Secure Transaction Gateway - dial Flashcards

1
Q

what is the STGd?

A
  • is a high density transaction processing gateway designed to run on industry standard, high performance 2U rack mount hardware.
  • is the next generation, market leading solution for carrier class transaction network service providers.
  • This specialized software suite can enable fast transaction processing of credit card authorizations, debit card fund transfers, health benefit authorizations, electronic benefits transfers, and other communications involving single-session transfer of small amounts of data.
  • designed to run on the industry-leading NewNet Total Control 1000 multiservice access platform
    => The transaction gateway also provides maximum reliability with redundant access router cards capable of switching from load balancing to automatic failover and back.

Q

Total Control 1000 Transaction Gateway Platform

A
  • Designed for future expansion with two Intel Sandy
Bridge processors onboard that support emerging technologies and applications with advanced high speed modem processing and DSP capabilities. This Secure Transaction Aggregation and Intelligent Routing & Switching System offers capability to support transactions from dial terminals to be completed rapidly and economically.
  • version 3.0d can be used for transaction processing over an IP network or over an X.25 network. The transaction gateway speeds transaction times with features such as Fast Connect, (reduces or eliminates steps such as alerting, audible ring, billing delay, answer tone, and call termination); and supports transaction protocols such as VISA I/II and Synchronous Data Link Control (speeds calls and reduces traffic to a processing host by up to 50%) with full protocol emulation.
  • uses DNIS number or transaction data fields like TPDU NII to route debit, credit, POS, healthcare, and EBT transactions to the host server over IP networks. The transaction processing system generates transaction specific Call Detail Records (CDRs) to Accounting server for transaction reporting, billing, monitoring etc. The system offers advanced IP routing for network traffic using network routing protocols (RIP, OSPF).

=> This system is compliant with PCI DSS standards for and provides secure remote access using Secure Shell (SSH).

Q

Is there a single point of Failure?

A

=> With multi span E1 or T1 DSP ports, plus support for redundant Access Router cards, the Total Control system is fully reliable. Load sharing is the default condition, but if a failure is detected in the card, the X.25 connection, or the IP connection, the system will automatically fail over to the second Transaction Gateway Access Router card and NIC.

Main Factors

A

*High Capacity in a Small Form Factor
Total Control STG provides high density modem span capability with up to 8E1/ T1s and optionally expandable to 16E1/T1s per 2U Server form factor and can be stacked for up to thousands of DS0s.

*Clustered Architecture
Multiple STG systems can be deployed in a clustered architecture with load distributed across these systems along with high availability and redundancy. All the deployed systems can be managed from one location by a single web based management GUI. This provides for easy scalability – scaling up is simply a matter of adding new systems.

  • Asynchronous and Synchronous Calls
    Total Control STG supports both Synchronous and Asynchronous calls on the same system.
  • VISA Protocol
    Enhanced support for the most current VISA standard makes the Total Control STG the perfect solution for legacy, point-of-sale, and host applications.
    TPDU Routing
  • Total Control STGd supports Transport Protocol Data Unit (TPDU) routing, providing the ability to complete transactions with greater efficiency and flexibility.
