[mrtg] Re: conversions for MaxBytes (fixed)

[Rippe, Mark (CCI-Warwick)]

oops.
the first line has a typo. (it's monday)
there is only one framing bit

	the t1 proto goes;
	1 framing bit					1 bit		=
1 bit
	8 bits times 24 channels		192 bits		=
193 bits
	1 framing bit			1 bit		1 bit	=	194
bits
	8 bits times 24 channels		192 bits		=
386 bits
	1 framing bit			1 bit		1 bit	=	387
bits
	8 bits times 24 channels		192 bits		=
579 bits
	1 framing bit			1 bit		1 bit	=	580
bits
	8 bits times 24 channels		192 bits		=
772 bits
	1 framing bit			1 bit		1 bit	=
773.bits
	8 bits times 24 channels		192 bits		=
965 bits
	1 framing bit			1 bit		1 bit	=	966
bits
	8 bits times 24 channels		192 bits		=
1158 bits
	1 framing bit			1 bit		1 bit	=	1159
bits
	8 bits times 24 channels		192 bits		=
1351 bits
	1 framing bit			1 bit		1 bit	=	1352
bits
	8 bits times 24 channels		192 bits		=
1544 bits
