Generic ATM Framework

1. Assumptions
It is assumed that the reader of this document is familiar with the navigation around T24 product and is
familiar with the T24 Accounting concepts, FT, AC.LOCKED.EVENTS Modules.

This document provides information about the Functional workflow, templates/versions/enquires used
and ISO Message standards supported in ATM Interface.

2. Functionality Overview
ISO 8583 is a standard for creating and reading financial transaction messages including Point of Sale
(POS) transactions, Automated Teller Machines (ATM) and network-to-network, real-time financial
transactions. These messages enable consumers to withdraw money from ATM's and conduct
business in a real-time world.
The ATM Interface is developed as a middle layer between the ATM SWITCH and T24. The interface
consists of a plug-in for Application Server to receive the messages via a dedicated port and translate
the ISO messages. Application Server sends the ISO message to T24 where the ISO message
converted to OFS message format based on the mapping files to be updated on to T24 applications.
After the transaction has been completed at T24, the response ISO messages are formatted within the
scope of the ATM Interface. The response messages are indicated with the appropriate error or ok
status depending upon the T24 applications reply status.
The protocol used for communication between the host and the switch is usually TCP/IP via sockets.
ATM interface provide a high performance multi-threaded synchronous socket listener that has custom
functionality/intelligence built-in for handling ISO messages with length prefix through TCP/IP.
Application Server can be configured for listening ISO messages on any number of ports as required
by the load on the site. However, a judicious choice should be made considering the load so that not
to leave too many ports listening idle. The switch should try to throw open multiple
sockets/connections on the same port(s) when the load increases.
The main features of this interface is to caters all the standard ATM operations like Cash withdrawal,
Point of Sale, Balance enquiry, Mini statement, Statement request, Account transfer, Cash Deposit
and Cheque Book Request.
Note: ATM Interface supports ISO 8583:87 and ISO 8583:93 versions only. All Functionality specified
below is supported for both ISO 8583:87/93 versions.

ATM FRAMEWORK

How is it working?
When a customer uses an ATM terminal connected to the switch server, the switch sends a message
to T24. Depending upon the message and various functions, accounting entries are generated in T24
and responded either with an error message or requested details back to the ATM Interface. These
transactions could be done from any ATM and depending on where and which customer is doing the
transaction we could broadly classify them as:


ON US TRANSACTIONS – T24 customer doing transaction in an ATM attached to T24
branch



NETWORK TRANSACTIONS - T24 customer doing transaction in an ATM attached to nonT24 / other institution’s branches



LORO TRANSACTIONS - Non-T24 customers doing transaction in ATM attached to T24
branch.

Once the interface is started, the parameters required for the Interface are read from the mapping
tables. Java Listener listens to a port where ATM Switch will be sending the ISO8583 messages.
Once the raw ISO8583 message is read from the port, ATM Interface converts this raw ISO message
into OFS message format and sends it to T24, for the execution of corresponding transaction. After
the transaction has been completed at T24, the response messages are formatted in ISO8583 format
and sent back to ATM Switch.

Purpose


All online transactions will be approved or rejected by T24.



The time-out will be agreed between Gpack and the switch on a case to case basis
considering the prevailing network and other conditions.

 STAN, DATE.TIME will be used as unique identifier for each message by T24 unless
otherwise specified.

4.1 NETWORK MESSAGES
Network transactions are used as handshake between ATM switch and T24 host system. The Network
messages will be initiated using a 0800 request with network-management-information-code (Sign on
– ‘001’, Signoff – ‘002’, Echo Test - '301') from ATM switch and the T24 host will respond with an
0810.

4.2 BALANCE ENQUIRY
When a customer does the balance enquiry at ATM terminal, the request message will be sent to T24
Host. T24 will check the corresponding account and then get the balance details by launching an
enquiry. The charge amount will be collected from the customer account if applicable.

GPACK
11

Generic ATM Framework

4.3 CASH WITHDRAWAL
When any customer does a cash Withdrawal in ATM, machine will raise a debit to the cardholder’s
account/Bank Account and a corresponding credit to the ATM cash account. If T24 is on-line,
withdrawals are only allowed if sufficient funds are available.
The below workflow describes the applications and accounting levels entries raised during On-Us,
Remote On-Us, Off-Us transactions

Note: Same Workflow happens when T24 goes Off-line and advice messages are posted.

4.4 MINI STATEMENT
When a customer does the mini statement transaction at ATM terminal, the request message will
be sent to Host. T24 will check the corresponding account and then get the last 10 transaction
details for that account by launching an enquiry.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions.

4.5 STATEMENT REQUEST*
When a customer does the statement request transaction at ATM terminal, the request message will
be sent to Host. T24 will check the corresponding account and then updates a local table in T24 with
the account number and the statement requested date.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions.

