The S-Access Etherlink_IV supports TC-PAM16/32 and the new TC-PAM4/8/64/128 line coding. Thesupport of these line codes ensures compatibility with existing SHDSL equipment that is alreadyinstalled, in order to protect customer investments, while at the same time providing an upgradepath to the newest DSL technologies.SHDSL.bis Extended allows symmetrical data and voice transmission at speeds up to 15.2Mbpsover a single pair of copper. In addition, the S-Access Etherlink_IV modem range also supports DSLchannel bonding for up to 4 copper pairs in order to achieve speeds to 60.8Mbps! S-AccessEtherlink_IV SHDSL.bis Extended modems can provide up to 4 complete E1 interfaces, whichsupport framed and unframed services (G.703/G.704). An integrated 2 or 4 port Ethernet layer 2managed switch with VLAN support (10/100BaseT) ensures connectivity to IP services.
