Off line ATM data transmission scheme

Background of demand

With the vigorous development of the national banking and financial industries, a large number of joint-stock banks, local banks, and foreign banks have emerged. In order to provide good services and compete for users, various banks have set up ATM machines in public places such as shopping malls and office buildings. However, how to connect these ATM machines with the banking system at a lower cost and with flexible installation methods has become a problem that must be solved.

Solution

There are generally two ways for data exchange between ATM machines and bank central networks: one is to connect the ATM machine to the bank central network through a wired private network; Another way is to achieve data exchange with the bank's central network through the public network via wireless means. This method has relatively low construction and maintenance costs, but requires wireless devices to support VPN functionality and achieve data encryption and protection.

The CPE-OB equipment of BOTT technology accesses the mobile Internet through 3G/4G wireless network, and establishes VPN connection with the VPN router of the bank center through NATT technology, so that the ATM machine can establish a virtual private network with the bank core network. At the same time, the Bote CPE-OB device supports IPSEC technology to ensure the communication security of ATM machines and prevent hacker attacks.

Program features

1.The terminal equipment adopts wireless access method, which makes construction simple and fast, and reduces construction costs.

2. Adopting wireless access with high mobility and no regional restrictions, ATM terminals can be installed in areas covered by wireless signals, making networking convenient and expanding the coverage of ATM terminals in the entire banking system, making it more accessible to the public.

3. The terminal transmission equipment automatically dials the number when powered on, and can also set the online time according to the actual situation, without the need for manual processing, suitable for situations where ATM machines are unmanned.

4. Support SNMP/TR-069 network management protocol, support operator private network, provide web-based system configuration interface and maintenance interface, support remote version upgrade and device management.

5. Support device fault self check and device self-healing function.

6. Support VPN secure tunneling function, including PPTP, L2TP, GRE, and IPSEC.

7. Wireless technology enables low system transmission power, low electromagnetic pollution to the environment, and low electromagnetic interference to other automation equipment.
