Authorization Code - Tie Line Incoming Routes A-29
A-29  Authorization Code - Tie Line Incoming Routes
General Description
This service feature offers an outside party the ability to enter an AUTHORIZATION CODE [A- 20] through an
incoming TIE Line trunk.
Operating Procedure
When the incoming route is restricted or when an AUTHORIZATION CODE [A-20] is always required:
1. The called number, office code, and terminal number are received by the TIE Line trunk.
2. The outside calling party hears a special dial tone.
3. Dial the AUTHORIZATION CODE [A-20].
a.) The connection is established when the AUTHORIZATION CODE [A-20] is valid.
b.) Busy tone is sent to the calling party when the AUTHORIZATION CODE [A-20] is invalid.
Service Conditions
1. The outside calling party must be able to generate DTMF signals to the NEAX2400 IMX when entering
AUTHORIZATION CODE [A-20].
2. An AUTHORIZATION CODE [A-20] can be used for incoming calls to a uniform station or for LEAST-
COST ROUTING [L-5] tandem connections.
3. CALL WAITING - TERMINATING [C-12] is available when the called station is busy, after the
AUTHORIZATION CODE [A-20] is entered and validated.
4. INTER-OFFICE OFF-HOOK QUEUING [I-11] is available if the called route is busy, after the
AUTHORIZATION CODE is entered and validated.
5. Through programming, the system defines the AUTHORIZATION CODE [A-20] to be required for all
TIE Line incoming calls or when a restriction is encountered. This is assigned on a per-tenant basis.
Note:
There are two methods of AUTHORIZATION CODE assignment - Full Implementation and the Checksum. In the Full
Implementation method, the whole AUTHORIZATION CODE is assigned in the AATC command, and System Data 1,
Indexes 12, 13,& 14 are assigned 00H. In the Checksum method, partial assignment for each AUTHORIZATION
CODE is assigned in the AATC command. The last one or two digits (programmable option) are determined by the
system according to the data assignments in ASYD, System Data 1, Indexes 12, 13, & 14.
Interactions
1. If FORCED ACCOUNT CODES [F-7] are used, AUTHORIZATION CODES-TIE LINE INCOMING
ROUTES are not allowed within the same tenant.
2. AUTHORIZATION CODES-TIE LINE INCOMING ROUTES may be used in conjunction with
ACCOUNT CODES [A-18].
3. When assigning an AUTHORIZATION CODE Restriction of 1 in AATC, the RSC must be constructed
in ARSC.
4. AUTHORIZATION CODEs can be unrestricted or assigned one of 15 Route Restriction Classes (RSC 1
to 15).
5. There are no restrictions regarding the first digit of AUTHORIZATION CODEs, except what is
programmed in AMND. Tenant 0 does not conflict with the PBX numbering plan.
Note:
The access code to the feature AUTHORIZATION CODE - TIE LINE INCOMING ROUTES must be assigned within
the PBX numbering plan.

Interactions (cont’d)
6. If ASPA, SRV: LCR (Least Cost Route Selection) / LCRS (Register Sender LCR) AH parameter is
assigned as data “1”, the request for an AUTHORIZATION CODE is determined by the ARSC
assignment of the station in relationship to the route chosen. For AUTHORIZATION CODE - TIE LINE
INCOMING ROUTES, no RSC is assigned against the incoming TIE Line, therefore,
AUTHORIZATION CODEs are always required. Trunk connection will be determined against the RSC
of the dialed code.
7. When a D
term user initiates the LAST NUMBER CALLED - Dterm [L-6D] feature, the
AUTHORIZATION CODE will be recorded if previously dialed.
8. The AMND command determines the length of AUTHORIZATION CODEs based on the first digit of the
code.
9. AUTHORIZATION CODEs are recorded by STATION MESSAGE DETAIL RECORDING [S-10].
10. AUTHORIZATION CODEs cannot be entered by the Attendant Console.
11. PEG COUNTS [P-7] of invalid AUTHORIZATION CODEs are not available.
12. AUTHORIZATION CODEs can be dialed by a user, when establishing a CONSULTATION HOLD [C-
17] connection.
13. For Procedure 2, LCR(S) must be provided.
14. For senderized TIE Lines, see UNIVERSAL SENDER [U-3]. Also, the ANND command must be
programmed for senderized TIE Lines. If other services, such as, STATION MESSAGE DETAIL
RECORDING [S-10] and LEAST-COST ROUTING [L-5], the AMND command will be programmed.
