Host Site RAS Server

Host Site RAS Server for Dial-UP Termination of ATMs & POS Terminals
The Gateway 1000 provides tremendous cost savings with the capability to convert Legacy ATMs and POS devices to IP for transport over any type of IP Network.

IP Connectivity Solution
If you're a financial institution with many POS terminals you might want to consider building your own dial-up network. Competition among the carriers is on the increase and the cost of dial-up PRI/T1 lines is decreasing rapidly. Carriers are now offering unlimited local and long distance services for a low fixed rate per month. This golden opportunity can drastically reduce your operating expenses quickly.
Traditionally, financial institutions use a transaction carrier in order to connect an ATM or POS device from a retail location to the host site. The dial-up circuits that the transaction company uses could cost as much as $40-$70 per line plus the transaction cost of $0.03 to $0.30 per transaction. These charges can add up quite fast, especially if the terminal is a high volume terminal. Usually when a terminal has very high volumes it will be moved to a leased line, which could cost $150 or more.
Sixnet Electronics can now help financial institutions reduce their high carrier cost with our RAS server solution. The Gateway 1000 was developed for banks, retailers, and EFTs who needed to build their own dial-up networks. With the Sixnet solution you can terminate up to 96 dial-up circuits over four T1s on one Gateway 1000.
The Gateway 1000 is extremely flexible with several different models to choose from. Also, the Gateway 1000 has many optional expansion cards that can be used depending on how many ports are needed and what type of interfaces are needed.
Today, manufacturers of host platforms and transaction switching systems are moving to IP based platforms. This presents a major problem for end-users whose terminals aren't compliant with TCP/IP standards. This is why the Gateway 1000's powerful Linux based platform also provides protocol conversion.
Sixnet Electronics is the industry leader in protocol conversion and we pride ourselves on our engineers' extensive knowledge of legacy protocols. Converting from Visa or other dial-up Async protocols to TCP/IP is made easy with the Gateway 1000. This capability allows our customers to migrate their entire network to TCP/IP without having to upgrade their terminals.
Also, the Gateway 1000 provides increased visibility into your dial-up network. Our network management and monitoring capabilities allow you to identify problem terminals immediately. The Gateway 1000 can also provide Terse Logging. In addition to the standard call records, new log files can be generated to provide a one-line summary of each call. This summary includes Caller ID, DNIS, Connect Speed, Call duration, and number of transactions. This data can be collected daily, weekly, or whenever appropriate and imported into an Excel spreadsheet for analysis.
Our advanced DNIS routing feature offers our customers the ability to route transactions to specific IP address based on the DNIS or number dialed. In addition, the Gateway 1000 can optimize different numbers dialing in for faster connection times based on various modem modulation types. One number can be optimized for 56k while another for low speed modems. All these options can be dynamically updated with no interruption in service.

Operation
Installation of the Sixnet Gateway 1000 is a simple process.
Install the Gateway 1000 at your host site. Have your carrier provide you with T1 service for your dial-up lines. Assign one phone number as a hunt group for your T1 or across multiple T1's. Then program your ATM's or POS devices with that phone number. The ATM or POS device will then dial in to the carriers switch; the carrier switch will then route the calls to your T1. The call will then be terminated in the Gateway 1000. The Gateway 1000 will then convert the Visa or other Async protocol to TCP/IP. Then the Gateway 1000 routes the transaction to the host or transaction switching system over IP.

The transaction process is as follows:
  1. The ATM or POS device dials a specific phone number when it has a transaction to process.
  2. The carrier switches the call to your host site over a T1 line.
  3. The Gateway 1000 verifies the caller ID and negotiates the modem speed.
  4. Once the call is terminated the Gateway 1000 will convert the Visa protocol to TCP/IP.
  5. The transaction is then sent to the host or transaction switching system for processing.
  6. Once the transaction is completed the ATM or POS device disconnects the line.
  7. A call record is then generated by the Gateway 1000.
Sixnet's cost-effective solution helps to eliminate the need for a transaction carrier, decreases transaction times, offers increased visibility into the network, and gives IT managers the flexibility to interface into any type of network.

Gateway Products and Feature
Gateway 1000 - The G1000 is our flagship product used by major banks, EFTs, and ISOs. The G1000 is a flexible and scaleable host site product used for converting and terminating a large number of circuits. The G1000 can be used as a host site concentrator to convert from Legacy to IP or from IP to Legacy. Also the G1000 can be used as a RAS server for dial-up termination and conversion to IP.
The G1000 comes in several different models depending on how many slots are needed. These models can be configured as a stand-alone unit or rack-mountable. All of the models provide protocol and interface conversion for dissimilar networks in remote locations or at the central site. The G1000 provides a wide range of Legacy protocol support for LAN and WAN networks and supports the protocol and text manipulation for each device or user.

Optional Expansion Cards:
  • T1 RAS Card
  • 1 Port Sync/Async Card
  • Dual T1 RAS Card
  • 4 Port Sync/Async Card
  • A 10/100 MB Ethernet card
  • 4 Port Async Card
  • Token Ring card
  •  8 Port Async Card

Sixnet can provide custom modifications to the protocols supported by the Gateway. We can provide text manipulation, custom data translations, unique network address mapping or specialized host application messages. These custom modifications can eliminate the requirement for changes in host application programs or network topologies; therefore, allowing you quick installation and ability to run production applications immediately.
Protocol Support - All of the Sixnet Gateway products support protocol conversion, and when it comes to protocol conversion, Sixnet is the industry leader with over 50 different protocols in our software library. Protocol conversion is necessary when converting a host to IP or introducing a new Transaction Switching System. Our Gateway products provide our customers with a seamless and non-intrusive migration to IP. Below is a list of the most Common Protocols Converted to TCP/IP:
  • Bisync 3270
  • Uniscope
  • SNA/SDLC
  • Bisync 2780/3780
  • Poll Select TC500
  • Visa I & II
Backup Routing - Fallback IP routing can be used if a backup host is available. Also, if a dial backup line is provided then the dial backup feature can be implemented. If the primary path (IP Connection) becomes unavailable, an external modem can automatically be enabled. Once the primary path becomes available, the Gateway will switch the connection back to normal operation.

Security - ATMs and POS devices are open for attack by hackers and Sixnet realizes this, so we have added additional security by incorporating VPN capabilities with Firewall functionality into our products. We provide a Linux based hardware solution, which is a secure way of preventing hackers from retrieving critical transaction data. Our Gateway products support Network Address Translation (NAT), filtering, and 3DES encryption. Our Gateway products are easy to install; and in most cases, no reconfiguration of the ATM or POS device is required.
