SDSL definition

SDSL or "Symmetric Digital Subscriber Line" is a baseband DSL transmission technology that permits the bi-directional transmission from up to 160 kbps to 2.048 Mbps on a single pair. "VDSL" or "Very High Speed Digital Subscriber Line" is a baseband DSL transmission technology that permits the transmission of up to 52 Mbps downstream (from the Central Office to the End User Customer) and up to 2.3 Mbps digital signal upstream (from the End User Customer to the Central Office). VDSL can also be 26 Mbps symmetrical, or other combination.

SDSL means symmetric digital subscriber line.

SDSL or "Symmetric Digital Subscriber Line" is a baseband DSL transmission technology that permits the bi-directional transmission from up to 160 kbps to 2.048 Mbps on a single pair. “SHDSL” or “Singe-Pair High Speed DSL” provides for sending and receiving high-speed symmetrical data streams over a single pair of copper wires. The SHDSL payload may be 'clear channel' (unstructured), T1 or E1 (full rate or fractional), multiple ISDN Basic Rate Access (BRA), Asynchronous Transfer Mode (ATM) cells, or Ethernet packets. “G.SHDSL” or “Symmetric High Bit Rate DSL” features symmetrical data rates from 192 kbit/s to 2,304 kbit/s of payload in 64 kbit/s increments per pair. “E.SHDSL” or “Extended Singe-Pair High Speed DSL” offers symmetrical data rates of up to 5,696 kbit/s in 64k increments per a pair. SHDSL is based on ITU standard G.991.2 with additional coverage of E.SHDSL in 802.3ah. "VDSL" or "Very High Speed Digital Subscriber Line" is a baseband DSL transmission technology that permits the transmission of up to 52 Mbps downstream (from the Central Office to the End User Customer) and up to 2.3 Mbps digital signal upstream (from the End User Customer to the Central Office). VDSL can also be 26 Mbps symmetrical, or other combination. “Embedded Base xDSL Capable Loop” refers to an xDSL Capable Loop (including ADSL Compatible Loop and Non-Loaded Loop) installed for CLEC before the Final Implementation Date of this Amendment.

Examples of SDSL in a sentence

• If RNK submits a service order for an ADSL, HDSL, SDSL, IDSL or BRI ISDN Loop that has not been prequalified on either a mechanized or manual basis, Verizon will query the service order back to the CLEC for qualification and will not accept such service order until the Loop has been prequalified on a mechanized or manual basis.

• If RNK submits a service order for an ADSL, HDSL, SDSL, IDSL or BRI ISDN Loop that is, in fact, not compatible with such services in its existing condition, Verizon will respond within a reasonable time to RNK with a “Nonqualified” indicator and with information showing whether the non-qualified result is due to the presence of load coils, presence of digital loop carrier, or loop length (including bridged tap).

• If the Loop is served out of a Central Office that has not been prequalified on a mechanized basis, RNK must request a manual loop qualification prior to submitting a valid electronic service order for an ADSL, HDSL SDSL, ISDL, or SRI ISDN Loop.

• We offer products and services to our business customers by providing access to our network via: • direct fiber access from over 6,000 fiber access points; • more than 280 of our DPoPs providing 2 Mbps SDSL (planned to increase to 8 Mbps service using Swisscom copper twisted pairs); • leased lines; and • our coaxial cable access network.

• Notwithstanding anything contained in this Agreement, AWARE may provide its ADSL, SDSL, HFC and any other general data communication product (not including lossy compression) to third parties for Medical Use or any other purpose.

SDSL provides a symmetric service level speed objective of approximately 1.5 mbps downstream and 1.5 mbps upstream. Because this service is distance dependant – no actual speed objective is provided or guaranteed. This service level is available as a private network or with Internet Services. A UBR (Unspecified Bit Rate) for Best Effort delivery with defined shaping level is used. The underlying Transport service provided by the Telco (which includes ATM and Ethernet) includes the overheads (headers and trailers) associated with the transport service. The CUSTOMER accepts that such overheads reduce the effective burst and sustained throughput available for the data of the CUSTOMER. Bandwidth in this service class in not guaranteed since it is dependent on third part variables such as available Third party transport; distance from the Telco provided central office and other conditions that are beyond the control of Activo.
