Explanation

 * A:Protective sheath around all 4 pairs
 * P:The individual pairs have protective sheath

Online sources
http://www.siemon.com/us/standards/13-02_over.asp says FTP = ScTP according to TIA (now called F/UTP by the source). The same source says that it now calls S/FTP what it previously used to call "PiMF", "STP", or "SSTP".

Useless sources:

STP have only two lines TOTAL, according to
 * http://www.interfacebus.com/Engineering_Dictionary_7.html and
 * http://www.ex-designz.net/atm_glossary.asp

Total confusion at this source - according to which STP can be anything!:
 * Unshielded Twisted Pair Cable (UTP): {most common} has four twisted pairs {typically 100 Ohm +/- 15% impedance}.
 * Screened Twisted Pair (ScTP) also called (STP): has a single braided screen over all four pairs {typically 100 Ohm +/- 15% impedance}.
 * Foil Twisted Pair (FTP) also called (STP): has a single foil wrap over all four pairs {typically 100 Ohm impedance}.
 * Fully Shielded Twisted Pair (SSTP) also called (STP): each pair shielded and shield over all 4 pairs {typically 100 +/- 15% Ohms}.
 * (Obsolete) IBM STP Cable (STP-A): each pair foil shielded and braid over both (2) pairs; also called (STP) {typically 150 Ohms}
