Quad FXO module for analog cards

The SunnyStar X400M is a quad FXO interface module designed for TDM2400P, TDM800 and AEX800 full-length PCI cards. It adds four analog telephone line ports to a compatible host card. The module enables termination of standard POTS lines for VoIP applications. It is a new component supplied in red colour.

Suits expandable telephony builds

This module fits integrators who need to add four FXO ports to an existing supported PCI card. The modular design allows further port activation later with additional S400M or X400M daughter cards. Builders requiring different port types or incompatible host cards should consider other interface modules. It does not function as a standalone device.

Integrates with supported PCI cards

The X400M installs directly onto a TDM2400P, TDM800 or AEX800 card to provide the analog line interfaces. Each module handles four FXO connections and passes standard analog call features. Adding modules frees up expansion slots by consolidating multiple lines onto a single host card. Compatibility is limited to the specified card models.

Questions about this item

Which host card must I already own for the X400M module to work?

The X400M plugs into a TDM2400P, TDM800 or AEX800 full-length PCI card, so one of those must be installed first.

Will the X400M operate alongside older analog cards such as the 800 or 2400 series?

Yes, the module is designed for the 800 and 2400 series cards, letting you add four FXO ports to those existing boards.

How can I verify the X400M is passing calls correctly after installation?

Connect up to four POTS lines to the module ports; each active line should show standard analog call features such as dial tone, ringing and caller ID.
