This is a Cisco 4-port FXS and DID voice/fax interface card. The FXS port is used to connect directly to phones, fax machines and key systems. The card generates battery polarity reversal and caller ID, and it also provides an off-premises DID connection from the central office. It also serves incoming calls from the PSTN.
