An analog telephone adapter (ATA) converts an analog telephone port (Foreign exchange station, FXS) to a VoIP network.
A Centrex TVA interfaces centrex telephones and analog-based Centrex telephones.
Some telecom manufacturers have produced hybrid exchanges with TVA-like elements that support IP telephones and also have units or cards that allow connection of digital telephones.
Whether a standalone TVA or a hybrid PBX is deployed, the intention is to preserve investment in an installed base of telephones, and eliminate the need to install Ethernet network infrastructure.[1][2]
