FXO or Foreign Exchange Office, is a telephone signaling interface that receives POTS, or "plain old

is a telephone interface which provides battery power, sends dial tone, and generates ringing voltage. A
standard telephone plugs into such an interface to receive telephone service. There are 4 channels on each
tributary card with each channel providing 64kbps voice bandwidth. The connectors are all RJ-45, which
also readily accept RJ-11 connectors as well.
