What Is an FXS Port?
An FXS port supplies the analog telephone interface required by a conventional analog endpoint.
Within a VoIP gateway, the FXS interface converts between the analog endpoint and the IP-based voice network.
Total Access 924e for Analog Phones
The 24-FXS configuration can support large groups of compatible analog phones while allowing the external carrier service to migrate toward SIP or IP-based communications.
This can be valuable in organizations that want to retain existing analog handsets or telephone wiring.
Total Access 924e for Fax Machines
Compatible analog fax machines can connect through FXS ports on the Total Access 924e.
Successful fax operation over IP can depend on:
- T.38 support
- Carrier configuration
- Network quality
- Voice codec settings
- Gateway configuration
- Fax-device compatibility
Total Access 924e T.38 Fax
The Total Access 900e platform supports T.38 fax functionality for compatible deployments.
T.38 is designed to transport fax communications across IP networks more reliably than carrying fax entirely as ordinary voice audio.
Total Access 924e for Analog Modems
The Total Access 900e platform supports compatible analog modem applications.
Because modem traffic can be sensitive to codec and network conditions, application compatibility should be verified before migrating business-critical modem connections.
ADTRAN Total Access 924e with Lifeline FXO
Selected Total Access 924e configurations combine 24 FXS ports with a lifeline FXO interface.
This configuration allows the gateway to support high-density analog station connectivity while also providing an external analog telephone-line connection for supported backup or survivability applications.
