	What is IDSL?
		IDSL uses the same technology as ISDN except that it routes the signals through different equipment at the phone company or Telco.
		IDSL can be expensive to set up, but may be worth it to businesses or individuals that require faster service without the option of DSL.
		IDSL does not have this limitation, allowing clients at further distances to have an "always on" connection.

	IDSL Testing
		IDSL circuit testing generally requires both LT and NT emulation modes when testing from the Central Office and from the Customer Premises directions.
		IDSL testing on the S/T interface is also supported through the availability of the S/T interface and the associated NT and TE emulation modes.
		The IDSL Module provides external reference clock inputs to enable the test set to synchronize to the network to eliminate clock slip between the source from the test set and the circuit under test, ensuring a valid BER test result.

		On average, connectivity with IDSL is twice the speed of a regular dial-up connection.
		Ifyou use the IDSL line to view video-on-demand or other memory and processor hungry functions, you may find your PC is too slow.
		This is to ensure thatafter the extensive and time consuming efforts in establishing your connection to the IDSL service, you as a customer will agree to keep it for the set amount of time.

	Configuring IDSL Cards
		IDSL is part of a broad range of Ascend MultiDSL offerings that let you implement DSL technologies immediately.
		Because each IDSL card has 32 ports, you need two DB37 connectors and two 50-pin telco connectors (each of which support up to 24 ports) to accommodate all the ports on the IDSL card.
		The third DB37 connector is designed to be attached to a second IDSL card, thus bringing a total of 48 ports from the DB37 connectors to the 50-pin telco connectors.

	What is IDSL? - a definition from Whatis.com
		- IDSL is a system in which digital data is transmitted at 128 Kbps on a regular copper telephone line (twisted pair) from a user to a destination using digital (rather than analog or voice) transmission, bypassing the telephone company's central office equipment that handles analog signals.
		IDSL is a technology developed by Ascend Communications (now part of Lucent Technologies).
		IDSL is only one possible technology in the Digital Subscriber Line approach (of which Asymmetric Digital Subscriber Line or Asymmetric Digital Subscriber Line is best known) and an expedient approach that allows use of existing ISDN card technology for data-only use.

	ISDN Digital Subscriber Line - Wikipedia, the free encyclopedia
		ISDN Digital Subscriber Line (IDSL) transmits data digitally (rather than analog) on a regular twisted pair copper telephone line, across existing ISDN lines, at a rate of 144 kbit/s, slightly higher than a bonded dual channel ISDN connection at 128kbit/s.
		The benefits of IDSL over ISDN are that IDSL provides always-on connections and transmits data via a data network rather than the Carriers voice network.
		IDSL also avoids per-call fees by being generally billed at a flat-rate.

	Diamond Lane®...SUPERCOMM 98, Atlanta, June 12, 1998 (Site not responding. Last check: )
		IDSL is based on ISDN Basic Rate 2B1Q transmission technology, using existing ISDN CPE to provide "always on" data service at ISDN speed.
		The IDSL signal is mapped into ATM cells in the Diamond Lane Speedlink Multi-service Access Multiplexer to avoid burdening the lower speed IDSL lines with ATM cell overhead.
		The Speedlink IDSL line card allows service providers to further leverage their investments in ATM transmission and switching facilities already providing efficient ADSL and SDSL ATM services and avoid the added expense and space requirements of duplicative frame relay transmission and switching costs characteristic of older IDSL-only systems.
