Digium's X100P and X101P have been replaced by the TDM410P product. The TDM410P range offers up to four FXO, FXS or a combination of both modules on a single card, and is a much higher quality card for use in your Asterisk system.

If you are shopping for an X100P or a clone, we recommend you consider either the Digium TDM401B, with one FXO port, or the Digium TDM411B, with one FXO port, and one FXS port for connecting an analog telephone. The TDM410P boards are much easier to configure, especially if you are new to Asterisk, and they offer some great features when compared to the X100P and its clones.
