This feature automatically cuts off calls on certain lines after a preprogrammed time. The system will not
cut off calls made to an emergency number. The system sounds a warning tone at the busy station 10
seconds before it disconnects the call. The warning tone consists of one 800 ms burst followed by eight
100 ms bursts.

Tie lines; these are typically the three line types that the central office (CO) makes available for
connection. The...

N
Names (Station And Lines)
The programmer can name every station and line connected to the system for identification and
programming purposes. On an LCD speakerphone, the name of called and calling stations appear in the
display. When a user selects a line for use or when it is ringing on a call, the line name appears in the
LCD speakerphone display.
Night Service Automatic Switching
The programmer can arrange the system to automatically enter and exit the night transfer (of ringing)
mode of operation...

Originating Denied
The programmer can deny users the ability to originate calls on certain lines or intercom numbers at
certain stations. Originating denied does not prevent a user from answering a ringing line, retrieving a
held call or receiving a transferred call.
Out-Dial Delay Time
With speed dialing, it is sometimes necessary for the system to wait a short time after selecting a line and
before dialing the number. This wait period gives the telephone company switching equipment time to
prepare to...

PBX/CENTREX/Central Office Compatible
System features and programmable buttons support the requirements of most PBXs, Central Offices, and
CENTREX systems. Users can make numbers, #,T, programmable pauses, and flash signals a part of
every stored number for access to host system feature codes.
PC Attendant
Refer toAttendant Position, PC.
Periodic Line Tone
This feature provides periodic warning tones to station users while they are busy on certain lines. The
warning tone consists of one 500 ms burst, a...

Printer Interface
The system makes a wide variety of printout records available through a serial data port provided by a
communications card. The programmer can direct these printouts to the SMDR/SMDA data printer or to
the screen of the programming PC. Also refer to the discussions titledCommunications Card Support and
Serial Data Port.
Privacy
Refer to the discussion titledAutomatic Privacy.
Privacy Release
The programmer can assign a privacy button to a telephone. If a line has privacy release...

Pulse/Tone Switchable
If the installation site is in an area that supplies rotary (pulse) dialing lines from the central office instead
of, or in addition to, tone (DTMF) dialing lines, the programmer can match the dialing mode of the line
port to that of the line.  If a rotary dial line is matched, further programming action matches the system
with the pulses-per-second rotary dial signaling of the line. The system defaults the line ports to match
tone dialing lines.
On those occasions when a user needs...

Remote Programming And Diagnostics
Programmers can program the DXPPlussystem from a personal computer (PC) running the visual man
machine interface (VMMI) program. The PC can be connected directly to the maintenance port on the
services board or connected by modem through the public telephone network. For remote programming to
take place, an installer must connect the DXPPlusmodem between the maintenance port on the services
board and an outside telephone line, and connect a customer-supplied modem...

Ring Back Tone
By default, when callers call an intercom party, they receive an intercom ring back tone to tell them that
the called intercom station is ringing. Also, when they call over the CO line, they receive a CO-style ring
back tone to tell them that the distant CO telephone is ringing. Some system users find intercom ring back
tone confusing. When installers encounter this situation, they can take this programming action to assign
CO-style ring back tone to intercom calls on a system-wide basis....

Serial Data Port
The DXPPlusprovides two serial data ports on the CPU board and dedicates them to PC-based
programming and the remote maintenance modem. The installer can add up to 16 additional serial data
ports to the system for interfacing such items as open architecture interface applications, PC attendant
positions, and the SMDA data printer. He or she adds these serial data ports by installing communications
cards on the services board, the expansion cabinet interface board, and the main cabinet’s...
