Day/Night Class of Service D-15
D-15  Day/Night Class of Service
General Description
This feature permits any station to be assigned one CLASS OF SERVICE - INDIVIDUAL [C-15], for day and
another for night. System data can be programmed so that once the ATTENDANT CONSOLE [A-3] has entered
the NIGHT CONNECTION [N-1,2] mode, a stations CLASS OF SERVICE - INDIVIDUAL [C-15] will be
automatically changed when required. Class may be upgraded or downgraded, and trunk groups normally controlled
by the Attendant in the daytime may be opened to station control in the night mode.
Operating Procedure
This feature is controlled entirely via the ATTENDANT CONSOLE [A-3]. Pressing the NITE key or removing the
handset changes the service class. Releasing the NITE key or replacing the handset restores normal CLASS OF
SERVICE - INDIVIDUAL [C-15].
Service Conditions
1. DAY/NIGHT CLASS OF SERVICE may be assigned on a per tenant and per station basis.
2. DAY/NIGHT CLASS OF SERVICE may be assigned to different trunk restriction and service restriction
classes.
3. Refer to CLASS OF SERVICE - INDIVIDUAL[C-15]for further details.
4. Night mode restriction classes can be set at any time by entering the related command on the
MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
5. When TENANT SERVICE [T-12] is provided with MULTIPLE CONSOLE OPERATION [M-4], the
system can be programmed for either all ATTENDANT CONSOLEs [A-3] or primary ATTENDANT
CONSOLE [A-3] to control activation of DAY/NIGHT CLASS OF SERVICE.
6. When DAY/NIGHT mode changeover occurs, tenant number, day/night mode of the tenant, status of the
external switch, and cause of changeover are printed out on the alarm printer and MAT printer. (This
service is determined by system data.)
7. Day/night information of the unused tenant is not printed out.
8. A maximum of 14 tenants information can be printed per message.
9. An example of printout format is shown below:

Service Conditions (cont’d)
10. When the Attendants NITE key or external switch is turned ON and OFF repeatedly, the messages printed
out and the operation may not coincide, but the system message will represent the final day/night mode.
11. In the following cases, day/night mode is not changed when the external switch is turned ON, and only the
system message is printed out:
a.) When neither the ATTENDANT NIGHT TRANSFER [A-19] or TAS [T-8] is available, SYS2
Index 13 b1=1 (no check by Attendant at the time of day/night mode changeover), and the NITE
key of Attendant indicates Day.
b.) When neither ATTENDANT NIGHT TRANSFER [A-19] or TAS [T-8] is available, SYS2 Index
13 b1=0 (check by Attendant at the time of day/night mode changeover), and the NITE key of
Attendant indicates Night.
12. When day/night mode changeover is activated by jack at the time System Data is SYS1, Index 77 b0=1
(day/night mode changeover by jack available), the cause of changeover is indicated as NITE key (=1).
13. This feature is to be controlled by the Attendant Console accommodated in the terminating node for the
FCCS network.
14. Day/Night mode is changed by the destination node of the operator call assigned system data for the FCCS
network.
Note
15. The node which does not accommodate the Attendant Console controls DAY/NIGHT mode of the self-
node using the external key for the FCCS network.
16. The user can assign only one destination node from a node, even when the system is organized by more
than one tenant.
Note:The following Attendant Console Day/Night Mode Change methods are determined by system data: By the
Primary Attendant Console / By all Attendant Consoles
Interactions
1. When assigning station data, assign the restriction classes desired to cause the station to upgrade,
downgrade, or remain unchanged status of restriction class when going from Day to Night. If DAY/
NIGHT CLASS OF SERVICE is not required, assign the commands normally.
2. The DAY/NIGHT CLASS OF SERVICE arrangements are based on the day/night operating status of the
tenant.

D-16  Direct Digital Interface
General Description
This service feature provides the capability to connect trunks from the NEAX2400 IPX 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.

Direct Digital Interface D-16
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 IPX 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: 31
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:AO PR- 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.

D-31 Delay Announcement - UCD
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.
