What does a DSL network look like?
A17: The diagram below depicts several important possible configurations for an ADSL installation. Service to the home in this example is ADSL.lite and the twisted-pair wiring to/from the central office is carrying both voice and data. No POTS splitter at the customer premises is needed to separate the low frequency voice signals from the high frequency data signals. The telephone system in the home is not altered in any way and the computer connection is made to any existing phone jack. Inside the central office, a POTS splitter after the main distribution frame (MDF) sends the voice signal off to the voice switch while the data signals are aggregated by a DSL Access Multiplexer (DSLAM) and then sent via a switch or router off to the Internet Backbone.
