  1. ISDN digital subscriber line

    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 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 ...

  1. Rate-Adaptive Digital Subscriber Line

    Unreferenced date December 2008 for RE ADSL2 ITU G.992.3 Annex L DSL technologies Rate Adaptive Digital Subscriber Line RADSL is a variation of Asymmetric Digital Subscriber Line ADSL technology. In RADSL the DSL modem adjusts the upstream networking upstream Bandwidth signal processing bandwidth to create a wider frequency band for the downstream traffic. Using this technique the line is more tolerant of errors caused by Noise physics noise and signal loss. As the frequency is adjusted, the upstream bandwidth may be markedly decreased if there is a large amount of line noise or signal degradation this may reduce the upstream bit rate to as little as 64 kbit s the same speed as a single ISDN B channel .

    Unreferenced stub auto yes date December 2009 DSL technologies MSDSL , or Multi rate Symmetric DSL . is a Digital Subscriber Line technology with a maximum distance of 8,800  m 29,000  ft . It is capable of multiple transfer rates, as set by the Internet service provider , typically based on the service and or price. The maximum speed in both directions is 2 Mbit s. Technology MSDSL is a technology based on 2B1Q transmission with a capacity of 2.32 Mbit s. The bandwidth is split between a full E1 payload 2.048 Mbit s with the remaining bandwidth accommodating up to three voice channels or two ISDN channels. Additional bandwidth is used for management purposes. Transmission over the single pair requires echo cancellation and adaptive equalizers in order to achieve the maximum range at a specific rate. For each user rate, the modem changes the 2B1Q transmission rate, employing different filters and equalizer settings. The modem s adaptive setting is determined during its initial use, and continues constantly during operation.

  1. Single-pair high-speed digital subscriber line

    DSL technologies Single Pair High speed Digital Subscriber Line SHDSL is a form of Digital Subscriber Line DSL , a data communications technology that enables faster data transmission over copper telephone line s than a conventional voiceband modem can provide. Compared to ADSL , SHDSL employs frequencies that include those used by traditional Plain old telephone service POTS to provide equal transmit and receive i.e. symmetric data rates. As such, a frequency splitter, or DSL filter microfilter , cannot be used to allow a telephone line to be shared by both an SHDSL service and a POTS service at the same time. Support of symmetric data rates has made SHDSL a popular choice by businesses for PBX , VPN , web hosting and other data services. SHDSL features symmetrical data rates from 192 kbit s to 2,304 kbit s of Payload software payload in 64 kbit s increments for one pair and 384 kbit s to 4,608 kbit s in 128 kbit s increments for two pair applications. The reach varies according to the local loop loop line rate rate and noise conditions more noise or higher rate means decreased reach and may be up to 3,000 meters.

The interface is also called NET3 for Basic rate interface BRI and NET5 for Primary rate interface PRI lines. Can also be called CTR4 . It is defined by ITU T I.411 ETS 300 102 . It supports Bearer Capability, Low Level Compatibility and High Level Compatibility, ANI, DNIS and redirected number signaling in both directions. DSS1 is a pan Europe an standard developed by ETSI . In 1989 , 26 network operators from 20 European countries decided to develop this standard to replace earlier national protocols such as FTZ 1 TR 6 or VN3 . DSS1 has been one of the keys to the success of the Integrated Services Digital Network ISDN within European countries as compared to, for example, the United States U.S. . Non European countries using DSS1 include Australia , Brazil , Iran , India , Israel , New Zealand , Pakistan , Peru , Singapore , South Africa , Sri Lanka , Taiwan , Palestine and the United Arab Emirates . The DSS1 protocol knows four different codesets for information elements. Codeset 0 regards to Q.931 , Codeset 5 to the ETSI standard, Codeset 6 for national applications and Codeset 7 for PBX applications. The most common Codeset is 0 Q.931.

  1. Digital delay line

    A digital delay line is a discrete element in digital filter theory, which allows a signal to be delayed by a number of samples. If the delay is an integer multiple of samples digital delay lines are often implemented as circular buffer s. This means that integer delays can be computed very efficiently. The delay by one sample is notated math mathrm z 1 math and delays of math N math samples is notated as math mathrm z N math motivated by the role the z transform plays in describing digital filter structures. If a delay is not an integer of a sample additional filters are applied to account for the fraction of delay different from an integer. Hence delay lines with non integer delay are called fractional delay lines . ref Citation last Laakso first Timo I. author link last2 V lim ki first2 Vesa author2 link last3 Karjalainen first3 Matti last4 Laine first4 Unto K. publication date January 1996 date January 1996 title Splitting the unit delay tools for fractional delay filter design periodical IEEE Signal Processing Magazine edition volume 13 issue 1 pages 30 60 publication place place publisher id isbn doi 10.1109 79.482137 oclc url accessdate 2007 08 22 ref Digital delay lines are widely used building blocks in methods to simulate room acoustics , musical instruments and digital audio effects . ref Citation last Smith first Julius O. author link last2 Lee first2 Nelson author2 link publication date August 12 2007 date August 2007 title Computational Acoustic Modeling with Digital Delay url http ccrma.stanford.edu realsimple Delay Delay lines.html accessdate 2007 08 21 ref Digital waveguide synthesis shows how digital delay lines can be used as sound synthesis methods for various musical instruments such as string instruments and wind instruments .

The telephone exchange s are connected via E carrier E1 or T carrier T1 trunks which transport the speech from the calls.

The SLC Remote Terminal RT is typically located in a remote from the telephone company central office area with a high density of telephone service such as a residential neighborhood. Two or four Digital Signal 1 T1 circuits depending on the configuration connect the SLC RT back to the Central Office Terminal COT in the case of a Universal Subscriber Loop Carrier USLC . An Integrated Subscriber Loop Carrier ISLC has its T span s terminating directly in time division switching equipment in the telephone exchange . One system serves up to 96 customers. This configuration is more efficient than the alternative of having separate copper pairs between each service termination point house and the central office .

  1. Subscriber trunk dialling

    Subscriber trunk dialling STD , also known as subscriber toll dialing is a term for a telephone system allowing subscribers to dial trunking trunk calls without telephone operator operator assistance. Terminology As well as the UK, the term subscriber trunk dialling is used in other countries such as the Republic of Ireland , Australia and India .
