Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. ISDN Digital
Subscriber Line (IDSL) uses ISDN-based technology to provide a data
communication channel across existing copper telephone lines at a rate
of 144 kbit/s, slightly higher than a bonded dual channel ISDN
connection at 128kbit/s. The digital transmission bypasses the telephone
company's central office equipment that handles analogue signals. IDSL
uses the ISDN grade loop without Basic Rate Interface in ISDN
transmission mode. The benefits of IDSL over ISDN are that IDSL provides
always-on connections and transmits data via a data network rather than
the carrier's voice network.