GPACK

4.6 PURCHASE TRANSACTIONS
There are two methods of POS transactions processed into T24.


BASEI & BASEII[Force Posts]*



STANDARD TRANSACTION

Note: Any one method only can be implemented for POS Transactions [Bank & Switch has to
decide on this]
Base I:
When a customer purchases goods from any POS terminal the transaction message will be sent to
T24 Host, ATM interface will lock the amount in the customer’s account based on the lock period
mentioned in Parameter table.
The below workflow describes the applications and accounting levels entries raised during
Authorization request based transactions.

Base II & Standard Transactions:
When a customer purchases goods from any POS terminal the transaction message will be sent to
T24 Host, ATM interface will validate the transaction terminal, account, amount and will raise an
accounting entry in T24.
Difference between Base II and standard transactions is Base II will be sent as Advice message
whereas other case will be sent as On-line message
The below workflow describes the applications and accounting levels entries raised during On-line
& Base II based transactions.

GPACK

Generic ATM Framework

4.7 INTRABANK TRANSACTIONS
When a customer does account to account transfer (within bank) via the Atm terminal the transaction
message will be sent to Host, T24 will validate the debit and credit account, available balance in Debit
account and based on the validation check, T24 will post the transaction and send the response to the
switch with the processing status.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions

Note: Same Workflow happens when T24 goes Off-line and advice messages are posted.

4.8 CASH DEPOSIT*
When a customer does cash deposit in the ATM terminal, the transaction messages will be sent to
T24 host to raise an accounting entry. T24 will validate the account and credit the amount to the
customer’s account and debit the ATM GL account.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions

Note: Same Workflow happens when T24 goes Off-line and advice messages are posted.

4.9 UTILITY BILL PAYMENT*
A Customer can go into an ATM and pay his bills. T24 will debit the cardholder’s account and a
corresponding credit to the ATM cash account. If T24 is on-line, Bill payments are only allowed if
sufficient funds are available.
The below workflow describes the applications and accounting levels entries raised during On-Us,
Remote On-Us transactions

Note: Same Workflow happens when T24 goes Off-line and advice messages are posted.

CHEQUE DEPOSIT*

When a customer does Cheque deposit in the ATM terminal, the transaction messages will be sent to
T24 host to raise an accounting entry. T24 will validate the account and credit the amount to the
customer’s account and debit the ATM GL account.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions

Note: Same Workflow happens when T24 goes Off-line and advice messages are posted.

4.11

CHEQUE BOOK REQUEST*

When a customer requests for the Cheque book at ATM terminal, the request message will be sent to
Host. T24 will check the corresponding account and create a new request in CHEQUE.ISSUE table
with status as Requested.
The below workflow describes the applications and accounting levels entries raised during On-Us
transactions.

GPACK
17

Generic ATM Framework

4.12

FULL REVERSALS

When a customer does any reversal of financial transactions in any ATM terminal/POS, switch will
send the request message to T24 for processing. Switch will wait response message from T24.
In case of any network issues/T24 host down the response for request message will not reach the
switch. In such a case switch will send the reversal message to T24 host to reverse the original
transaction. T24 will get the original transaction reference based on the original data sent by switch
and reverse the accounting entries in T24
Reversal will be done immediately whenever the reversal request received by T24.

4.13

PARTIAL REVERSALS

When a customer does any partial reversal of financial transactions in any ATM terminal/POS,
switch will send the request message to T24 for processing.
In case of FUNDS TRANSFER, we validate if original transaction is already stored in T24. If so,
we will credit customer account based on the replacement amount sent.
In case of AC.LOCKED.EVENTS, we validate if original transaction is already stored in T24. If so,
we will release the amount locked and then lock the amount sent in replacement amount field.
Reversal will be done immediately whenever the reversal request received by T24.

4.14

PAYMENT VIA TELLER*

Customer can directly walk to Teller and pay Bill payments. The AT.ISO.GEN.MSG routine attached
to the version passes the data to Third party via jar file placed. If a successful response is received
from third party vendor, then the payment is completed. TT or FT can be raised based on this process.

