RightFax Support Tip: Loop Current Errors

July 21, 2017 By Fax Girl Leave a Comment

Support DashboardOur RightFax support team here at The Fax Guys supports more than 800 RightFax servers nationwide. Over the years, we have learned a thing or two about solving numerous fax server issues, and we are always looking to share this knowledge with users whenever we can.

This month, our lessons are focusing on how to resolve loop current errors in RightFax.

Loop Current Errors: The Basics

Loop current is the electrical energy that flows through a telephone line. The current changes when a telephone headset is picked up or when a fax machine try to signal a line in order to transmit a fax.

Loop current in fax is when the fax board solution tries to signal the communication channel it needs to communicate to the gateway or network segment it is directly connected to. This is where errors can occur, and RightFax can report on what is happening when there is a failed transmission.

Errors That Can Occur

Fax admins can occasionally see errors in the FaxUtil interface or fax history. They will also be reported in Windows application logs, stemming from either the RightFax Boardserver module service. They are most likely to come from the RightFax DocTransport module service.

Whether you are using analog or T1/E1 or FOIP telephony, there are a few loop current errors that you can encounter:

  • Loop current not detected: the fax board solution could not detect a loop current before dialing the fax number.
  • Loop current detected: this can either be a fax board solution configuration error or an error that occurs when RightFax attempts to go off-hook to send a fax but finds that the phone is already off the hook. Essentially, two devices are trying to use the phone line at the same time.
  • Loop current failed: the fax board solution found that the line has current, but there is no valid value for the loop current.
  • Loop current dropped: the loop current dropped off during transmission.

Getting Started With Troubleshooting

Typically, you want to start at the fax board solution’s configuration to ensure that everything is working properly. From there, you move out toward the telephony network, starting with your local network and moving on to your network/telco service provider, carrier network and beyond from there.
