eration, device status information and alarm information recording which can be accessed from the Maintenance
Administration Terminal (MAT) or Customer Administration Terminal (CAT).
Station Application
Not applicable.
Operating Procedure
Refer to the NEAX2000 IVS Maintenance Manual for operating procedures.
Service Conditions
1. The following station status information can be displayed on the MAT or CAT by direct command.
• Idle
• Line Lockout
• Dialing
• Tone Trunk Connection (reorder tone, busy tone, service set tone, etc.)
• Types of Connection, (station to station, three way calling, voice calling, holding, etc.)
• Destination number (trunk number, register number)
• Short circuit on line
2. The following trunk status information can be displayed on the MAT or CAT by direct command:
• Idle
• Ringing in
• Incoming queue to Attendant Console
• Holding
• In a tandem connection
• Incoming queue to UCD
• Dialing
• Receiving dialed digits
3. The following information is stored and can be displayed on the MAT or CAT using a memory dump com-
mand in hexadecimal format:
• Program address where an endless loop has occurred.
• Last initialization time for main program.
• Last initialization time for firmware program.
• The reason for initialization (power-on, RESET key, endless loop, sense switch, command from MAT
or CAT).
4. The NEAX2000 IVS has a built in patrol program that monitors the status of all connected devices.  Addi-
tionally, when no response or an invalid response from a device is received, this program stores in memory
the slot number of that device.  From the MAT or CAT a maintenance person can read the slot number of
any device which does not respond to the Main Processor or provides an illegal status to the Main Processor.

Dial Conversion
Dial Conversion
General Description
The system can be assigned to use rotary Dial Pulse (DP) or Dual Tone Multifrequency (DTMF) trunks and sta-
tions.  This feature provides for the repeating of digits dialed by the station user onto the C.O. trunks.
Station Application
All stations.
Operating Procedure
Normal call handling procedures apply.
Service Conditions
1. Trunks are assigned for DP and/or DTMF on a trunk route basis.
2. Single Line Telephone (SLT) circuits are assigned for DP and/or DTMF through station Class of Service
for the station number assigned to the circuit.  The Single Line Telephone circuits can accept 10 or 20 PPS.
3. The system will automatically provide Dial Conversion when the station is a DTMF SLT and dialing is be-
ing done on a DP trunk.
4. The system can be assigned to provide DTMF dialing on trunks for Attendant Consoles only, while gener-
ating rotary dial pulsing for station dialing.
5. For an outgoing call on a trunk once the outgoing register times out (6 seconds after the last digit is dialed),
further digits dialed out by a Multiline Terminal will be DTMF and the duration of the tones will be the same
as the length of time the dial pad key is depressed.  This feature allows Multiline Terminals to send DTMF
signals to external equipment such as computers and other dial up services.
6. The dial pulse make ratio is programmable for 33% or 39% (default is 39%).  The dial pulse interdigit pause
can be set from 300 ms to 900 ms (in increments of 100 ms) or 1100 ms (default is 800 ms).
7. The DTMF signal width is programmable for 64ms or 128ms (default is 64ms).  The DTMF interdigit pause
can be set for 32, 64, 80, 96, 160, 192, or 240 ms (default is 96 ms).

Direct Data Entry
General Description
This feature allows a maid or other hotel personnel to enter numeric data to the PMS (Property Management
System), using the guest room station for entry through dial operation. The same numerical data can be output
to a Hotel/Motel Printer by system data programming.
Station Application
All stations.
Operating Procedure
1. Lift the handset and receive dial tone.
2. Dial the Direct Data Entry access code and receive feature dial tone.
3. Dial input data to the PMS or Hotel/Motel Printer, and receive service set tone.
4. Restore the handset.
Service Conditions
1. This feature is activated from a guest room telephone.
2. The digit 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 can be used for the input data.
3. The input data can be sent out to the PMS and/or Hotel/Motel Printer.  The output option can be selected by
system data programming.
4. A maximum of 30 digits can be entered in one operation to the PMS and/or Hotel/Motel Printer. If data ex-
ceeds 30 digits, the guest room station receives reorder tone.
5. If the input data to be sent is less than 30 digits, “#” can be used to end the digit string.  (The “#” is not sent
to the PMS and Hotel/Motel Printer.)
Example: Access code + 1234567890#
6. When the Hotel/Motel Printer is used, “*” can be used to separate the data entry (“*” is not printed out, but
is sent out to the PMS). In this case, the input data including “*” shall be up to 30 digits.
  Example: Access code + 001*002*12345*3#
7. Reorder tone will be received instead of service set tone if the PMS does not respond within 15 seconds or
sends a negative answer to the NEAX2000IVS.

