55..55 E3 Setup and StatusE3 Setup and Status
E3
represents the 34.368 Mbit/s PDH layer. The Ports SetupPorts Setup screen gives you
access to the PDH layer setup for the transmitter and/or receiver of the
currently selected port.
E3 allows transmission of data streams that are nominally running at the same rate,
however allowing for some variation in the speed around a nominal rate (+/-125 ppm
variation around 34.368 Mbit/s).
E3 frame defined by ITU-T G.751 has 1536 bits during the period of 22.375 kHz. 12
bits are assigned to the overhead, and 4 bits parity are available as an option.