If digit translation is required, go to the ASTP and AOSP command.
15. MISCELLANEOUS TRUNK RESTRICTION [M-3]. Restrictions to TIE trunks are determined by the
Route Service Class (RSC) assigned to the AUTHORIZATION CODE.
Programming
STEP 1:ASYD - System Data 1, Index 4, Bit 4 = 1: Temporary Class Conversion is required. 
System Data 1, Index 12. If Index 12 = 0, no Checksum method is used, and Indexes 13 and 14 are
ignored, regardless of their assignments. Each Bit in Index 12 directly correlates to a digit in the
AUTHORIZATION CODE assigned in AATC, and will determine the first digit of the Checksum
method. For this example, 26428 has been assigned as the AUTHORIZATION CODE in AATC. Pick
any Bits, 0 - 4, and flag those Bits as data 1.
Note:
Bit 0 - 7 may be used when 8-digit AUTHORIZATION CODES are assigned in the AATC command
.
System Data 1, Index 13. Each Bit in Index 13 directly correlates to a digit in the AUTHORIZATION
CODE assigned in AATC, and will determine the second digit of the Checksum method. Pick any Bits
0 - 4, but not the same combination of Bits as picked in Index 12.

Programming (cont’d)
ASYD - System Data 1, Index 14 determines the algorithm used to calculate the last two digits of
every AUTHORIZATION CODE. (Only decimal numbers may be used in this index, therefore,
hexadecimal values A to F may not be assigned). 
System Data 1, Index 14 = X & Y, where X and Y represent any arbitrarily chosen decimal digit 1- 9,
and where Y is used to determine the first digit, and X is used to determine the second digit in the
Checksum method. The following data, 37H, has been used for the example calculation:
Note:
If only one digit is to be added via the Checksum method, then System Data 1, Index 13 data will be 00H and Index
14, digit X (Bits 4 - 7) = 0.
Example Calculation:
In AATC, 26428 has been assigned. In System Data 1, Index 12, Bits 0 and 3 were chosen; 26428
2 + 2 = 4. 
The decimal value of Bits 0 - 3 of Index 14 = 7. 
4 + N =7. N = 3
. 
7 is obtained as any whole number greater than 4 that ends with a 7, the decimal value as determined in
System Data 1, Index 14, Bits 0 to 3. In AATC, 26428 has been assigned. In System Data 1, Index 13,
Bits 4 and 1 were chosen; 26428
8 + 6 = 14. 
The decimal value of Index 14, Bits 4 - 7, is 3. 
14 + N = 23. N = 9
. 
23 is obtained as any whole number greater than 14 that ends with a 3, the decimal value determined in
System Data 1, Index 14, Bits 4 - 7. The AUTHORIZATION CODE will be 26428-39
.
Note:
Digits 39, determined by the Checksum method, will be unique to the AUTHORIZATION CODE 26428. 26428 will not
be followed by any digits other than 39.
ASYD - System Data 1, Index 43, Bit 2, is service set tone sent after AUTHORIZATION CODE
ASPA access code? 0/1: No/Yes. Assign data “1”. System Data 1, Index 93, Bit 6. Are the AMND
tables Separate or Common for tenants in the system? 0/1: Separate/Common. Assign data “0” for
separate tables. 
System Data 2, Index 3, Bit 4: Is Account Code used with AUTHORIZATION CODE? 0/1: No/Yes. 
System Data 2, Index 3, Bit 5: Type of code: 0/1 AUTHORIZATION CODE/ Forced Account Code;
assign data “0”.
STEP 2:ANPD - Reserve a number level for feature access. Assign for Normal (N), Hooking (H), and Busy
(B) (if applicable to any feature in this level). Assign NND in accordance with a predetermined
numbering plan.

Programming (cont’d)
STEP 3:ASPA - For SRV = SSC (Service Code) SID = 42, assign the access code. For the NND parameter, no
assignment is required when AUTHORIZATION CODE [A-20] operates by itself. When Account
Code [A-18] operates with AUTHORIZATION CODE - TIE LINE INCOMING ROUTES, assign for
SRV = SSC (Service Code), SID = 42. The NND value will include the number of digits in the
AUTHORIZATION CODE access code, and Account Code. 