Direct Digital Interface
Direct Digital Interface
General Description
This service feature provides the capability to connect trunks from the NEAX2000 IVS directly to T1 carrier
links using either a private or public network.
Operating Procedure
No manual operation is required.
Service Conditions
1. Each Office Heirarchy is defined as follows:
a) Master office
One center will operate as the Master Office.  This location has two highly stabilized master oscillators,
and distributes the Master Clock to all the systems through the Digital Interface lines.
b) Sub-master office
This office operates using a Phase Lock Oscillator (PLO) to synchronize with the clock at the Master
Office.  If the Master Clock fails, the Sub-Master Office can operate using its own backup oscillator.
c) Slave office
This office is arranged so it will have at least two clock routes, one for Master and the other for standby.
Synchronization Clock is derived from incoming PCM bit stream from higher heirarchy offices.
d) Local slave office
This is the end office in a digital network arrangement.  This office will not be provided with a backup
route for the PLO because this office is the only one influenced in the event of trouble occurrence.
2. When a digital network is implemented using the NEAX2000 IVS, the NEAX2400 can function as a Master
Office or Sub-Master Office while the NEAX2000 functions as a Slave and/or Local Slave Office.
3. Each digital office is equipped with a PLO used for network synchronization.  Clocks from the Master Os-
cillator or Digital Interface Package should be connected to inputs on each PLO. 
4. D3 Channel Banks are not required since the switch can be equipped with a Digital Trunk Interface (DTI)
compatible with DS-1 signal level.
5. The DTI provides signalling interface, bipolar/unipolar conversion, frame synchronization, insertion/ex-
traction and alarm detection.

6. The DTI can be provided with circuit cards to interface with T1 carrier.
7. The DTI boards are mounted in the AP board slot of the Port Interface Module (PIM).  
8. The following two methods may be used for network synchronization (see Figure 2 below):
a) Master - Slave System (Master)
b) Master - Slave System (Slave) 
9. The maximum number of trunks for DTI is 120 ports (24 DTI: 24 ports/DTI board or 4 30 DTI boards, 30
DTI: 31 ports/DTI card).  The total number of ports (DTI and other AP) must be less than 128 ports.  A
maximum of 5 (24 DTI) boards  may be installed in the system.
10. The NEAX2000IVS includes built-in PLO (Slave Mode only) in the MP card.  If the system is to be used
as a Master, a PN-CK00 (PLO) card is required.
11. The PLO card (PN-CK00) is mounted in the AP slot of Port Interface Module 0 (PIM0).

Direct Inward Dialing (DID)
Direct Inward Dialing (DID)
General Description
 This feature provides for incoming calls from the exchange network (except FX or WATS) to reach any station
within the system without attendant assistance.
Station Application
Not applicable.
Operating Procedure
The calling party outside the system dials the appropriate telephone number.  The call will ring directly at the
called station, bypassing the attendant.
Service Conditions
1. This feature is normally used when direct in service is desired on an extension or system-wide basis.
2. DID must be provided by the serving Central Office; however, not all telephone company Central Offices
are capable of providing this service.
3. One of  the following control signaling methods can be used on incoming DID trunks: immediate start, delay
start and wink start.
4. Dual-Tone, Multi-Frequency (DTMF) or rotary dial signaling is available.  This is assigned on a trunk route
basis.
5. Calls to invalid numbers can be routed to an Attendant, a predesignated station, or to a recorded announce-
ment.
6. When a station has activated Call Forwarding (all types), the DID call will be forwarded to the designated
station rather than to the specific station dialed.
7. If the called station is assigned as a pilot in  Station Hunting and is busy, the call follows the preset hunting
pattern.
8. On an incoming call to a busy station, the Call Forwarding feature takes precedence over the Station Hunting
feature.  If the Call Forwarding feature and the Station Hunting feature are not activated, the caller will re-
ceive busy tone or will reroute to the Attendant Console, predesignated station, or recorded announcement
depending on the assignment in system programming.
9. Stations in Do Not Disturb will be provided with visual indication but no audible indication.  Secondary
appearances will ring when assigned.  The calling party will receive ring back tone until answered.
10. An incoming Listed Directory Number (LDN) received from a DID line can be displayed on the LCD of a
Multiline Terminal or an Attendant Console.  This system data is assigned on a trunk route basis.
11. The DID incoming LDN display is one digit to four digits.
