Direct Digital Interface D-16
D-16 Direct Digital Interface
General Description
This service feature provides the capability to connect trunks from the NEAX2400 IMX directly to “T1” carrier links
via either private or public network.
Operating Procedure
No manual operation is required.
Service Conditions
1. The DTI provides signalling interface, bipolar/unipolar conversion, frame synchronization, insertion/
extraction and alarm detection.
2. The Digital Interface Module can be provided with circuit cards to interface with “T1” carrier and/or
CCITT standard networks.
3. The Digital Interface Module (DTI) is mounted in a Port Interface Module (PIM).
4. The following two methods may be used for network synchronization:
a.) Source-Receiver System (Source)
b.) Source-Receiver System (Receiver)
5. 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.

Service Conditions (cont’d)
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 has some failure, 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 Receiver
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
an event of trouble occurrence.
6. Each NEAX2400 IMX can be equipped with a duplicate Phase Lock Oscillator used for network
synchronization. Each PLO has 4 inputs to which clocks from the Source Oscillator or Digital Interface
Module should be connected.

RT:  3 1
5-TF :3 6-TCL :1 7-L/T :1 8-RLP :2 9-TQ :1
13-AC :1
STEP 3:AT R K - Assign the LENs, DIRECT DIGITAL INTERFACE Trunk Route Number, Trunk Number,
and Tenant Number.
STEP 4:MBTK - Assign the make idle status to the DIRECT DIGITAL INTERFACE trunks.
STEP 5:ANPD - Reserve a number level for Register Sender Least-Cost Routing (LCR). This level should
correspond to the station numbering plan of the opposite office. Assign Connection Indexes, CI = N,
H; Normal and Hooking. Number of Necessary Digits will be the length of the digits in the opposite
office’s station numbering plan.
STEP 6:ASPA - Assign the access code of the LCR flag route. Type of Service, SRV = LCR (Least Cost Route
Selection), LEAST COST ROUTING-3/6 DIGIT [L-5]. Assign Connection Index, CI = N, H; Normal
and Hooking. Assign the LCR flag route number associated with this access code.
STEP 7:ARNP - Assign the physical route numbers as assigned in ARTD, and relate these routes to the LCR
access code as assigned in ASPA for SRV = LCR (Least Cost Route Selection). The LCR access code
is the first digit of the opposite offices’ station numbers.*
Note:
These same routes may also be listed in ASPA for SRV = OGC (Outgoing Call). In that case, these routes may also be
available via direct dial access codes, but are not assigned for LCR in the ARNP command.
STEP 8:AMND - Assign the maximum necessary digits the system must translate for proper route selection. In
this case, assign the first digit of the other system’s station numbering and the number of digits in the
station numbering plan.
STEP 9:AFRS - List the dialing patterns in groups that are served by a specific sequence of routes. Use only
the DTI routes and the first digit of the station numbering. Assign this dialing sequence to an OPR.
STEP 10:AOP R - The AFRS command designates the dialing sequence and the OPR to be selected. The AOPR
defines the routes and in what order these routes will be selected. In this case, only the DTI routes will
be assigned. Assign the following parameters:
TDC No. (TDPTN) - Time-of-Day Pattern Change. Usually, this parameter does not apply, and data
“0” must be entered. For an AFRS assignment, however, if different OPRs will be required as a
function of time, designate which Time-of-Day Pattern Change Number (TDPTN) OPR is assigned (0
-7).
OPR No. (OPR) - Outgoing Pattern Route, the number referenced in AFRS consisting of a series of
routes to be chosen based on the dialed number.
Route Advance No. (RA) - The order in which a route will be selected (0-7). Usually only one or two
routes are involved with DTI TIE Lines.
Route Advance End Display (E) - The last route in the route advance group. Indicate with data “0”.
All other routes are indicated by data “1”.
Route Number (RT) - The physical Route Number to be selected, as programmed in ARTD.
Skip Digits (SKIP) - Do not skip any digits. Usually the LCR access code is the opposite system’s
station level. This digit must be sent to the opposite PBX.
Pattern Number Location (PNL) - If digits are to be added after translating the dialed digits in AFRS,
use AADC command. This is usually not applicable.
Overflow Tone (OVFT) - Assign if a tone is wanted for the Last Choice Route. If so, assign data “1”
for DDD. Usually not applicable.

