ATM Functions

Service is connection oriented, with data transferred over a VC

A cell-switched network (architecture).

Fixed-size cell (53-Bytes)

Uses Asynchronous time-division multiplexing (Asynchronous TDM).

Advantages

Revenue opportunities:

High performance via hardware switching.

Dynamic bandwidth for bursty traffic.

Disadvantages

Processing overhead as messages are segmented into cells

Segmentation mismatch, as the last cell in a fragmented message may not be fully used.

Pin Capturing

Personal Identification Number (“PIN”) capturing is a worldwide problem.

PIN capturing refers to a method of strategically attaching

ATM Commands

Command Description atm filter-expr

show atm filter-expr

Displays a specific ATM filter expression or a summary ATM filter expression.

show atm filter-set

Displays a specific ATM filter set or a summary ATM filter set.

atm accounting (interface)

ATM Networking

ATM Devices and the Network environment.

ATM is a cell-switching and multiplexing technology that combines.

The benefits of circuit switching (guaranteed capacity and constant.

ATM Errors

1. Notify the bank or ATM owner.

2.  Act quickly.

3. Link down.

4. Amount deduct from account but did not come out from atm machine.
