Electronic Data Interchange Implementation Guide

Section IV: Technical Environment

Each trading partner needs three general resources to interchange data electronically: computer hardware, software, and communication capabilities.

To transmit data between trading partners, certain hardware and software components must be in place. These products serve to convert standard text data into an X12 structure, arrange data into sets which match the receiving system, and execute the action required to transmit data across the telecommunications network. A Value Added Network (VAN), which is discussed later, serves the function of a bulk mail holder, providing temporary storage while waiting for addressees to retrieve their data items.

The items listed below are the minimum resources needed to begin submitting and receiving data via EDI:

  • An EDI Mailbox from an established VAN provider or a HUD Secure FTP Directory, if not using a VAN. Contact the HUD EDI Help Desk if deciding to use the Secure FTP option.
  • Microcomputer system (32 Bit - 1 GHz processor)
    • Secure FTP Software (FIPS 140-2 compliant) if accessing the HUD network directly using SFTP
    • Minimum of 20MB hard disk storage capacity
    • Windows XP SP3 or above
    • Communications adapter
  • Modem
    • Modem Cable/Telephone Jack
    • Internet Access
    • RS232 cable for connecting modem to phone jack
  • Data mapping interface or mapping software;and
  • EDI translation software

This section of the Implementation Guide outlines each of these requirements and provides guidance for acquiring the appropriate resources to support the EDI efforts. More information on Section IV is available in PDF format.
