Common Fax Problems

Facsimile has been a major communications channel for nearly half a century. You’d think that sending pages from one fax machine to another would be a simple certainty by now – but it’s not. The implementation of the T.30 protocol, which the International Telecommunications Union uses to govern fax transmissions, has varied widely from one manufacturer to the next, and even from one model line of fax machines to the next. On top of this native compatibility problem, the switched circuit public telephone network that fax was intended for is being rapidly replaced by Voice over IP, which switches data packets over the Internet. The impairment compensations built into fax for the switched circuit network actually cause problems over the switched packet network.

The outcome of all this has been an unfortunate litany of:

  • Fax calls that don’t connect with answering terminals
  • Fax calls that terminate without transferring all the queued pages
  • Fax terminals that appear to send/receive all pages but turns on an error indicator
  • Receiving fax terminals that print flawed pages
  • Fax calls that seem to take an inordinate amount of time to complete

It commonly falls to an IT or Communications manager to ‘make fax work,’ and that means finding a tool or service that can discover and analyze fax transmission problems. QualityLogic has been deeply involved in the facsimile protocol and making industry-leading tools for over 30 years.

Case Study:

Medical Center Fax Over IP

When this major university medical center added a new electronic record system, its fax usage increased dramatically. Personnel saw a substantial increase in fax call trouble reports, in spite of replacing older multifunction peripherals. With fax terminal locations spread through multiple buildings across a citywide campus, the medical center needed a coordinated, informed approach to control this problem.
