NOTE: When generating gerbers, DO NOT enable "Include frame (board size)".
      Only the /white outline/ on the "O" layer is the correct outer board edge.

    REV-E: MAY 2022
    ----------------
        More copper for LG on cable C. For longer wire runs this gives brighter lights
	and less dimming for line in use while other lines are flashing.

	Dropped C spares for 49 and 50 signals

	Added pin# labels to bottom silk

	Removed common AG (for 2830)

	NOTE: REV-E has electrical changes that make it incompatible with older
	      revisions, so don't interconnect REV-E boards with older boards.
	      REV-E boards must be at either end of RJ45 cables, including any
	      bridged runs.

	When I printed these board pairs, I made the pairs "snap away" based on
	the outline splitting the pair.  So when ordering, under "PCB Specifications",
	change "Different Design:" from "[1]" to "[2]". This effectively changes
	"Delivery Format" from "Single PCB" to "Panel by customer".

    REV-D1: APR 2022 (Not printed)
    ------------------------------
	Added MFR part#s

	Added dots for pin#1

    REV-D: FEB 2022 (Many printed)
    ------------------------------
        Added NT LOGIC jumper for buzzer

	Added velcro slots


    REV-C: AUG 2021
    ---------------
        Fixes NPTH issue in REV-B

	Slightly more info in the silk screen for the PHONE board, indicating wire colors
	as well as pin#s.

	Labels on the PHONE board rotated

	Some trace routing simplification, but no electrical changes.

	Added URLs to point to the board's revision specific website.
		   
    REV-B: OCT 2020
    ---------------
        The PHONE board uses an 8 port RJ-45 connector to allow bridging to other phone sets.
	This inherited the REV-A NPTH problem which was fixed in REV-C.

    REV-A1: SEP 2021 (no date on board)
    -----------------------------------
	Same as REV-A, but fixes the NPTH confusion. (Non-Plated Thru Hole)

    REV-A: OCT 2020 (no date on board)
    ----------------------------------
	A complete copy of the REV-A board made with ExpressPCB, just without the
	Seriss logo.

	This revision confuses PCBway because it's not clear if the holes are NPTH.
