from the Telco, the line should be connected to the bottom (A) jack.

HOT TIP!
TIA/EIA- 568- A T568A and T568B are electrically identical. However the Green and

need to be the same for most of the system wiring. We will use the T568A color codes

in the cable illustrations of this manual. See Appendix 3 for a summary of the

HOT TIP!
While this cable only has 2 twisted pairs, the pairing is the same as standard
EIA/TIA- 568- A T568A (T568B is electrically equivalent) and this can be used.
