Tie Line Non-Standard Protocol Signalling (Line Access)
Description:You can program the system to respond to two types of non-standard tie line signalling
protocols. They are known as hot line and intercom dialing.
Hot Line: You can program the system for hot-line operation so that as soon as a user accesses
the tie line, the station or stations at the distant system that have access to the personal or group
intercom assigned to the hot line will ring. If you arrange for access by hot line, you must enter
the extension that will automatically ring when the tie line is seized by the calling DXP Plus. If
you do not enter an extension, the system will ring the dial 0 station, and if it is unavailable, the
system will return dial tone to the caller.
Intercom Dialing: Alternately, you can program the system for intercom dialing mode so that
as soon as users access the tie line they will hear dial tone. Upon hearing dial tone, they can
dial either a personal or group intercom number at the distant system.,
NOTE: Intercom feature codes of one DXP Plus are not available to callers from the other DXP
Plus nor can those callers access a line through the distant DXP Plus using line group
access codes.

							Automatic Number Identification (ANI) Delivery
Description:
Automatic Number Identification (ANI) is a Tl service feature for both E&M and DID lines.
Long distance common carriers offer 
ANI as a feature to dial $00 and dial 900 lines. The ANI
feature provides information to an internal telephone system that identifies the telephone
number of the calling party. Businesses served by a dial 800 or dial 900 service allow any
available user to answer the calls and have their internal telephone system process the 
ANI
information to identify the caller’s telephone number.
The common carrier supplies ANI information as DTMF digits. When the ANI feature is
combined with the Dialed Number Identification Service (DNIS) feature, the common carrier
also delimits the DNIS information from the ANI information with an asterisk (%) tone so that
the DXP Plus can process each portion properly.
The DXP 
Plus system decodes the AN1 information and sends the caller’s number to the called
telephone and to the SMDRKMDA line reports. If the called telephone is an LCD
speakerphone, its display shows the caller’s number. This display is shown for all conditions
(that is, transferred calls, call forward and so forth). The DXP 
Plus also sends the calling
number information to the SMDR/SMDA line report and makes the information available to
devices that are connected to the DXP Plus’s 
Bpen Architecture Interface @AI).
When you assign ANI to lines that callers reach by diahng access codes, the DXP P&us
processes all incoming digits as AN1 digits until it encounters the delimiter. The DXP Plus then
processes the remainder of the incoming digits as DNIS call routing digits. When you assign
ANI to lines that callers reach without dialing any digits (such as, E&M hot line or DID lines
with 0 digits expected), the DXP 
Plus processes all incoming digits as ANI digits until it
encounters the end delimiter. The DXP 
Plus then routes the call to one of the followingintercom
numbers: the one that services the E&M hot line number, the one that serves as the DID/DNIS
default, or the one that serves as the operator for the system.
The DID, E&M DNIS, and E&M tie lines all can access the Direct Inward System Access
(DISA) feature when the caller dials the DISA access code or when the DID/DNIS digits
translate to the DISA access code. The system distinguishes the DISA code from the preceding
AN1 information.
Since the DXP Plus supports AN1 only on tone dial lines, is supports both wink start and delay
start protocols but does not support the immediate start protocol.
Programming:Use the Section 8.7.2 procedure to enable DXP Plus processing of ANI information for tie lines
and program the tie line attributes.

							Call AnnounceDescription:This feature, when enabled, allows tie line callers from outside the system to voice announce
incoming calls to the DXP 
Plus station after they hear an alert tone. You must also arrange the
DXP Plus system to respond to voice announce intercom calls.
Programming:Refer to Section 8.7.2.
Dialing Mode
Description:Program the tie line to match either a DTMF tone or a rotary (pulse) dialing line as supplied by
the central office (CO).
Programming:Refer to Section 8.7.2.
Toll GroupsDescription:You must identify the tie lines that you do not want users to use when they dial toll restricted
numbers. Do this by first assigning the tie lines to toll groups and then assigning those toll
groups to the restricted number. There are 32 toll groups available for line assignment. Assign
one, several, or all lines to any desired toll group or combination of toll groups as needed. See
Section 
II for complete toll restriction programming details.
Programming:Refer to Section 8.7.5.DTMF Level
Description:Adjust the audio level of the tie line’s DTMF signals to a low (-5 db), medium (0 db), or high
(+3 db) setting. Certain sites may require a higher db level to over come line conditions that
could interfere with reliable dialing.
Programming:Refer to Section 8.7.2.
DISADescription:Enable or disable DISA capability on the tie line.
Programming:Refer to Section 8.7.2.
DISA Voice Options
Description:Use the DISA Voice Options 1 through 4 to select digital voice announce (DVA) message
levels. For example, selecting DISA voice option 2 will cause welcome greeting 2, day main
menu 2, night main menu 2, recall no answer 2, and recall busy 2 prompts to play whenever a
DISA-configured tie line is covered by DVA. Refer to Section 14.3 for complete DVA

