DSL technologies ISDN Digital Subscriber Line IDSL uses Integrated Services Digital Network 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. ref cite press release url http www.cisco.com en US tech tk175 tk349 technologies q and a item09186a00800946d3.shtml title IDSL Frequently Asked Questions date February 26, 2008 publisher Cisco ref IDSL also avoids per call fees by being generally billed at a flat rate. IDSL is not available in all countries. ISDN digital subscriber line IDSL is a cross between ISDN and xDSL. It is like ISDN in that it uses a single wire pair to transmit full duplex data at 128 kbit s and at distances of up to RRD range. Like ISDN, IDSL uses a 2B1Q line code to enable transparent operation through the ISDN U interface. Finally, the user continues to use existing Customer premises equipment CPE ISDN BRI terminal adapters, bridges, and routers to make the CO connections. The big difference is from the carrier s point of view. Unlike ISDN, IDSL does not connect through the voice switch. A new piece of data communications equipment terminates the IDSL connection and shunts it off to a router or data switch. This is a key feature because the overloading of central ... no longer has access to ISDN signaling or voice services.