TABLE 2 – INTRF.MAPPING

DETAILED FIELD DESCRIPTION:

FIGURE 5. PRE.RTN IN INTRF.MAPPING
This is a multivalve set. Customized hook routines can be attached here, which will trigger during the
request phase or response phase based on the Message Type set. Routine should have one
argument value passed inside in case of attaching routine at the response mapping record e.g.
ATM.ISO.ERR.COD.RTN (ISO.MESSAGE).
Sample Scenario:

In Balance Enquiry Request message, above routine formats the balance to be sent in Field
54. Client can attach a new format routine based on his requirement and change the balance format
sent to Field 54. Balance format routine should have two incoming argument and one outgoing
GPACK
25

Generic ATM Framework

argument which contains the balance formatted data as per the client requirement. This routine will be
triggered from No file enquiry routine for balance formation.
Sample Routine is provided below:

In Case of Mini statement Request message, above routine formats the mini statement to be
sent in field 48. Client can attach a new format routine based on his requirement and change the Mini
statement format sent to Field 48. Mini statement format routine should have three incoming argument
and one outgoing argument which contains the mini stamen detail with formatted data as per the client
requirement. This routine will be triggered from No file enquiry routine for mini statement formation.
Sample Routine is provided below:

Note: For Separate/Multiple charges transaction entries, we are using generic routine
AT.POST.CHG.TXN.RTN for raising entries and AT.REV.CHG.TXN.RTN [for reversal mapping
records alone] for reversing entries. These routines have to be attached in PRE.RTN of corresponding
Response Mapping Records. These routines will be triggered based on the parameterization done in
ATM.CHG.TABLE and ATM.SPLIT.CHG.TABLE.
GO BACK

FIGURE 6. FIELD.SRC.VALUE IN INTRF.MAPPING
GPACK
26

Generic ATM Framework

If FIELD.SOURCE is set as RTN, then Routine must be attached in FIELD.SRC.VALUE. The outcome
value of the routine will be assigned to its respective GLO.FLD.NAME value. Routine must have two
arguments passed inside e.g. AT.ISO.CALC.CR.ACCT (INCOMING, OUTGOING).
Sample Scenario:
For Inter Bank Funds transfer, we need Debit and Credit Acct no’s for raising FT Entry.
Below snapshot provides an idea about configuring values for Debit and Credit Account numbers.

If a value from incoming ISO Message is to be passed directly into DEBIT.ACCT.NO, then Intrf Fld Ps
can be set to its respective incoming position (102) and its Field Source can be set as INT.

If a value has to be fetched based on incoming ISO Message positions, then those values can be
placed in Intrf Fld Ps like this: 32*C%*49*C%*103.
32,49 and103 – Represents the incoming ISO Message position
C – Represents the specifying the constant value in the part of incoming value. Generally used to
include the Delimiter value”%” between different value position.
% - it’s the constant value which is used as delimiter.
Field Source should be set as RTN.
Field Src Value should have the Routine name.
Sample Scenario:
If ISO position 32, 49 and 103 has below values
nd

32 – 123456, 49 – 840, 103 – 43268.
The incoming variable (first argument) will hold the value as “123456%840%43268”. Second argument
will hold the actual account number for the particular T24 OFS field (defined in the Glo Fld Name)
Sample Routine is provided as below:

GPACK
27

Generic ATM Framework

GO BACK
Note: If separate charges are going to be configured in framework, AT.GET.BAL.AFT.TXN has to be
attached in FieldSrc Value and Field Source should be set as RTN for all response mapping records.
If this routine is attached, then account balance after charges will be reflected in the balance field.

6. Transaction Message Format
6.1 Base24/ISO Transaction Message
6.1.1 Message Header
A 4-byte ASCII or 2-byte message header containing the length of the message has to be sent at the
beginning of the message. The message length would exclude the length of the header.
Example:
Four Byte Header:
If the ISO message is 323 bytes, “0323” has to be added in front of the message. Therefore, the actual
data sent is 327 bytes.
Two Byte Header:
If the ISO message is 323 bytes, these bytes “ SOH C” [printed char format] has to be added in front of
the message. Therefore, the actual data sent is 325 bytes
Note: Configuration of 2 byte or 4 byte has to be done at Application Server level.

6.1.2

Bitmap Message Format

A system that communicates with ATM Interface must construct messages according to ISO 8583
standards. Messages constructed as such have three main Components:
 Message type identifier
 Primary & Secondary bitmaps
 Series of data elements

Message Type Indicator

Bit Map

Data Elements

6.1.2.1 Message type identifier
The message type identifier is a 4-digit numeric field with the following sub-fields:
First 2 digits are the Message class
Last 2 digits are the Message function
An example of a message type identifier for a financial request transaction sent to the ATM Interface is:
'0200'.

6.1.2.2 Bitmaps
Primary Bitmap
Format b-64
Length 16 bytes
Description
The primary bitmap is required in all messages. It determines which data elements are present. The
bits are interpreted from left to right where a 1 indicates the field in that bit position is present and a 0
indicates the absence of that field.

Secondary Bitmap
Format b-64
Length 16 bytes
Description
The secondary bitmap is present only if data elements 65-128 are present in the message. The
secondary bitmap has the same description as the primary bitmap.
Note: For T24 ATM Interface Primary & secondary bitmaps are mandatory.
