SunnyStar Co., Ltd

SunnyStar Co., Ltd Quad S400M Module

SKU CH-HSSM-8N93M

Adds four analog telephone ports to compatible TDM cards for POTS line termination

  • Terminates four analog lines per module
  • Modular design lets you add ports anytime
  • Compatible with TDM800P and TDM2400P cards
  • Supports all standard analog call features
  • Works with A800P and TDM2400P analog cards

Quad S400M FXS Module

The Quad S400M is an analog FXS daughter card designed for SunnyStar TDM series telephony cards. It provides four ports to connect standard analog telephones or fax machines directly to a compatible host card. Each module adds four terminations for plain old telephone service lines. The modular design lets administrators expand port capacity incrementally as requirements grow.

Who It Suits and Who It Does Not

This module suits installers deploying A800P, TDM800P, AEX8000P or TDM2400P cards who need additional analog station ports. It is not for systems that lack a compatible TDM host card or for installations requiring digital PRI or BRI interfaces. Buyers needing more than four ports per module should evaluate higher-density alternatives.

Four Ports Per Module Decides Fit

The single specification that decides fit is the four analog ports delivered by each S400M module. A host card accepts multiple modules up to its maximum slot count, so total port count scales in steps of four. Verify the host card model and available slots before ordering to match the required line capacity.

Questions about this item

Can I add this S400M module to my existing TDM800P card to get four more analog ports?

Yes, the S400M plugs into a TDM800P or TDM2400P card and adds four FXS ports for analog telephones.

How do I verify the module is operating correctly once installed?

The card will detect the new ports; you can then register analog handsets and confirm dial tone on each of the four lines.

Does the package include the TDM800P base card or only the daughter module?

Only the quad S400M daughter module is supplied; the TDM800P, TDM2400P, A800P or AEX8000P base card must be purchased separately.
