Figure 3.5 shows an example of organization of a four-pair operation mode. Four xDSL
channels are combined into one group of xDSL channels, though which a E1 stream and
Ethernet packets are transmitted. The use of this scheme involving the FlexDSL Orion2
equipment allows one to increase the transmission range, compared to the use of only one xDSl
channel (the adavantage in the transmission range will depend on the cable parameters and
noise immunity).