Note:
Procedure 1 is not available with AUTHORIZATION CODE - TIE LINE INCOMING ROUTES. For example:
45   -  26428    - 623423       - 9-1-617-555-2323
(ACC) (AUTH CODE) (ACCOUNT CODE) (DESTINATION CODE)
ASPA ACC = 45 NND = 8 (ACC+ACCOUNT CODE)
For SRV = LCR (Least Cost Route Selection) / LCRS (Register Sender LCR), if operating Procedure 2 is used, (dialing
the AUTHORIZATION CODE after the number dialed), assign data “1” to the AH parameter when programming the
LCR(S) access code. Therefore, operating Procedure 2 is only available with LEAST-COST ROUTING - 3/6 DIGIT
[L-5].
STEP 4:ASFC - For stations allowed AUTHORIZATION CODE - TIE LINE INCOMING ROUTES, assign a
Class of Service that allows SFI 27.
STEP 5:AMND - For Tenant 0, assign the Destination Code (DC) as the first digit of all AUTHORIZATION
CODEs and the Maximum Necessary Digits (MND) of the AUTHORIZATION CODE. For the above
example, a DC of 2 is assigned with an MND of 7. The MND value will include the digits added by the
Checksum method.
STEP 6:AATC - Assign the TN, Digit Code (DC) (the actual code itself), the AUTHORIZATION CODE
Restriction (ACR) as data “1”, and Service Feature Class (SFC) and Route Restriction Class (RSC). If
ACR is assigned as data 2, Allowed: RSC and SFC parameters are not programmed. (SFC parameters
are not operational.)
STEP 7:LATC - List all the AUTHORIZATION CODES. This is the simplest way to determine what digits
have been added to the system with the Checksum method. This is not required if the Checksum
method is not used. 
TIE Line Programming
STEP 8:ARTD - Assign the TIE Line routes as shown below: 
RT:1
1-OSGS :2 2-ONSG :3  5-TF :1 6-TCL :1 7 L/T :1
8-RLP :2 15-LSG :1
STEP 9:AT R K - Assign the LEN, TIE Line Route Number, Trunk Number, and Tenant Number. 
STEP 10:MBTK - Assign the Make Idle status to the TIE Line Trunks.
STEP 11:ANPD- Assign a number level for trunk access. Assign Connection Index, CI = N, H; Normal (N) and
Hooking (H). Number of Necessary Digits is usually 1 or 2. Busy Lamp Field is not activated. 
STEP 12:ASPA - Assign the access code as assigned in ANPD. Type of Service, SRV = OGC (Outgoing Call)
Outgoing Trunk. Assign the route number associated with this access code. 
STEP 13:ARSC - The Route Restriction Class (RSC) must be constructed to allow the station access to the
involved routes.

FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node. 
(Note)
STEP 1:ANPDL - Reserve a number level for feature access. Assign for normal (N), Hooking (H), and Busy
(B) (if applicable to any feature in this level). Assign NND in accordance with a predetermined
numbering plan.
STEP 2:ASPAL - For SRV = SSC (Service Code) SID = 42, assign the access code. For the NND parameter,
no assignment is required when AUTHORIZATION CODE [A-20] operates by itself. When Account
Code [A-18] operates with AUTHORIZATION CODE - TIE LINE INCOMING ROUTES, assign for
SRV = SSC (Service Code), SID = 42. The NND value will include the number of digits in the
AUTHORIZATION CODE access code, and Account Code. 
Note:
Procedure 1 is not available with AUTHORIZATION CODE - TIE LINE INCOMING ROUTES.
For SRV = LCR (Least Cost Route Selection) / LCRS (Register Sender LCR), if operating Procedure 2
is used, (dialing the AUTHORIZATION CODE after the number dialed), assign data “1” to the AH
parameter when programming the LCR(S) access code. Therefore, operating Procedure 2 is only
available with LEAST-COST ROUTING - 3/6 DIGIT [L-5].
STEP 3:LATCL - List all the AUTHORIZATION CODES. This is the simplest way to determine what digits
have been added to the system with the Checksum method. This is not required if the Checksum
method is not used.
TIE Line Programming
STEP 4:ARTDN - Assign the TIE Line routes as shown below: 
RT:1
1-OSGS :2 2-ONSG :3  5-TF :1 6-TCL :1 7 L/T :1
8-RLP :2 15-LSG :1
STEP 5:ANPDL - Assign a number level for trunk access. Assign Connection Index, CI = N, H; Normal (N)
and Hooking (H). Number of Necessary Digits is usually 1 or 2. Busy Lamp Field is not activated.
