The S400M FXS module allows the TDM800P card or TDM2400P card to
terminate four analog telephones per module.
Because of the modular design, a user can activate additional ports at
any time with more S400M daughter cards. The S400M module passes all
the call features any standard analog telephone line will support.
Worldwide certifications are pending.
Note: To use the S400M module, you must provide 12V DC
power to the TDM800P card or TDM2400P card, either from the computer's
power supply or from the Analog FXS Module Power Supply.
