The ViA POTS Module is required for making connections over POTS/PSTN (Plain Old Telephone Service) Analog Telephone Lines. Simply plug the module into a free expansion slot on your Tieline codec and dial to connect and broadcast studio quality audio.
Phone lines are being removed or superseded in many regions and traditional copper (POTS/PSTN) lines are often replaced by a range of IP over fiber alternatives. Migrating to these services with POTS codecs may be successful if the service supports a traditional fax machine. In many situations bandwidth over these networks is too limited even if connections are possible.
