4. For more detail, refer to ETI: 010, Dterm IV, V Asynchronous Data Adapter - Installation and
Programming.
5. Switched Synchronous Communication Using The DT-003 Data Module:
Typically, switched (dialed) synchronous connections are attached to computers using Half Duplex
protocols. In most cases where a Half Duplex protocol is used, the DM has to be set for Full Duplex (via
SW0) because the NEAX2400 IMX provides a Full Duplex link. This will normally not affect the Half
Duplex protocol handshaking.
Internal:Internal switched synchronous connections can be provided up to 56 Kbps.
T1:
a.) Over T1, a switched synchronous speed of up to 48 Kbps can be provided using the 8DST (PA-
8DSTB) circuit card.
b.) With T1 synchronous communication between two NEAX2400s, one of the sites must be a
Primary or Sub Primary (PLO-A); otherwise, slips will occur, increasing the Bit Error Rate.
c.) At the NEAX2400 IMX secondary site, T1 (24DTI) cards are connected via a PLO card to derive
Primary Clock from the network in priority order. If priority is set up incorrectly, or if two
primary clocks are coming in, slips may occur which will not cause a T1 error, but will cause
improper data synchronization. Also, Zero Suppression (ZCS) using the 24DTI switch setting
must be turned ON (SW1-3UP).
CCIS:
a.) With CCIS, switched speeds up to 56 Kbps can be provided when bit stealing is not used by the
24 DTI and associated T1 facilities.
b.) In order to have switched synchronous data at 56 Kbps with CCIS, a 24DTI (PA-24DTA-B or
higher) circuit card is required. Switched synchronous data at 56 Kbps is not presently provided
on the 8DST circuit card.
Nailed Down Connection:
Internal:
a.) When the nailed down connection is within the NEAX2400 IMX, use the AFCD command to set
EAD Data as follows:
 EAD-A: Originating Station - 00-DT-003 or DA-007
 EAD-B: Terminating Station - 00-DT-003 or DA-007
Internal Nailed Down connections can be provided up to 56 Kbps 
(Note 2).
T1:
a.) When the connection is over a T1 channel, use the AFCD command to set EAD Data as follows:
 EAD-A: Originating Station: 00
 EAD-B: Terminating Station (T1 channel): 05
The above must also be programmed at the second site.
Note 1:
The AFCD command will not work unless SYS Data 1, Index 60, Bit 4 is set to 1 (Fixed Connection in service).
Note 2:
Nailed Down connections up to 56 Kbps over T1 channels can be used, as long as the PAD selected in the AFCD
command for the T1 channel is 5.
Switched Connection Via The 24 DIT:
a.) The routes used for communication with the DT-003 Data Module via the 24DTI are
programmed in ARTD:
 CDN 45:A/D = 1 (Digital Line Data)
 CDN 30:PAD = 5 (for Bit Stealing - reverses order of DO and S bits)
Setting Attributes 02, 03, & 10 Via DTE Keyboard:
a.) Cable connections and switch settings on the PA-4DTLA card must be performed before these
attributes are set.

b.) Voice and data must both be idle. Turn OFF power to the Data Module. Move the SW3 switch to
the right (ON), then turn power back ON. The Data Module will enter Menu Mode.
c.) The initial menu will appear on the DTE display. Enter “5” (Attribute data) to the INPUT NO.?
prompt. Input the parameter number (02, 03 or 10) when the INPUT NO.? prompt appears again,
then enter the data for that parameter. After entering the required data, enter RETURN to go back
to the menu display.
d.) To return the Data Module to the idle state, enter “0” (End) while in Menu mode, then move the
TEST2 switch to the left (OFF).

