FXS modules provide ringing voltage and battery to telephones or handsets and require substantial amount of 12V DC power in order to operate properly. The PCI interface on motherbo ards cannot provide sufficient quantities of this voltage necessary to ring 4, 8 or 24 modules. As a solution, Digium analog cards are mounted with a 4-pin disk-drive or Molex connector on the base board. This connector must be supplied with an internal power connector from the system's power supply if FXS modules are in use. 1PWR2401BLF- One external power supply bundle for analog card station (FXS) modules 1PWR2402BLF- Two external power supply bundle for analog card station (FXS) modules Show more
