Thanks for the bit terminological nit picking. This is a reference to the type of cards I used with Asterisk and Plain Old Telephone Service lines.
http://www.digium.com/index.php?menu=product_detail&category=hardware&product=TDM400P The Wildcard TDM400P is a half-length PCI 2.2-compliant card that supports FXS and FXO station interfaces for connecting analog telephones and analog POTS lines through a PC. Using Digium's Asterisk Open Source PBX software and standard PC hardware, one can create a SOHO (Small Office Home Office) telephony environment that includes all the sophisticated features of a high-end business telephone system.