Supervisory Call - CCIS S-73
S-73 Supervisory Call - CCIS
General Description
This feature allows an Attendant, in a CCIS network, to set Supervisory Call status before releasing a Central Office
call to a station. When the call is extended to a station, the loop will remain up until the called station answers. This
overrides ATTENDANT LOOP RELEASE [A-6] on a per call basis.
Operating Procedure
To activate a SUPERVISORY CALL - CCIS from the ATTENDANT CONSOLE [A-3]:
1. The Attendant answers an incoming Central Office call.
2. The Attendant extends the call to the desired station. 
3. The Attendant presses the SP SET key; the HOLD lamp corresponding to the loop will light. 
4. The called station and incoming call are connected. 
5. The called station switch hook flashes; the HOLD lamp on the ATTENDANT CONSOLE [A-3] flashes
at 60 IPM. If an Attendant position is available, an audible indication will be provided.
6. The Attendant presses the associated loop key to return to the called station; the calling station is placed
on hold (MUSIC ON HOLD [M-7]).
Service Conditions
1. If the Attendant enters a loop that is already set up for a SUPERVISORY CALL - CCIS, the service is
automatically cancelled and a three-party connection is established.
2. SUPERVISORY CALL - CCIS is not provided for station-to-station intra-node calling.
3. SUPERVISORY CALL - CCIS can be provided on a TENANT [T-12] basis.
4. A station at which SUPERVISORY CALL - CCIS has been activated will automatically recall to the
Attendant if that station switch hook flashes.
5. If the incoming Central Office call or the station releases during the SUPERVISORY CALL - CCIS, the
loop becomes idle at the ATTENDANT CONSOLE [A-3].
6. When the Attendant answers a recalled SUPERVISORY CALL, the service is complete. If the call is to
be extended to another station, SUPERVISORY CALL - CCIS can be re-established.
7. SUPERVISORY CALL - CCIS is provided for inter-node station-to- station calling in a CCIS network.
8. The SUPERVISORY CALL status will also provide simultaneous SERIAL CALL [S-15] [S-52] service.
9. The following services are restricted while this service is activated:
AUTOMATIC CAMP-ON WITH TONE INDICATION - CCIS [A-45]
BUSY VERIFICATION - CCIS [B-9]
CALL HOLD [C-6]
EXECUTIVE RIGHT-OF-WAY  [E-8]
Interactions
SUPERVISORY CALL - CCIS is normally used in a loop-release ATTENDANT CONSOLE [A-3] setup, so that
calls that are normally released from the Attendant loop can be monitored on a per-call basis.

T-26 Toll Restriction - 3/6-Digit - CCIS
T-26  Toll Restriction - 3/6-Digit - CCIS
General Description
This feature allows the NEAX2400 IMX to restrict outgoing calls through CCIS according to specific Area and/or
Central Office codes. This restriction is determined on the basis of a three-digit Area Code or six-digit Area and
Office Code numbering plan.
Operating Procedure
No manual operation is required.
Service Conditions
1. The programmed restriction pattern can consist of codes to be allowed or codes to be restricted.
2. TOLL RESTRICTION - CCIS is assigned on a CLASS OF SERVICE - INDIVIDUAL [C-15] basis.
3. The system can be programmed to ignore digit “1” prefixing in an area code pattern.
4. When a toll call is denied, the calling party receives reorder tone. If desired, the calling party can be routed
to the ATTENDANT CONSOLE [A-3].
5. A Restriction table is assigned to each trunk group.
6. Tandem calling does not override TOLL RESTRICTION - 3/6-DIGIT - CCIS.
7. TOLL RESTRICTION - 3/6-DIGIT - CCIS is assigned on a TENANT [T-12] basis.
8. Through Dialing Feature: The Through Dialing feature does not override the Toll Restriction feature.
9. The Toll Restriction feature is assigned on a per-line Class of Service basis. When provided, the feature
is applicable on a per-trunk group basis.
Interactions
1. When Toll Restriction is specified in ARRC, all possible dialing patterns must be assigned in ATDP. If
office codes within an area code do not need to be restricted, allow the area code only. Always provide the
system with the most economical configuration of digits when constructing TOLL RESTRICTION tables.
2. In the ARRC command, ARI-A-RES must be programmed to allow two trunks and a station in a
conference. ARI-D-RES is programmed if the two trunks are to remain connected after the station drops
off or if TOLL RESTRICTION applies to a direct trunk-to-trunk connection such as a Tie line to DDD.
3. ROUTE ADVANCE [R-6] - Station A dials a toll call by accessing route 1. Route 1 is busy and advances
to route 2. Station A is restricted from making this call on route 2. The call will be restricted.
4. PASSING DIAL TONE [P-2] - The ATTENDANT CONSOLE [A-3] cannot use the PASSING DIAL
TONE feature to allow a TOLL RESTRICTED station to use a restricted route.
5. OUTGOING TRUNK QUEUING [O-2] - When a station is restricted from all other routes, a station may
use this feature to queue a trunk to complete a call over the unrestricted route(s).
6. LEAST COST ROUTING [L-5] - Transactions in AFRS must be such that the digits dialed in the trunk-
to-trunk connection should be recognizable in terms of choosing a route. If a route cannot be chosen,
TOLL RESTRICTION 3/6-DIGIT cannot be applied.

