ISO IEC 17982:2012 pdfダウンロード。Information technology — Telecommunications and information exchange between systems — Close Capacitive Coupling Communication Physical Layer (CCCC PHY)
1 Scope
This International Standard specifies the CCCC PHY for Full duplex and Broadcast communication in time slots on frequency division multiplex channels.
2 Conformance
Conforming entities implement:
both Talker and Listener,
listen before talk (LBT) for both Talker and Listener,
the capability to execute association on FDC2 and to communicate on (FDC0 and FDC1), (FDC3 and FDC4), or (FDC0, FDC1, FDC3 and FDC4),
the capability for Talkers and Listeners to use any of the 8 TDS on a FDC,
both Full duplex and Broadcast communication, and pass the tests in Annex A as specified herein.

5 Conventions and notations
5.1 Representation of numbers
The following conventions and notations apply in this document.
– A sequence of characters of ‘A’, ‘B’, ‘C”, ‘D, ‘E’ or ‘F’ and decimal digits in parentheses represent numbers in hexadecimal notation unless followed by a ‘b’ character see next.
– Numbers in binary notation and bit patterns are represented by a sequence of 0 and 1 digits or ‘X’ characters in parentheses followed by a ‘b’ character, e.g. (0X11X010)b. Where X indicates that the setting of a bit is not specified, and the leftmost bit is the most significant bit unless the sequence is a bit pattern.
5.2 Names
The names of basic elements, e.g. specific fields, are written with a capital initial letter.
6 General
The protocol architecture of CCCC follows ISO/IEC 7498-1 as the basic model. CCCC devices communicate through mediators, such as conductive and dielectric materials.
Plate-electrodes for CCCC device E and F are equivalent to the reference plate-electrode assembly.
