N3Net is a hosted, adaptive and secure payment network service operated and managed by GHL Systems that provides nationwide coverage. Its communications backbone provides two levels of long distance communication redundancy for high reliability usage. It is also fully EMV-compliant and supports multi-protocols and multiple types of payment applications. Most importantly, N3Net provides high reliability, availability and security where encryption and authentication is built-in to ensure that data traffic is transmitted safely without any security risks.

Ultimately, a much lower cost of ownership is assured for our customers with just a single robust, quick and flexible connection from financial institutions to GHL Systems.

With N3Net, banks, financial institutions and businesses are provided with ultra-fast and reliable data access for their EDC terminals, computing and communication devices.

Additionally, N3NET utilizes a 128-bit key 3DES (Triple DES) encryption algorithm to encrypt information and data traveling within the backbone - for added security. N3NET is also monitored on a 24x7 basis to ensure peak network performance and business continuity.

N3net also provides the capability for multiple companies or financial institutions to perform inter-business transactions with each other without having to install additional infrastructure between them. With the same connectivity to N3net, financial institutions can communicate with one another; perform transactions as well as connect to their most valued customers (for transaction acquiring) directly.

In a nutshell, The N3net provides financial institutions, companies and banks a reliable nationwide network for transactions and data routing.

POSSIBLE SCENARIOS

N3NET MITIGATION

  
 

Hardware Failure

Complete Hardware Failure

Each of the 13 nodes is equipped with dual NetAccess hardware, ensuring that the site is protected against hardware failure.

 

Power Supply Failure

Each NetAccess network appliance is equipped with Dual-fully redundant power supplies that guard against power supply unit (PSU) failure. If one PSU is faulty, the other PSU will take over and provide the power to the hardware without interruption. 

  
 

Communication Line (Downlink) Failure

Line Robustness

All incoming lines are set up as hunting lines, if any one of the lines is made unusable by physical or electrical damage or operational/maintenance activities, the calls from EDC terminals will be re-routed to the next available line.

  
 

Communication Line (Uplink) Failure

Uplink Redundancy

All uplink from each node to the central location is connected via a GHL Systems backbone network.

 

If and when the uplink is down (i.e. the node is separated from N3Net), each NetAccess will immediately initiate a ISDN backup dial-up to the HQ or the nearest node.

 

This ISDN backup dial will re-establish the network connection.

 

Uplink Recovery

Once the main connection is established or is deemed reliable, NetAccess will switch over from the ISDN dial-up, back to the main connection. At this point, the ISDN dial-up line will end its connection.

  
 

Bank/FI/Company Connection Failure:

Client Connection Redundancy

All banks, financial institutions and companies are connected to N3net using TCP/IP. The routers used in this connection will have a primary lease line to provide the main connection from the N3net HQ to the client and a secondary ISDN line on the router to provide a backup connectivity.

 

If ever the main lease line is deemed unusable or down, the router will initiate the ISDN to the client’s end router (located in the client’s premise) and re-establishing the TCP/IP connection. This will minimize any down time caused by connection failure.

 

Client Connection Recovery

Once the lease line connection is made available again or is deemed to be reliable for use, the router will terminate the ISDN call and then switch over to the lease line carrier for the TCP/IP connection.
