DND to prevent any calls from ringing their
telephone. Callers will hear a fast busy tone when calling stations in the DND mode. Stations in
DND mode can originate calls normally; however, they receive DND stutter dial tone when
originating calls. Call Forward-Busy will forward calls directed to a telephone with DND set, even
if the telephone has idle [DNs]. Telephones with DND Override capability can ring DND
telephones (see Do Not Disturb (DND) Override on page 60).
Direct Station Selection (DSS) Buttons
[DSS] buttons can be placed on digital telephones, add-on modules and DSS consoles. When
placed on one of these devices, these buttons serve two functions: to make direct calls or transfer
calls to other stations; and to display the status of other stations and [PDNs].
The [DSS] button is numbered with a stations [PDN] and when pressed, calls that [PDN]. [DSS]
buttons are not [DN] buttons, so they do not provide dial tone when pressed. The [DSS] button
LED shows the status of the station and [PDN] it represents (idle, busy, DND or ringing). The
[DSS] LED will turn on steady or flash at a unique rate, depending on the status (see [DSS]
Button Status Display.
The [DSS] LED displays the telephones status for any type of call on any button, including
[PhDN] and
/LQH buttons. The [DSS] LED also indicates the status of the stations [PDN] itself. If
the [PDN] appears as a Secondary DN [SDN] on multiple telephones, the DSS status will display
Busy if any telephone is using the [SDN].
