S-60 Synchronous Data Switching - CCIS
S-60  Synchronous Data Switching - CCIS
General Description
This feature allows a synchronous data terminal connected to a Dterm/Data Adapter to call a synchronous data
terminal connected to a synchronous Dterm/Data Adapter through the CCIS network.
Operating Procedure
To originate a synchronous data call from a Dterm equipped with a Data Adapter:
1. Press the DATA key on the Dterm. The DATA lamp lights steadily and the LCD displays:
2. Dial the telephone number of the DTE.
3. The DATA lamp flashes. The LCD displays:
4. When the DTE answers, a communication path is established and the DATA lamp lights steadily.
To release from a data call:
1. Press the DATA key.
2. The LED of the DATA key is extinguished and the call is disconnected.
To receive a data call at a Dterm equipped with a Data Adapter:
1. When a data call is received, the DATA lamp flashes and the Dterm rings.
2. Press the DATA key to answer the call.
3. The DATA lamp lights steadily.
Note:
If the Data Adapter is set for AUTOMATIC ANSWER [D-18], no manual operation is required.
Service Conditions
1. SYNCHRONOUS DATA SWITCHING - CCIS supports transmission speeds of up to 56 Kbps.
2. A D
term or Data Module must be used.
3. A synchronous data terminal connected to a Data Module can originate a call by using CCITT X.21, or
V.24 bis procedures, or by DATA HOT LINE [D-86]. Synchronous Data Modules can also be placed at
both ends of a fixed (Nailed Down) connection.
4. The calling and called DTEs must be code and speed compatible.
5. Synchronous DTEs connected to NEAX2400 IMX Data Modules or Data Adapters receive their timing
signals from the NEAX2400 IMX.
Interactions
1. When assigned, the DATA feature key acts as the telephone number of the data station.
2. The telephone number of the data station will only appear on one D
term set.
3. The telephone number of the data station may be used as a DID number.

Interactions (cont’d)
4. For greater 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).
Programming
STEP 1:ASDT - Assign levels 4, 5, 6, & 7 of a PA-4DLC as a TEC = 13. Data level 4 corresponds to voice

S-73 Supervisory Call - CCIS
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.

Toll Restriction - 3/6-Digit - CCIS T-26
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.
Programming
STEP 1:ASYD - SYS1, Index 75. Should the following commands be developed for Day/Night? 0/1: No/Yes.
Bit 0 - Developed ARSC command for Day/Night?
Bit 3 - Develop ATDP command for Day/Night?

Programming (cont’d)
See DAY/NIGHT CLASS OF SERVICE [D-15].
SYS2, Index 1, bit 3. Does TOLL RESTRICTION apply to SPEED CALLING - STATION? 0/1: Yes/
No.
SYS2, Index 1, bits 4 & 5. If TOLL DENIAL is required assign these bits as data “00”. If TOLL
DIVERSION is required assign these bits as “01”.
SYS2, Index 1, bit 7. Does TOLL RESTRICTION apply to SPEED CALLING - SYSTEM? 0/1: Yes/
No.
STEP 2:ARSC - Assign Route Restriction Classes. When assigned to stations these classes will determine
whether or not a station will be allowed access to a specific route or specific dialing sequence. Assign
the following:
DAY/NIGHT:Day/Night Mode
D: Day Mode
N: Night Mode
TN: Tenant Number
RT: Route Number
RSC: Route Restriction Class
RRI: Route Restriction Index
0: IC Restriction via ATTENDANT CONSOLE [A-3] (DDD, etc.)
1: IC Restriction Direct Connection (DID, etc.)
2: OG Restriction via ATTENDANT CONSOLE [A-3] 
3: OG Restriction Direct Connection (DDD, etc.)
RES: Restriction Data
0: Connection is Restricted
1: Connection is Allowed
2: Connection is Toll Restricted
STEP 3:AMND - This command is used to tell the system the total number of digits to expect based upon the
first few DIGITS DIALED. 9 plus a local call will equal 8 digits, 9 plus 1 plus an Area Code call will
equal 12 digits. Assign the DIALED DIGITS information and the corresponding MAXIMUM
NECESSARY DIGITS (MND) data. Flag this data as a Toll call, (data 1), or a local call, (data 0).
Note:
The digits underlined are to be listed in the DC parameter. Overseas or Operator assisted calls should be listed with
an MND = 24. Special dialing sequences such as 911 with an MND = 4 should also be listed.
N = 2 - 9, P = 0 or 1, X = 0 - 9
STEP 4:AT D P - This command is used along with AARP. This command designates the digit codes that will
be allowed, denied, or toll restricted. These codes are designated by Route Restriction Class. The
Number of Necessary Digit data is used to specify where a 3 or 6-digit translation should begin. The
digits to be examined for 3- or 6-digit translation are listed in AARP. Assign the following:
DAY/NIGHT:Day/Night Mode
D: Day Mode
N: Night Mode
TDM/OG:Tandem Connection/Outgoing Connection
T: Tandem Connection
O: Outgoing Connection
ICRT: Incoming Route Number (Tandem Connection Only)
RSC: Restriction Class (0-15)
OGRT: Outgoing Route Number