STEP 6:ARSCN - The Route Restriction Class (RSC) must be constructed to allow the station access to the
involved routes.
Note:
When using ASYDL or ASYDN to program an FCCS feature, the basic programming of ASYD is required in addition
to ASYDL or ASYDN.

A-30 Automatic/Manual Intercom
A-30 Automatic/Manual Intercom
General Description
This feature permits multiple Dterm users to simultaneously call all the stations in a preassigned group, regardless of
their idle/busy status. An INTERCOM member can optionally override another INTERCOM station in a two-party
INTERCOM connection. This service is referred to as INTERCOM BRIDGE. INTERCOM service is separated into
two types, AUTOMATIC INTERCOM (AICM) and MANUAL INTERCOM (MICM).
Automatic Intercom
All stations in the INTERCOM group are alerted simultaneously with a lamp indication. Ringing is directed to one
predefined station, as in a button and buzzer INTERCOM arrangement.
Manual Intercom
All stations in the INTERCOM group are called simultaneously with a lamp indication. The calling INTERCOM
station manually sends a one-second tone to the called INTERCOM signal station, as in a button and buzzer
INTERCOM arrangement.
Operating Procedure
 AUTOMATIC INTERCOM
To initiate an Automatic INTERCOM call: 
1. The INTERCOM station presses the AICM key and goes off-hook (within 5 - 10 seconds). 
2. The INTERCOM station will hear ringback tone. A specified station rings. 
3. One of the called INTERCOM group stations answers the call and is connected to the calling station.
To answer an Automatic INTERCOM call: 
1. The AICM key will flash, indicating an incoming INTERCOM call. The called station will also ring
according to the preassigned system parameters. 
2. If the called station is already engaged in a conversation with a non-INTERCOM call, the station may
press the AICM key after pressing the HOLD key. Ringing will stop.
To bridge into an Automatic INTERCOM call: 
1. When two stations are engaged in an INTERCOM call, a third station in the same INTERCOM group
presses the AICM key and goes off-hook. 
2. A three-party conference is established. The called stations may hear a Warning Tone when the station
bridges into the call. This Warning Tone is pre-assigned in System Data.
 MANUAL INTERCOM
To originate a Manual INTERCOM call: 
1. A station presses the MICM key and goes off-hook (within 5 seconds).
2. The station will hear ringback tone. 
3. The calling station sends a chime to the INTERCOM station by pressing the SIG key.
4. When one of the called INTERCOM stations answers the call, the calling station will be connected. Also,
all stations in the group share the common talk path and can pick up an unanswered INTERCOM call. 
To answer a Manual INTERCOM call: 
1. The MICM key will flash, indicating an incoming INTERCOM call. The called station may also hear one
second of ringing from the calling INTERCOM station. 
2. If the called station in the INTERCOM group is already engaged in a conversation with a non-
INTERCOM call, the station may press the MICM key after pressing the HOLD key.

Automatic/Manual Intercom A-30
Operating Procedure (cont’d)
To bridge into a Manual INTERCOM call: 
1. When two stations are engaged in an INTERCOM call, a third station, belonging to the same INTERCOM
group, will press the MICM key and go off-hook. 
2. A three-party conference is established. The called stations may hear a Warning Tone when the station
bridges into the call. This Warning Tone is preassigned in System Data.
Use of the SIG key:
1. The Manual INTERCOM Signal (SIG) key is operational at all times. An INTERCOM call is not required.
If the signaled station is ringing from another call, the Manual INTERCOM signal will interrupt that
ringing.
 PRIME LINE PICK UP - D
term [P-13D]
The Dterm may be programmed to seize the incoming call on the AUTOMATIC, MANUAL, or DIAL
INTERCOM [D-87] lines before the Prime Line. If two incoming calls terminate simultaneously to the
Prime Line and the MICM line, when the user goes off-hook, PRIME LINE PICK UP-D
term [P-13D] will
seize the MICM line before the Prime Line. If only the Prime Line is ringing when the user goes off-hook,
PRIME LINE PICK UP-D
term [P-13D] will seize the Prime Line.
Service Conditions
1. Only Dterms can be assigned as a member of an INTERCOM group.
2. All members of the same INTERCOM group must be assigned in the same Module Group (MG).
3. Up to 16 stations may be assigned to one INTERCOM group. Each station in the INTERCOM group can
be assigned as both a Manual and Automatic INTERCOM member of two different groups.
