Many types of enterprises have a requirement for fax testing. Manufacturers of fax machines, fax modems, fax-related products and software companies, network equipment manufacturers, and network operators all have requirements for fax testing. These requirements include not only diagnostic testing for product development, but also requirements for production and QA testing, customer support testing, and (for network operators in particular) quality-of-service (QoS) measurements on a continuing basis. Typical customer types include the following:

• PC fax card manufacturers
• modem manufacturers
