Comdial Dxp Plus Instructions Manual

							Toll Restriction
With the toll restriction feature, the system allows or denies outgoing line calls to selected users over
selected lines. Toll restriction meets different dialing needs by allowing users to dial numbers that they
are required to dial yet restrict them from dialing numbers they are not allowed to dial. Toll restriction can
be used together with the automatic route selection and call costing features if desired, or used separately
as a stand alone feature or not used at all.
The programmer assigns toll restriction to stations based on system requirements. Telephones that are not
assigned this feature are free to dial any number their users choose to dial. Plus, a toll restricted station
can dial any telephone number that it is not restricted from dialing. If a station is restricted from dialing a
certain telephone number on a certain line, it can, if programming permits, dial that number on another
line that is not restricted. Further programming action specifies whether or not toll restriction applies to
system speed dial numbers. The programmer can also differentiate between day toll restrictions and toll
restrictions that only take effect in night mode. A defaulted system imposes no toll restriction on any
station.
The toll restriction feature first compares a dialed number to a matching assigned restricted number up to
the last digit in the assigned number. At that point it considers it a match and applies other toll restriction
tests whether the station user keeps dialing or not. If all toll restriction tests are met, the station is not
normally allowed to dial the number. There are 32 exception number test matches assigned to the station.
Exception numbers allow stations to dial numbers that they are not normally allowed to dial by their toll
restriction.
Toll Restriction Pause Entries
When this feature is activated by installers, they can enter a pause at the end of a restricted number’s digit
string to indicate that dialing is complete. They do this by typing a P or p after they type the digit string.
The pause entry distinguishes this restricted number as unique. They can enter the same digits without the
pause but instead followed by additional digits as another unique number. They can assign different
routing and toll restriction parameters to each of these entries. There are several applications for this
feature. One application is in international dialing where different toll restriction parameters apply
depending upon whether the caller dialed 0 or 011. In this case, installers can enter 0 pause to access local
lines and 01 to access international lines. Another application is with tie line calling where a remote
extension is the same digits as an office or area code that installers need to enter in the restriction table.
By entering nnn pause for tie line access and nnn@ for CO line access, the system can route the call over
the proper line. A third application is brought forth with the advent of the new North American
Numbering Plan (NANP). With NANP, an area code may be the same digits as a local office code.
Installers can enter nnn@@@@ pause for local line access and nnn@@@@@@@ for long distance line
access (the @ is a match anything character). In any application, the system resets its pause timer after
receiving each caller dialed digit. If the timer expires before the caller dials another digit, the system
routes the call based on the digits preceding the pause. If, instead, the system detects more digits instead
of a pause, it routes the call based on the entire digit string.
Tone On Hold
This feature gives you an alternative to providing music or no music for callers who are placed on hold.
When you program this feature into the DXPPlussystem, both internal and external callers hear a pattern
of short tone bursts while they are on hold. The patterns consist of two 1/10-second tone bursts separated
by 1/10-second. These tone patterns repeat every five seconds.
The installer enables this feature and assigns it to particular trunks through line programming or stations
through class of service programming using the PC. The system manager can also select this feature from
the applicable class of service from a programming station for intercom calls placed on hold. The choices
when programming this feature are: music from source one, music from source 2, tone on hold, or nothing.