4. No more than one connection can be established at the same time in one INTERCOM group.
5. A three-party conference can be established in an INTERCOM group if INTERCOM Bridge service is
available. If a fourth party tries to activate INTERCOM Bridge service, the connection will be denied.
6. The maximum number of INTERCOM groups (Automatic or Manual) in a NEAX2400 IMX PBX is 50
per MG.
7. It is possible to assign one group of stations as an AICM group, Dial INTERCOM group, and an MICM
group at the same time.
8. The DISTINCTIVE RINGING [D-10] sent from an incoming AICM station takes priority over the ringing
of multi-line appearances.
9. Service features normally available to multi-line appearances are not available for INTERCOM lines.
10. INTERCOM lines cannot be held with the activation of the HOLD key.
11. When MANUAL SIGNALING [M-47] is performed by a user, this ringing (one second) takes priority
over any other incoming call indications from the multi-line appearance.
12. When a station is moved from one INTERCOM group to another INTERCOM group, through system
commands, the AICM or MICM key on the associated D
term must be cancelled before the change is made.
13. Port traffic and station PEG COUNT [P-7] reports will not record the use of the INTERCOM feature.
14. Dedicated feature keys on the D
term cannot be used while on an INTERCOM call. Only the SPEAKER
key can be used for hands-free operation.
15. FCCS link is not available for this feature.

A-30 Automatic/Manual Intercom
Interactions
1. The RECALL key will not operate on an INTERCOM call.
2. THREE-WAY CALLING [T-6] must first be provided.
3. The AICD Command must be assigned before the AKYD command.
4. When assigning the PRI parameter in AKYD, the following data selections are available.
5. No programming is required to enable the SIG key to remain active at all times.
6. The SIG key, when pressed by a calling station, will interrupt other ringing signals at the called station.
7. Hands-Free operation is available with AUTOMATIC/MANUAL INTERCOM. When an incoming call
terminates to a station, by pressing the SPEAKER key, the line seized is based on the PRI assignment of
the AKYD command.
8. MANUAL SIGNALING [M-47] will not operate if the DATA key has been pressed.

A-52 Account Code - Attendant
A-52 Account Code - Attendant
General Description
This feature provides the ATTENDANT CONSOLE [A-3] with the capability to enter an Account Code into the
system after talking with a CO outgoing/incoming call.
Operating Procedure
The Attendant talks with the CO trunk call.
1. Press the START key.
2. Dial the Account Code feature access code. Service set tone is heard.
3. Dial the Account Code (up to 10 digits).
4. Dial the desired telephone number.
Service Conditions
1. The Account Code may be a maximum of 10 digits.
2. When the Account Code is entered again for the same call and station, the last code entered will be
recorded on SMDR [S-10, 47].
3. Account Code dialing is available for an ATTENDANT CONSOLE [A-3] connected to a trunk.
4. The feature access code for Account Code will be a maximum of 3 digits.
5. An Attendant can enter an Account Code of fewer digits than the maximum length defined, indicating the
end of entry by the pound “#” key.
Programming
STEP 1:ASYD - System Data 1, Index 43, bit #2. Is service set tone sent after the ASPA access code for
ACCOUNT CODE? 0/1: No/Yes. Assign data “1”. 
System Data 2, Index 3, bit 4. Is ACCOUNT CODE used with Authorization Code? 0/1: No/Yes. 
System Data 1, Index 93, bit #6 = 0.
STEP 2:ANPD - Reserve a number level for service feature access. Assign Connection Index, CI = N, H, B;
Normal, Hooking, and Busy (applicable to any service feature assigned to this level). Assign NND in
accordance with a predetermined numbering plan.
STEP 3:ASPA - For SRV = SSC (Service Code), SID = 41, assign the access code. Assign the number of digits
in the ASPA service feature access code plus the number of digits that will appear in the ACCOUNT
CODE for the NND parameter. When ACCOUNT CODE operates with AUTHORIZATION CODE
[A-20], the above assignment is omitted. In ASPA, assign for SRV = SSC (Service Code), SID = 42.
The NND value will include the number of digits in the ASPA service feature access code plus the
number of digits that appear in the ACCOUNT CODE.
For example:
45 - 511234 - 617- 555 - 2323
2    +    6    =      8
ACC   +   ACCT CODE   =    NND
For example:
44 - 623423 - 511234 - 617 - 555 - 2323
2     +     0     +     6     =      8
ACC     +     AUTH CODE     +     ACCT CODE     =     NND
