It is used to process the On-Us(both acquiring bank, issuing bank are same)/ OFF-Us(acquiring bank, issuing bank are different) based on the configurations defined by Issuing bank.

It can process VISA, MasterCard and Amex etc., cards(debit/credit) as per their standards.

Basically it is based on ISO 8583 protocol. It can process both magnetic stripe and ICC(Integrated Chip Card) transactions as well.

All the data has been transfered in encrypted/protocol based format.

Institutions that need to share the data, should have public, private cryptographic keys distributed between them.

All Card, PIN(Personal Identification Number) releted secured data are processed by Host Security Module.

Off-Us Transactions that has been initiated by VISA,Mastercard based Cards, are routed to respective card associations, then they will route it to the respective Issuing banks.

ATM Switch also take care of dailt clearing, settlement processing as well.

It drives the ATM mostly based on 91x/NDC+ procol formats.

Screens, next states, time out based actions and all controlled by thr switch itself.

1 What devices are used in an ATM network?

An ATM network is made up of an ATM switch and ATM endpoints. An ATM switch is responsible for cell transit through an ATM network. The job of an ATM switch is well defined: it accepts the incoming cell from an ATM endpoint or another ATM switch. It then reads and updates the cell-header information and quickly switches the cell to an output interface toward its destination. An ATM endpoint (or end system) contains an ATM network interface adapter. Examples of ATM endpoints are workstations, routers, digital service units (DSUs), LAN switches, and video coder-decoders (CODECs). Figure 20-3 illustrates an ATM network made up of ATM switches and ATM endpoints. from Muhammad Faraz Ahmedfaraz_vu@hotmai.com

2 What are ATM interfaces and discuss their types?

ATM is a dedicated connection switching technology that organizes the digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology. Some of the ATM interfaces described below. ATM Interfaces: An ATM network consists of a set of ATM switches interconnected by point-to-point ATM links or interfaces. ATM switches support two primary types of interfaces: UNI and NNI. UNI (User Network Interface) It connects ATM end systems (such as hosts and routers) or user equipment and ATM equipment for example a workstation and the ATM switch. Depending on whether the switch is owned and located at the customer’s premises or is publicly owned and operated by the telephone company, UNI can be further subdivided into public and private UNI. Public UNI: A public UNI connects an ATM endpoint or private switch to a public switch. Private UNI: A private UNI connects an ATM endpoint and a private ATM switch. NNI (Network to Node Interface) This Interface is a connection between ATM devices. Private NNI (P-NNI): A private NNI connects two ATM switches within the same private organization. Public NNI or Inter Switching System Interface (ISSI): A public NNI connects two ATM switches within the same public organization. ICI (Inter-Carrier Interface) The interface between different ATM carriers. Broadband Inter-Carrier Interface (B-ICI) DXI (Data Exchange Interface) It is the interface from ATM into legacy equipment such as routers into ATM using HDLC. Between routers and ATM Digital Service Units (DSU)


What is the function of hec in the ATM header format?

I think this is about networking not banking. ATM stands for Asyncrhonous Transfer Mode and HEC stands for Header Error Control.


How switch function differs from user defined functions in C?

. please give me 3 or 4 differences.one difference is that user defined can be called anytime but not for switch There is no such thing as 'switch function'
