China Bank and NCR

Phase in feature-rich, NCR ATMs while maintaining legacy protocol network

When China Bank in the Philippines decided to "move tellers to sellers" by upgrading to more efficient NCR Automatic Teller Machines (ATMs), they faced several problems:

  • China Bank likes the security and stability of its SDLC/SNA protocol network.
  • The desired, feature-rich, NCR ATMs communicate via IP protocol.
  • Simultaneously upgrading all current, SDLC-based, NCR ATMs to new, IP-based, NCR ATMs is not only disruptive, but cost prohibitive.
Project Goals
  • Maintain bank's legacy protocol network.
  • Enhance customers' experience with IP-based, NCR ATMs.
  • Accomplish smooth transition to IP-based NCR ATMs.

Their solution: Phase in IP-based, NCR ATMs using the Gcom® Protocol Appliance 2G (GPA 2G).

The GPA 2G transports only the payload data itself (not the SDLC/SNA protocol) by applying a delimiter to preserve the logical message boundaries needed to send payload data over a byte stream connection such as TCP. Gcom calls these delimiters encapsulations.

Even better, Gcom has an encapsulation specifically designed to handle NCR ATM payload data, so the Gcom solution required no custom programming.

Now China Bank replaces SDLC-based, NCR ATMs with IP-based, NCR ATMs on its own timetable with no disruption to bank processes or customers.
