Do Not Disturb (DND)
System Availability: All systems
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 (optional)
when originating calls. With Release 1.3 and higher, users can disable DND stutter dial tone (1/2
sec. burst of busy tone before dial tone) in programming.
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 88).
Direct Station Selection (DSS) Buttons
System Availability: All systems
[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 station’s [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 telephone’s status for any type of call on any button, including
[PhDN] and
Line buttons. The [DSS] LED also indicates the status of the station’s [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].
[DSS] Button Status Display
Red, steady: Busy on a call not connected to your telephone
Green, steady: Busy on a call connected to your telephone
Red, quick flash rate: Ringing
Red, slow flash rate: Do Not Disturb
DTMF Receivers
System Availability: All systems
DTMF receivers are used when receiving incoming DNIS DID, Tie or DISA line calls and when
originating calls with standard tone-dial telephones. Voice mail systems also require DTMF
receivers for a number of VM features, even if using SMDI or Toshiba Proprietary VM
integration. Four circuits are automatically active with the initial basic processor. Activation of
more than four receivers requires the purchase of a DTMF software license, in four-circuit
increments.
DTMF receivers require an optional ARCS subassembly on the CTX100 processor and are built
into the CTX670 processor. For the number of receiver circuits, refer to
Table 12 on page 26.
