							DIRECT DIGITAL INTERFACE
NEAX2000 IVS2
Business/Hotel/Data Features and Specifications  
NDA-24271, Issue 1.0  Page 139
DIRECT DIGITAL INTERFACE
General Description
This service feature provides the capability to connect trunks from the NEAX2000 IVS2 directly to T1 carrier
links using either a private or public network.
Operating Procedure
No manual operation is required.
Service Conditions
1. Each Office Hierarchy is defined as follows:
a. Source office
One center will operate as the Source Office. This location has two highly stabilized source oscillators,
and distributes the Source Clock to all the systems through the Digital Interface lines.
b. Sub-Source office
This office operates using a Phase Lock Oscillator (PLO) to synchronize with the clock at the Source
Office. If the Source Clock fails, the Sub-Source office can operate using its own backup oscillator.
c. Receiver office
This office is arranged so it will have at least two clock routes, one for Source and the other for standby.
Synchronization Clock is derived from incoming PCM bit stream from higher hierarchy offices.
d. Local Receiver 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
2, the NEAX2400 IMX can function as a
Source office or Sub-Source office while the NEAX2000 IVS2 functions as a Receiver and/or Local Receiv-
er office.
3. Each digital office is equipped with a PLO used for network synchronization. Clocks from the Source 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 below):
a. Source - Receiver System (Source)
b. Source - Receiver System (Receiver) 
9. The maximum number of trunks for DTI is 240 ports (10 24 DTI boards:24 ports/DTI board or 8 30 DTI
boards, 30 DTI: 31 ports/DTI card). The total number of ports (DTI and other AP) must be less than 256
ports.
10. The NEAX2000 IVS
2 includes built-in PLO (Source or Receiver mode only) in the MP card.

NEAX2000 IVS2
Business/Hotel/Data Features and Specifications  
NDA-24271, Issue 1.0  Page 141
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 C.O.; however, not all telephone company C.O. are capable of pro-
viding 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 ap-
pearances 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.

2. The outside party receives ringback tone while waiting for the station to answer the Camp-On.
3. Refer to the Camp-On Features and Specifications for more information and service conditions related to
Camp-On.
DID Digit Conversion
General Description
This feature allows the system to convert the digits received from the serving C.O. to valid station numbers when
the C.O. numbering plan differs from the desired station numbering plan.
Station Application
Not Applicable.
Operating Procedure
No manual operation is required.
Service Conditions
1. Addition and deletion of digits can be implemented to coincide with the existing numbering plan.
2. When digit conversion of DID incoming LDN has been activated, the number received from the C.O. before
conversion is displayed.
3. A DID incoming LDN can be converted to a PBX station number, by analyzing the upper two-four digits
of DID incoming LDN.  A maximum of 10,000 DID incoming LDN can be converted to a maximum of
1,000 PBX station numbers.
MP without expansion memory (standard) :up to 500 station numbers

DIRECT INWARD TERMINATION (DIT)
General Description
This feature automatically routes incoming network exchange calls directly to a preselected station without At-
tendant assistance. The call can then be processed by the called party. Three-party Conference, Call Transfer,
etc., are handled in the same manner as any normal trunk call.
Station Application
All stations.
Operating Procedure
No manual operation is required.
Service Conditions
1. Bothway trunks can be used for Direct Inward Termination, but incoming only trunks are recommended.
This minimizes DIT calls meeting busy conditions.
2. If there is no answer at a station, the calling party will continuously receive ringback tone. Call Fowarding
- No Answer will occur if set or the calling party will be transferred to the Attendant or Trunk Answer any
Station by system programming if enabled.
3. Once a call is answered, it can be processed by the called station in the same way as any normal trunk call.
4. If the DIT is assigned to a pilot number of a Station Hunting group or Automatic/Uniform Call Distribution
(ACD/UCD) group, the incoming call will follow the hunt group station assignment. If the station is Call
Forwarded, the incoming call is connected to the Call Forward target station according to the types of Call
Forwarding set and the condition of the DIT station.
5. This feature is normally utilized where direct-in service is required on a limited basis. The number of sta-
tions thus serviced is limited to the number of trunks available for Direct Inward Termination.
6. Multiple trunks can be assigned to Direct Inward Terminate to an extension, but a trunk cannot be assigned
to Direct Inward Terminate to multiple extensions.
7. When the Direct Inward Termination station is busy, the call can be preprogrammed to either go to the At-
tendant, Trunk Answer any Station, or Camp-On. During night mode, the call can be pre-programmed to
Camp-On or go directly to Trunk Answer any Station.