Delay Announcement - UCD D-31
D-31 Delay Announcement - UCD
General Description
This feature provides recorded announcement service for an incoming call directed to a busy UNIFORM CALL
DISTRIBUTION (UCD) [U-1] group and placed in a waiting queue. The recorded announcement occurs after a
predetermined time in the queue.
Operating Procedure
No manual operation is required.
Service Conditions
1. Up to eight announcement machines can be assigned per UCD [U-1] group.
2. The DELAY ANNOUNCEMENT-UCD time consists of three time periods. Each idle time period
requires a duration of 6 seconds:
a.) before the announcement (idle time) 
b.) the announcement
c.) after the announcement (idle time).
3. After the announcement is played, MUSIC ON HOLD [M-7] is activated.
4. Ringback tone is sent to the queued UCD [U-1] call before the first DELAY ANNOUNCEMENT begins.
5. If programmed, the DELAY ANNOUNCEMENT can be repeated while the incoming call is waiting in
the queue. Between each announcement, MUSIC ON HOLD [M-7] will be heard.
6. When a UCD [U-1] station becomes idle, the incoming call is connected immediately to the idle station,
even if the incoming call is connected to the DELAY ANNOUNCEMENT-UCD.
7. If the incoming call comes from a ring down trunk, billing begins with the start of the Delayed
Announcement.
8. If an incoming call encounters all stations busy in a UCD [U-1] group and overflows to another UCD [U-
1] group, and if all stations are busy in the OVERFLOW - UCD [O-13] group, the calling party will be
placed in the queue for the originally called UCD [U-1] group, and DELAY ANNOUNCEMENT - UCD
will be invoked, if programmed.
9. The figures below show Delayed Announcement Time Charts for a single programmed announcement,
and for a repeated programmed announcement.

D-32D Dual Hold - Dterm
D-32D Dual Hold - Dterm
General Description
This feature allows two Dterms to simultaneously be placed on hold. This allows the held parties to answer or
originate a call from a subline appearance or the idle prime line.
Operating Procedure
To place a call in a DUAL HOLD-Dterm condition:
1. When two Dterms are connected, either Dterm user can press the pre-assigned HOLD key and place the
other Dterm on hold.
2. If the held D
term user wishes to originate or answer another call from a sub-line appearance, the held Dterm
user presses the pre-assigned HOLD key and places the connection in a DUAL HOLD-Dterm condition.
To place back to the original connection:
1. The Dterm user goes off-hook and presses the held line.
2. The held D
term hears MUSIC ON HOLD [M-7] if originally connected Dterm is still holding the call.
3. The held D
term comes back to the original call if originally connected Dterm has already returned to the
original call.
Service Conditions
1. The DUAL HOLD - Dterm feature can be activated by pressing the HOLD key during a call between any
two Dterms.
2. While a call is being held, Automatic Recall is initiated after a preprogrammed time on the D
term that
placed the call on Hold.
3. For STATION MESSAGE DETAIL RECORDING SYSTEM [S-10] information between extensions, a
call is regarded as completed when the HOLD key is pressed to hold the call. When both stations answer
the held call, it is processed as a new call.
4. Even in the case of a call between two D
terms, DUAL HOLD - Dterm cannot be initiated between Boss and
Secretary after the Boss/Secretary service, or between overriding and overridden parties after the
PRIVACY RELEASE [P-18] service.
5. This feature is not restricted by the Class of Service for the stations in the network.
6. The following services are available to either the holding line or the line placed on hold when a call is held
by pressing the HOLD key in a DUAL HOLD - D
term situation:

D-87 Dial Intercom
D-87 Dial Intercom
General Description
This feature gives multiple Dterm users the ability to simultaneously call any other member of the intercom group,
regardless of their idle or busy status. An intercom group member can override another intercom station in a two-
party intercom connection. This service is referred to as an Intercom Bridge.
Operating Procedure
To originate a DIAL INTERCOM call:
1. The intercom station presses the DICM key and goes off-hook within five seconds.
2. Dial the desired INTERCOM telephone number; receive ringback tone. The calling D
term displays:
3. The desired INTERCOM station answers the call and is connected to the calling station.
To answer a DIAL INTERCOM call: 
1. The DICM key will flash, indicating an incoming DIAL INTERCOM call. The called station may also
hear distinctive three-burst ringing. The called Dterm displays: 
2. If the called station is already engaged in a conversation with a non-intercom call, the station may press
the HOLD key and answer the DIAL INTERCOM call by pressing the DICM key. Ringing will stop.
To bridge into a DIAL INTERCOM call:
1. When two stations are engaged in a DIAL INTERCOM call, a third station, belonging to the same DIAL
INTERCOM group, presses the DICM key and goes off-hook. The called and calling Dterms display:
2. A three-party conference is established. The called stations may hear a Warning Tone. The option for
