Value Added Networks Guides (The Parker Hannifin Vendor Guidelines)
Before information can be transmitted using EDI, data from the sender/user must first be translated into a standard format, and then communicated using the standard format to a receiver. This communication process takes place through either point-to-point connection or through a third-party communications service. Point-to-point connection is only practical in businesses that do not deal with multiple trading partners. Third-party communication networks or Value Added Networks (VANS) eliminate the need for extra hardware, software, telephone connections, or manpower. Most trading partners find it convenient to use third-party networks. VANs are service bureau companies offering mailbox functions to trading partners, allowing them to receive and transmit their electronic transactions to multiple locations with minimal problems. For instance, General Electric Information Services (GEIS) has a VAN called EDI*Express, which has a local access network to which a person can subscribe and receive a mailbox. Parker directly subscribes to several VANs, and all of these third-party service providers interconnect with virtually all other VANs.
Therefore, Parker requires the use of a third-party network (VAN) service to provide store-andforward capability and compliance checking (see page 6 for more information). A listing of Value Added Networks will be provided upon request.
