DS1/J1
represents the 1.544 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.
DS1/J1 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 1.544 Mbit/s).
The DS1/J1 frame has one frame-bit and 24 channels during 125 μs. A channel
contains eight bits, so one DS1/J1 frame has 193 bits. The bits of channel 0 is used
for multi frame.
