SunnyStar TDM400P VoIP PCI 2.2 Card

The SunnyStar TDM400P is a half-length PCI 2.2-compliant card that provides one FXS and three FXO ports for connecting analog telephones and POTS lines to a PC. It targets small-office or home-office builders who want to deploy an Asterisk, TrixBox or Elastix telephony platform using open-source software. The four-port design fits a single expansion slot and uses standard Dahdi or Zaptel drivers for immediate compatibility.

Sustained Load Behaviour

Under continuous call traffic the card handles analog signalling and voice channels through its onboard modules without requiring active cooling. Driver stability relies on the mature Dahdi/Zaptel stack used by Asterisk-based distributions, so long-duration sessions remain consistent with typical PBX workloads. No thermal throttling or firmware throttling mechanisms are documented for this hardware.

Pre-Installation Checks

Verify that your motherboard has an available half-length PCI 2.2 slot and that the chassis can accommodate a low-profile bracket. Confirm your chosen PBX distribution includes Dahdi or Zaptel kernel modules for the TDM400 series. Buyers who need more than four analog ports or digital trunk interfaces such as T1/E1 will need additional or different hardware.

Questions about this item

How much power does the TDM400P draw from the PCI 2.2 slot when running continuously?

The card is a half-length PCI 2.2-compliant device with no active cooling, so it draws only the minimal current the slot provides for its four analog modules.

What software and drivers must already be installed on the PC for the TDM400P to work?

You need a Linux-based PBX such as Asterisk, TrixBox or Elastix with DAHDI or Zaptel drivers loaded before inserting the card.

Will the TDM400P coexist with an older Digium analog card in the same server?

Yes, the TDM400P is fully compatible with all analog Digium cards and modules and uses the same DAHDI/Zaptel drivers without changes.
