	SHDSL Frequently Asked Questions
		SHDSL is designed to transport rate-adaptive symmetrical data across a single copper pair at data rates from 192 kbps to 2.3 Mbps or 384 kbps to 4.6 Mbps over two pairs.
		SHDSL stands for Symmetric High-Bitrate Digital Subscriber Loop.
		An analog lifeline, like with ADSL, is not possible with deployments using SHDSL.

	SHDSL: DSL in overdrive
		SHDSL�s ability to support multiservices will enable service providers to deliver integrated communications solutions, including voice, video and videoconferencing.
		SHDSL is also rate adaptive, allowing flexible revenue-generation models and enabling service providers to offer service-level agreements that ensure businesses get the service they want, when they want it.
		SHDSL meets the needs of business, with such comprehensive solutions for the SMB and enterprise branch office markets as security, virtual private networks and business contingency planning.

		SHDSL (Single-pair High bit-rate Digital Subscriber Line) is a dedicated business-grade service that delivers symmetric speeds of up to 1.5 Mbps.
		A. While we are confident that our traditional AceDSL® service, based on ADSL technology, can adequately fulfill the needs of even the most demanding Internet user, we also believe that some of you can extract more value and peace of mind from SHDSL.
		SHDSL service can be provisioned in a fraction of time it takes to install a traditional T1 loop.

	PCWorld.com - Superfast DSL Could Take Broadband Market by Storm
		SHDSL is also able to reach 20,000 feet from central-office switches, and repeaters can extend that to a theoretical limit of 19 miles, says Shaheen Kazi, director of product marketing at Efficient Networks.
		SHDSL is expected to catch on faster in Europe than in the United States because of Europe's slow adoption of SDSL.

	Big Blue Internet - Broadband Products
		SHDSL (Symmetric High-speed Digital Subscriber Line), part of the xDSL family of related technologies that includes ADSL, offers several advantages over the better known ADSL.
		SHDSL is primarily available in metropolitan areas, and can provide connection speeds of up to 8 Mb/s.
		Its offers the same speeds for uploading and downloading data, and is therefore ideal for creating cost-effective VPNs and other application sharing functions.

		Armstrong insists that SHDSL wholesale rollout is going to be a 'huge project', but that's largely because BT has no symmetrical DSL line cards in its DSLAMs.
		How much that 'lack of demand' was down to unfavourable co-location conditions can be debated ad nausea, but the fact still remains that BT did not make any provision for SHDSL until it was forced to by the regulator.
		"Even though we've received no official request from either Energis and Thus, we'll still have SHDSL wholesale products ready on a trial basis by this autumn," says Neil Armstrong, product marketing manager for BT Wholesale.

	RFC 3276 (rfc3276) - Definitions of Managed Objects for High Bit-Rate DSL
		Since span configuration parameters are only applicable for SHDSL, the support for span configuration profiles are optional for HDSL2 interfaces.
		For those conditions where the number of provisioned repeaters is less than those encountered during span discovery, additional table entries are to be created using the default span configuration profile.
		Counters, Interval Buckets and Thresholds For SNR Margin, Loop Attenuation, ES, SES, CRC anomalies, LOSW, and UAS, there are event counters, current 15-minute and 0 to 96 15- minute history bucket(s) of "interval-counters", as well as current and 0 to 30 previous 1-day interval-counter(s).

		G.shdsl is a popular digital subscriber line (DSL) service that offers symmetrical data rates high enough to support multi-channel voice, Web hosting, video teleconferencing, e-mail and other services.
		The M28976's dual bearer operation is fully compliant with Annex E.10 of ITU G.991.2, the technical specification for G.shdsl.

	Broadband Access: G.SHDSL: Reaching the Access Network
		The G.SHDSL standard, now in the final stages of definition by the ITU, is a new international standard for symmetric DSL (SDSL).
		G.SHDSL has been designed specifically for symmetric data transfers, allowing upstream and downstream data transfers in excess of 2 Mbps over a single pair of copper wires.
		While G.SHDSL uses a much-simplified PSD and lower transmit power than HDSL2, many of the functional blocks are the same.