Trunk Answer from Any Station - CCIS T-27
T-27  Trunk Answer from Any Station - CCIS
General Description
This feature allows any station not restricted from incoming calls to answer incoming calls when the network is in
Night mode.
When this feature is activated, incoming Central Office calls will activate a common TRUNK ANSWER FROM
ANY STATION (TAS) signal. By dialing a specified code, any station may answer the call and extend it to any
other station in the CCIS network using CALL TRANSFER - ALL CALLS - CCIS [C-50].
Operating Procedure
To answer an incoming call: 
1. The TAS signal sounds indicating an incoming call. 
2. Lift the handset and receive dial tone. 
3. Dial the TAS access code; the incoming call is connected.
Service Conditions
1. An incoming call terminating in the Night mode will be forwarded to the TAS equipment of the
terminating node.
2. An incoming call to the main node in the Night mode will not be forwarded to TAS equipment in a satellite
node through the CCIS network. Therefore, the main node must provide TAS equipment for incoming
Central Office calls.
3. When night mode is set at the main node, satellite nodes not equipped with an ATTENDANT CONSOLE
[A-3] can automatically be set to the night mode by CENTRALIZED DAY/NIGHT MODE CHANGE -
CCIS [C-56] service.
4. A TAS indicator can be provided for each nodes incoming trunks.
5. An incoming call terminating in the Night mode will have the following order of priority:
a.) NIGHT CONNECTION - FLEXIBLE - CCIS [N-16],
b.) NIGHT CONNECTION - FIXED - CCIS [N-15],
c.) TAS [T-27]. Incoming calls will overflow to TAS [T-27], if this feature is provided, when the
NIGHT CONNECTION FIXED/FLEXIBLE [N-1] [N-2] [N-15] [N-16] stations are busy.
6. TAS indication will be activated for the LDN, WATS, FX, CCSA incoming calls.
7. TAS indication can be provided on a TENANT [T-12] basis.
8. Individual stations can be denied access to this feature via CLASS OF SERVICE - INDIVIDUAL [C-15].
9. If the system is changed to the day mode while a TAS call is being indicated, a call terminating at a node
without an ATTENDANT CONSOLE [A-3] will not be transferred through the CCIS network to an
ATTENDANT CONSOLE [A-3].
10. This feature is also referred to as Universal Night Answer (UNA).
11. The TAS indicator must be locally provided.
12. All ATTENDANT CONSOLES [A-3] assigned to handle calls for a particular group of stations (whether
or not they belong to the same TENANT [T-12]) must have NIGHT CONNECTION [N-15, 16] set before
this feature will be activated.

Uniform Numbering Plan - CCIS U-5
U-5  Uniform Numbering Plan - CCIS
General Description
In a CCIS network, a Uniform Numbering Plan enables a user to call any other station in the network using a
Uniform Numbering system. Two alternative numbering plans are provided:
 In the first plan, the user dials a four or five-digit station number. The node in which the called station is 
located is identified by either the first digit or the first two digits of the station number. More than one lo-
cation number can be assigned to a particular node.
 In the second plan, the user dials a single-digit access code, a three-digit code identifying the particular node 
in the CCIS network, and a two, three, or four-digit station code.
Operating Procedure
To call a station at another office using Numbering Plan 1: 
1. Lift the handset; receive dial tone.
2. Dial the four or five-digit telephone number. 
3. The call is routed to another node according to programmed routing information, and the called station
rings. 
4. The called station answers and the parties are connected. 
To call a station at another office using Numbering Plan 2: 
1. Lift the handset; receive dial tone.
2. Dial access code + office code 
- station code:
X-XXX-XX, or
X-XXX-XXX, or 
X-XXX-XXXX 
3. The call is routed to the node designated by the Office Code. The called station rings. 
4. The called station answers, and the parties are connected.
Service Conditions
1. Numbering Plan 1: 
a.) All telephone numbers must be four or five digit numbers.
b.) The location of the PBX can be identified by either the first digit or the first two digits of the
telephone number.
2. Numbering Plan 2: 
a.) The calling and called party’s LCD can display the office and station codes or the station code
only. This option is selected via the Maintenance Administration Terminal (MAT).
b.) Within the same PBX, a station-to-station call is made by simply dialing the two, three, or four-
digit telephone number.
3. The maximum number of digits per telephone number is eight.

U-5 Uniform Numbering Plan - CCIS
Interactions
If seven-digit Uniform Numbering Plans are used, an access code to the CCIS network may be added. Thus, a total
of eight digits will be dialed. For example, a user in Illinois wishes to reach a CCIS station number (753-4526) in
New York. Two options exist for network setup. The digit 8 may be programmed as a CCIS network access code,
such as a Least Cost Routing access code. The user then dials 8-753-4526. With this option, the 8 is assigned as the
CCIS access code. Digits 8-753 and all other CCIS office codes must then be listed in the AFRS command. The
second option is to program 753 as the CCIS access code, as in an LCR access code. If 753 is assigned as the CCIS
access code, then 753 and all other CCIS office codes must be listed in the AFRS command. In this case, the user
only dials 753-4526.
