1. a) describes the rules of implementation of balanced single pair cabling as specified by [3] within a balanced 4-pair cabling system with a current carrying capacity of 0,75 A per conductor as specified in [2];
2. b) describes the use of [2] components and cabling to implement and configure in accordance with [4], [5] and [3];
3. c) describes links and components for generic single pair channels in accordance with [1]. Particular areas of interest are
   1. 1) remote powering in accordance with [6],
   2. 2) loop resistance and maximum current,
   3. 3) insertion loss,
   4. 4) return loss,
   5. 5) noise considerations,
   6. 6) frequency range requirements (low and high),
   7. 7) length calculation of the SCP link 4-pair-cable, and
   8. 8) number of channels;
4. d) describes the use of application-specific single pair channels in addition to [1], 6.6.4;
5. e) describes guidance on single pair remote powering applications when using 4-pair cabling with current carrying capacity specified by [2];
6. f) describes guidelines for planning, administration and installation.

NOTE This document compares requirements of existing 4-pair cabling classes and single-pair classes. The described approach can be adjusted to any number of pairs.
