Quad FXS module for Asterisk systems

The SunnyStar S400M adds four analog station ports to compatible Sangoma analog cards, letting an Asterisk PBX ring and power up to four standard telephones or FXO-equipped devices per module.

Expands 800 or 2400 Series cards

Each S400M plugs into an 800 Series or 2400 Series analog card and replaces empty module slots with live FXS channels. The upgrade is worth it when you need more internal extensions than the base card provides.

Requires 12 V DC on the host card

To operate, the host TDM800P or TDM2400P card must receive 12 V DC from the computer power supply or the dedicated Analog FXS Module Power Supply. The module itself does not connect to the PSTN.

Questions about this item

Does the S400M module need a separate 12V DC power feed to the TDM800P or TDM2400P card?

Yes, the S400M requires 12V DC power supplied to the TDM800P or TDM2400P card, either from the computer power supply or the Analog FXS Module Power Supply.

How is the S400M FXS module installed on the analog card?

The S400M mounts onto an 800 Series or 2400 Series analog card; the step often missed is providing 12V DC power to that card before the module will function.

How many analog stations can one S400M module support before another module is needed?

Each S400M provides four FXS channels, so one module supports four analog stations; additional stations require extra S400M modules.
