Typical lines are unshielded twisted pair cables. Any standard Ethernet cable is also usable.
Beside the RJ45 connector X107 SHDSL.EVB.4CH provides the possibility to use the pin
header X105 (SHDSL line #1), X106 (SHDSL line #2), X108 (SHDSL line #3) and X109
(SHDSL line #4) spaced 2.54 millimeters (0.1 in). Table 2 gives the pin definition.

The pin header X105 (SHDSL line #1), X106 (SHDSL line #2), X108 (SHDSL line #3) and
X109 (SHDSL line #4) are not mounted by default. It is possible to mount it on both PCB sides
to get an easy test adapter for evaluation or to use the SHDSL.EVB.4CH as a module.
Figure 6 shows the schematic of the SHDSL hybrid with line transformer L101, L102, L103
and L104 and SHDSL data pump V101 (PEF 24628 E).
Components and layout are influencing the SHDSL performance. Teleconnect can assist you
with the selection of additional line protection at raw ambient conditions.
