G.SHDSL Cable
Description
A G.SHDSL cable connects a G.SHDSL interface to a DSLAM directly to provide broadband network access service for users. One G.SHDSL interface can connect to four telephone lines through a G.SHDSL cable.
Structure and Pin Assignments
Figure 8-45 shows the structure of a G.SHDSL cable.
Table 8-70 lists the pin assignments of a G.SHDSL cable.

As shown in Table 8-70, a G.SHDSL cable uses the standard pin assignments. It has four ports, each of which has two wires (A/B). The two wires in a port can be assigned in any sequence, but the wire pairs must be assigned in certain sequence.
Connection
A G.SHDSL cable is connected as follows:
- The RJ45 connector is connected to the G.SHDSL interface of a router.
- The RJ11 connectors are connected to network devices, usually DSLAMs.
Ordering Information
Table 8-71 provides the G.SHDSL cable ordering information.
