Figure 3.6 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 S-Access
ETHERLINK_II equipment allows one to increase the transmission range, compared to
the use of only one xDSL channel (the advantage in the transmission range will depend
on the cable parameters and noise immunity).