							Tone Or Voice Signaling On Internal Calls
Intercom number calls can be tone signaled or voice signaled as desired.  Programming determines which
signaling method the system uses as the primary method when an intercom number call is made. Users
can choose the alternate method at the station by pressing the intercom key. Intercom number call
progress is marked by special tone signals.
Tracker Paging System
The Tracker Paging System interfaces a DXP system with individual Tracker pagers. The Tracker Paging
System informs users through their Tracker pagers that they have a call waiting for them. The Tracker
base station connects to any of the DXP system’s serial ports or to the PC Attendant position. The DXP
can accept up to four Tracker base stations supporting up to 600 Tracker pagers. Many different types of
Tracker pagers are supported—from those with numeric displays to those that display a pre-programmed
message up to 32 alphanumeric characters long.
Creating Messages From The PC Attendant
Up to eight default messages can be programmed and delivered from the PC Attendant position only (see
theDigital Communications System PC Attendant’s Console User’s Guide, GCA 70-230 for instructions).
The PC attendant can be in either thelocalor thesystemmode of operation.
RNA Or Busy Tracking
If the called station fails to answer or is busy, the caller can activate the Tracker Paging System by
pressing the TRACK button on his or her telephone. The TRACK button is one of the telephone’s
interactive buttons. On telephones not equipped with interactive buttons, the caller activates the Tracker
Paging System by dialing the Tracker access code (defaults toS8). When the call is accepted, the caller
will hear a confirmation tone, or if it is not accepted, a busy tone.
Direct Tracking
The caller can also do direct paging by pressing the TRACK programmed button or by dialing the
Tracker access code (defaults toS8). The telephone prompts the caller with its display to enter the
assigned extension number for the pager along with the display messageEnter Ext:
Transfer Tracking
If the system attendant attempts to transfer a call to an extension that does not answer (or is busy) and
then activates the Tracker pager assigned to that extension, the incoming call is placed on a page orbit.
Once the system places the call on a page orbit, the user’s Tracker pager displays the orbit number so that
he or she can retrieve the call by dialing the number of the orbit containing the call. If the user does not
retrieve the call within the pre-programmed time-out, the call returns to the attendant. The Tracker Paging
System supports up to 100 page orbits.
GCA40–130 DXP Plus General Description
110 – Understanding The Features 
						

							Using Voice Mail With Tracking
When a caller reaches an extension with an assigned Tracker pager, and that extension is covered by
proprietary voice mail, the system may prompt the caller to either select the assigned Tracker pager or
leave a message. If the caller selects the Tracker pager, the system places the call in a page orbit, and
displays that page orbit number on the user’s Tracker pager. The user retrieves the call by dialing the
number of the page orbit containing the call. After a pre-programmed time-out, the call is returned to the
proprietary voice mail where the caller can leave a message.
Accessing The Tracker Pager From DISA
The Tracker Paging System is accessible from DISA by using the DVA voice messages.
Programming Options
There are three levels of programming associated with Tracker operation.
The installer or programmer performs the DXP system level using a PC. Programming at this level
installs Tracker operating parameters and pager-to-intercom assignments that can only be changed at this
programming level.
The PC attendant level of programming, available when the PC attendant position is installed, operates in
one of two modes–local or system. In the local mode, the attendant assigns pagers to intercoms and
selects pager types. This programming is transparent to the DXP system and does not alter any Tracker
programming done at the DXP system level. In the system mode of operation, all Tracker operating
parameters and pager-to-intercom assignments are as programmed into the DXP system by the installer or
system programmer.
The system manager level of programming allows the system administrator to use a programming station
to select a Tracker base station and enable or disable the Tracker Paging system.
Transfer/Conference Button
Each multiline telephone and proprietary multiline telephone provides a fixed button that gives quick,
easy transferring and conferencing of calls.
Transfer Recall
Refer to the discussion titledTimed Recall.
Transfer Ring Cadence
A telephone user can select the ringing cadence that announces a transferred line call. They have two
choices as follows: one cadence provides a 2 sec. on—4 sec. off tone, the other cadence provides a 0.5 sec
on—5.5 sec. off tone. The programmer can choose either cadence as the default setting.

