The following information summarizes the minimum hardware requirements for the Local Area
Network (LAN).
● Cabling: Category-5, 5e or 6 to each workstation or server
Note: Wireless LANs (WiFi/802.11) may be an alternative if carefully designed
and implemented.
● Switches: 100baseTX
Note: If Network Applications such as Voice over IP or Streaming Video are to be
implemented, proper Quality of Service must be configured on the switches to
ensure Bankway performance.
● Addressing: Subnet for each branch and at least one for the data center. Addresses
should be organized in a hierarchy for summarization. Private IP addresses in the
private ranges (10.x.x.x, 172.16.x.x through 172.31.x.x, 192.168.x.x) are
recommended.
The following information summarizes the minimum hardware requirements for the Wide Area
Network (WAN).
● Router: Each location requires a manageable router with an Ethernet interface to the
LAN, a serial interface to DSU/CSU (or integrated CSU/DSU) plus the appropriate
interface(s) to a backup link, if implemented.
Note: The appropriate Routing Protocol depends on topology of the network and
the available bandwidth of the network. In general, RIPv2 or OSPF is best.
Internet access requires a separate link. Best practice specifies a separate router
plus a firewall and Intrusion Detection System for security.
● CSU/DSU as specified by the common carrier. It may be integrated into router, or
may require an interface to PBX.
● Data Circuits: The Speed of data circuits depends on traffic volume. Traffic other
than Bankway transactions such as e-mail, internet access, voice or video must be
considered. The following guidelines address Bankway traffic only. It is important for
you to evaluate your peak transaction volumes and to discuss this issue with your
preferred carrier14 to establish line speeds.
● Dedicated links: 256K minimum
