6 FXO-FXS Support

The Acme Packet 1100 supports using Foreign Exchange Office-Foreign Exchange Subscriber (FXO-FXS) interfaces in the U.S. to connect analog devices, such as fax machines, to a VoIP network. The FXO-FXS interfaces provide a way for you to direct traffic to a specific analog endpoint by creating a unique profile per channel. FXO-FXS support requires the optional transcoding Digital Signaling Processor (DSP) for reliable fax transmission with transcoding.
