## Summary description

The Yeastar S2 FXS Module provides two FXS ports for expanding compatible Yeastar PBX systems.

## Long description

The Yeastar S2 FXS Module provides two FXS ports to expand compatible Yeastar PBX systems, enabling connection of analog phones, fax machines, or other telephony endpoints to a VoIP/PBX platform. Designed for integration with Yeastar systems, the module offers straightforward analog line extension for small offices, branch sites, or environments where local analog devices must remain connected while leveraging central IP telephony management.
Advantages
The module adds two independent analog FXS interfaces without requiring an external gateway, supporting direct connection of devices that depend on traditional phone line signalling. Its compact design and compatibility with Yeastar PBX architecture simplify installation and reduce the need for additional hardware. The module helps maintain existing analog equipment investments while enabling centralized call routing, provisioning, and management through the host PBX.
Suitable for
 Small offices that need extra analog phone or fax connections
 Branch locations requiring local analog endpoints with central PBX control
 Environments where specific devices (fax machines, legacy phones, point-of-sale terminals) must remain on analog lines
 System upgrades where gradual migration from analog to IP telephony is planned
Key specifications
 Number of FXS ports: 2 analog ports for direct device connection
 Interface type: Standard FXS signaling compatible with analog telephony endpoints
 Form factor: Module designed for insertion into compatible Yeastar PBX chassis or expansion slot
 Compatibility: Works with supported Yeastar PBX models that accept modular expansions
 Power and control: Powered and managed through the host PBX system
How to use
Install the module into the designated expansion slot of a compatible Yeastar PBX following the host system’s installation procedure. After physical insertion and securing, connect analog phones, fax machines, or other devices to the FXS ports using standard telephone cables. Access the PBX web interface or management console to detect the new module, configure port settings such as caller ID, dial plan mapping, and any line-specific parameters, and assign extensions or routing rules to the connected analog endpoints.
Usage recommendations
Verify that your Yeastar PBX model supports the S2 module before installation and ensure firmware is up to date for full compatibility. Use short, high-quality telephone cables for reliable connections and configure device-specific options (fax passthrough or T.38 support via the host PBX if required) within the central management interface. When deploying in a multi-branch environment, document port assignments and routing rules to simplify future maintenance.
