15.2 DSL and Cable Modem Applications
Figure 15-4 shows an application where multiple xDSL or cable modems are interfaced to a single
DS3131. Such an application would exist in a DSLAM. The DS3131 is used to terminate both the
payload of the xDSL/cable modem link as well as the overhead channels (like the links used for signaling
and provisioning). In this application, one of the ports on the DS3131 has been dedicated to an HSSI to
allow the concentrated packet traffic to be linked to another entity. The local bus (if enabled) can be used
to configure and monitor the xDSL/cable modems.