8.8Direct Inward System Access (DISA) Programming
Through the DISA programming routines, you can configure a system to allow outside callers to call directly into
the system. DISA callers can dial authorization codes that allow them to use the system’s features that are
normally available only to inside callers.
NOTE: It is possible to use the automatic route selection (ARS) feature (Section 12) along with the DZSA feature
to route DZSA calls that pass through the system. Zf you enable this application, you may need to add
pauses in the ARS modtfj digits table (Section 14.4.4) to accountfor the time delay the system experiences
in obtaining the CO dial tone. The amount of time delay varies for each installation; therefore, you must
test your installation to determine the time required to obtain a CO dial tone when using the DZSA 
feature.
You can then adjust the system timing pause time or add multiple pauses to o$set this delay.
8.8.1DISA Cofigura tion (DISA Specific Programming)
Description:The purpose of the DISA specific programming is to perform the following tasks:
- Enable extensions where day/night DISA calls will be routed when call-routing is necessary,
- Enable proprietary voice mail to receive DISA calls and route the calls to a dedicated mailbox
that holds the appropriate intercept greetings,
- Select access Iockout time (the amount of time that the line remains locked-out from use
after invalid conditions occur-such as, when a caller repeatedly dials an invalid
authorization code),
- Select the timeout period for DISA extensions that ring without answer (RNA),
- Select the maximum timeout period for the reminder tone that sounds during an in-process
call when the DISA caller is using an outside line and the system has no disconnect
supervision. This tone sounds at set intervals to remind the caller that he or she must dial
a code (any single digit) or be disconnected within 10 seconds,
- Select the option to either route a DISA call or drop it after caller dials an invalid
authorization code

8.8.3Programming DISA Authorization CodesDescription:
DISA callers with assigned authorization codes have access to advanced system features.
Authorization codes are associated with either personal or group intercom numbers; therefore,
when a DISA caller enters his or her authorization code, the code alerts the system as to what
features to make available to the caller. Once callers access features with authorization codes,
the access remains in effect until any idle time exceeds the authorization code time-out period.
Use this programming procedure to assign or modify authorization codes and to tie the
authorization codes to accompaning intercom numbers. Use the Section 8.8.4 procedure to
assign a station class of service to the intercom numbers.

8.8.5Remote Day Exception Number/Night Exception NumberDescription:A DISA caller may have access to an outside line where the toll restriction is based on the
DISA authorization code that is associated with a particular class of service. Remote day and
night exception numbers allow DISA callers to dial numbers that their toll restriction normally
prevents them from dialing. If a toll restriction table exception number matches one of the
exception numbers that you assign using this procedure, the DISA caller is allowed to dial the
number.The exception number values that you can assign are 1 through 32 and NONE. You can assign
32 exception numbers to each DISA class of service. You also must assign one exception
number to each toll restriction table line entry (Section II. 7).

9.1Understanding Station Numbering
The system provides a maximum of 1000 intercom slots with 480 slots set up as personal intercom numbers. This
means that the system provides up to 520 group intercom numbers. All intercom numbers are four digits, and at
default, the system assigns blocks of intercom numbers in the following catagories:
1001-1480 = personal intercom numbers
400 l-4480,5000-5039 = group intercom numbers
5040-5999 = unassigned-used for renumbering purposes
6000-8999 = feature codes
Because there are no dedicated station ports in the 
DXP Plus, the system uses an automatic configuration method
to logically number its stations. Automatic configuration occurs after you perform a 
mode-+ne or mode-two
master clear on the system.
HowWith automatic configuration, the system does a search for all installed station boards in the
automatkmain and expansion cabinets, and assigns a logical number for each provided station
configurationencountered during the search. The search begins in the main cabinet at the left-most universal
worksslot and proceeds left to right. The search then moves to the upper expansion cabinet where it
searches left-most slot to right-most slot. The search finally moves to the lower expansion
cabinet where it again searches left-most slot to right-most slot. When automatic configuration
is finished, the system has logically numbered all station ports in ascending order from the
left-most slot to right-most slot throughout the entire system.
How logicalThe logical number of a station corresponds to its relationship to other stations in the system but
number andis not dependent upon the board’s placement in the cabinet. The physical location of a station
physical location corresponds to the order of the system’s board slots. The main cabinet contains slots l-9, the
relate to oneupper expansion cabinet contains slots 10-20, and the lower expansion cabinet contains slots
another21-30. Therefore, even if the first encountered station board is located in slot five of the main
cabinet, the system still assigns logical number one to the first station provided by that board.
During installation, you can skip slots. For example, you can install 16-station digital station
boards in only slots one and 30 if you wish. In this case, slot one yields logical station numbers
1-16 and slot 30 yields logical station numbers 17-32. A newly defaulted system assigns
personal intercom number 1001 to logical station one and continues in an assending sequence
until it assigns personal intercom number 1480 to logical number 480.
Adding boardsIf you install or relocate a station board, this board does not operate until you.take appropriate
withoutprogramming action (Section 15). If you use an available open slot for adding or relocating a
renumberingboard, that board’s stations assume logical numbers in sequence after the system’s last assigned
logical station number. For example, if the system’s last logical station number is 24, the logical
numbers of the newly installed board’s stations begin at logical number 25.
Logical numbers previously assigned to a removed board are available for reassignment.
Stations of an added or relocated board first assume the logical numbers made available by the
vacated slot. For example, if the system’s last logical number is 64 and you remove the board
providing stations with logical numbers 1-16, the stations on an added board assume logical
numbers beginning with 1 instead of 65. However, if you remove an eight-station board and add
a 16-station board, the first eight stations stations on the added board assume logical numbers
1-8 and the last eight stations assume logical numbers 65-72.
Remember, should you master clear the system, the automatic configuration feature logically
numbers all station ports in ascending order from the left-most slot to right-most slot throughout
the entire system. This action renumbers those stations provided by boards that you have added
or relocated since you last performed the system master clear.