							V
Voice Mail Integration Digits
Installers can choose the DTMF digits that the DXPPlussends to a voice mail system. A voice mail
system uses these DTMF digits to determine system and station status so that it can properly process a
call. Installers must be versed in the voice mail’s requirements before they can assign DTMF integration
digits in the DXPPlus. The system defaults the voice mail parameters to match the Comdial voice mail
system. Certain applications in countries with dialing plans different than the United States may require
different integration digits. The default digits are shown in the following list and discussed below:
Follow Extension ID = 2 Intercom/Answer Confirmation = 1
Busy = 2 Do Not Disturb = 3
Incoming Intercom Answer = 9 Disconnect = A
Follow Extension ID – When the voice mail system receives a forwarded call from a ring no-answer
(RNA) or busy station, the DXPPlussends to the voice mail system the extension number of the
forwarded call followed by this DTMF digit (n). The DXPPlussends this digit within 500 ms of the time
the voice mail system answers the call. For example, if extension 101 is forwarded to voice mail and
voice mail answers a forward RNA or busy forwarded call, the DXPPlussends 101n to the voice mail
system within 500 ms of the answer time.
Intercom/Answer Confirmation – The DXPPlussends this DTMF digit to the voice mail system to
confirm that an intercom path (without dial tone) is available for the voice mail system’s call transfer or
dialing use. The DXPPlussends this digit within 500 ms of the time it detects the voice mail system’s
off-hook or hookflash condition. The DXPPlusalso immediately sends this digit to the voice mail system
when a station answers a voice mail transferred call. This action can alert the voice mail system to
disconnect and leave the parties connected.
Busy – If the voice mail system transfers a call to a station that is busy on a call, the DXPPlussends this
DTMF digit to the voice system. When the voice mail system receives this digit, it can abandon the
transfer, reconnect to the call, and offer the caller whatever options the the voice mail system has
available in its programming. If the DXPPlusauto attendant transfer on busy feature is active, the DXP
Plus will not send the DTMF digit to the voice mail system thus allowing the system to transfer a second
call to the station.
DND – If the voice mail system transfers a call to a station that is in the do not disturb (DND) mode, the
DXPPlussends this DTMF digit to the voice system. Receiving this digit allows the voice mail system to
distinguish between a busy and a DND condition and offer the caller the appropriate choices.
Incoming Intercom Answer – The DXPPlussends this DTMF digit to the voice mail system when a
station user makes an intercom call to the voice mail system. This action allows the voice mail system to
distinguish between internal and external calls and offer the caller appropriate prompts and dialing
options.
Disconnect – When an outside line or intercom party hangs up, the DXPPlussends this DTMF digit to
the voice mail system to command an immediate disconnect. For outside calls, the central office (CO)
must provide disconnect supervision to the DXPPlusand the installer must program the DXP Plus line
for abandon hold release and disconnect supervision. At default, the DXPPlussends the DTMF tone for
the A character as the disconnect digit. Since a caller cannot dial an A from a telephone. This feature
eliminates callers from causing an accidental disconnect by dialing this digit on their telephone’s dial pad.

							Voice Announce Blocking
This feature allows the user of multiline telephones to block voice announced intercom calls by dialing a
special code or by pressing a programmed button.
Z
Zone Paging
This feature arranges for stations to transmit and/or receive voice announcements to and from a particular
group of stations or to all stations. This feature also arranges for all-call and zone paging to an external
paging device. The programmer can assign stations to particular paging zones, up to eight zones, to
permit station users to make announcements to one particular site, or he or she can assign all stations to
the same zone to permit users to announce all areas at once.

							Installing The
DXP Plus Main Common Equipment Cabinet
1.0 Installing The Common Equipment Cabinet
1.1 Considering The Mounting Parameters
·Choose a suitable location.
4A suitable location is within four feet of a proper electrical outlet. (The main cabinet and two expansion
cabinets requires two dedicated 117VAC 15 AMP circuits, with a third-wire ground, supplied to standard
NEMA 5-15R electrical outlets. Each outlet must be supplied from the opposite phase of the AC power line.
4A suitable location provides a distance between the common equipment and the TELCO/PBX jacks of 25
feet or less as per FCC requirements. (Good engineering practices recommend a nominal distance of 7 feet.)
4A suitable location allows enough room between the top and bottom of the main cabinet and the ceiling or
floor of the equipment room for placement of one expansion cabinet above and one expansion
cabinet below the main cabinet.
4A suitable location is secure and dry and has adequate ventilation. The temperature range of a suitable
location is within 32–122 degrees F (0-50 degrees C), and the relative humidity is less than 90 percent
non-condensing .
1.2 Inventorying The Tools And Hardware
·Round-head wood screws (typically1/4x 1–inch for mounting equipment cabinet to backboard)
·Round-head wood screws (typically1/4x11/2–inch for mounting backboard to wall studs; longer screws are
necessary if fasteners must also pass through a dry-wall covering)
·Cross recessed screwdriver (phillips-head type)—to match front panel shipping screws
·Flat blade screwdriver—to match front panel retaining screws
·Electric drill—if prepared holes are required
·Connecting tool—for fastening wires to a type–66 connector block.
·Crimping tool—for 623-type modular plugs
·Static discharge wrist strap and conductive floor mat
1.3 Complying With Underwriters Laboratories Regulations
Per The Underwriters Laboratories regulation 1459, 2nd edition, be aware of the following precautions when
installing telephone equipment that is to be directly connected to the telephone company network:
·Never install telephone wiring during a lightning storm.
·Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
·Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
·Use caution when installing or modifying telephone lines.
