USER PREMISES TELECOM EQUIPMENT NOVEMBER 17 - 21, 1997, SAN ANTONIO, TX TR-41.1 MULTI-LINE TELECOMMUNICATION SYSTEMS T1E1 LIAISON TR-41.1/97-11-037 (C. Sacco, Bellcore) provides the T1E1 liaison. The contribution notes the continuing work on T1.401 (Interface Between Carriers and Customer Installations - Analog Voicegrade Switched Access Lines with Distinctive Alerting Features) with a completion target of end of 1998, and the expected approval and publication of the Enhanced 911 Public Safety Answering Point (PSAP) access standard following passing of the third default ballot. Also noted was the intent to complete revision work on the merged T1.403 (Network-to-Customer Installation - DS1 Metallic Interface) and T1.408 (ISDN Primary Rate - Customer Installation Metallic Interfaces, Layer 1 Specification) standards at the T1E1.2 December 1997 meeting. TIA-464B: R EQUIREMENTS FOR PRIVATE BRANCH EXCHANGE (PBX) SWITCHING EQUIPMENT (A) Living List for Future Revision TR-41.1/97-11-030 (R. Frank, Siemens) provides the current living list for the TIA-464-B (PBX standard) update. There were no major changes to the living list. (B) Comparison of TIA-464B to the New Harmonized FCC Part 68 TR-41.1/97-11-033 (J. Schick and E. Hansson, Nortel) provides an overview comparison between the Harmonized FCC Part 68 and TIA-464-B. Several minor discrepancies were identified; in most cases, these will result in modifications for the next TIA-464 issue. These modifications will be added to the 464 update living list; in a few cases, errors noted in the Part 68 document will be brought to the FCC’s attention. (C) Line-Side Interface Requirements TR-41.1/97-11-032 (J. Schick, Nortel) provides the Project Request and Authorization (PR&A) form for writing a Technical Service Bulletin (TSB) for Basic Rate Interface (BRI) Terminal Lineside Interconnection to Multi-Line Telecommunications Systems (MLTS). It uses the scope and purpose text from an earlier contribution, TR- 41.1/97-08-023 (J. Needham, Mitel and P. Weismantel, NEC). To avoid a possible commitment of evolving this TSB to a standard, a portion of the scope text from that contribution was changed. The PR&A was approved by the TR-41 Plenary and was sent to TIA for project number assignment. In a related matter, TR-41.1/97-11-031 (P. Melton, Cortelco) provides the initial returns/ responses of the North American ISDN Users Forum (NIUF) survey of BRI terminal manufacturers on their characteristics and requirements for interfacing with the BRI line-side of PBXs. As there were only eight responses (Arescom, Cortelco, Interack, ITK, Jetstream, Lucent, Stollmann, Tone Commander) to date, the results have not been summarized or combined; NEC agreed to do so for the next meeting. Other contributions promised for the next meeting include a description of what a BRI terminal should do (Mitel), and a BRI functional specification from the terminal perspective (Cortelco).

  • Ethernet/Category 5 Network Cabling Guide Prepared by SJ Wilkinson (August 2002) Based on Steve Derose’S Guide to CAT5 Network Wiring (See Later Web Reference)
    Ethernet/Category 5 Network Cabling Guide Prepared by SJ Wilkinson (August 2002) Based on Steve DeRose’s Guide to CAT5 Network Wiring (See later Web Reference) Networks A Local Area Network (LAN) can be as simple as two computers, each having a network interface card (NIC) or network adapter and running network software, connected together with a crossover cable. Here the crossover cable would have a plug at either end to connect into the NIC socket at the back of each computer. The next step up would be a network consisting of three or more computers and a hub. Each of the computers is plugged into the hub with a straight-thru cable (the crossover function is performed by the hub). For a small network the straight-thru cables would have plugs at either end – one to connect to the computer and one to the hub. For larger networks wall cabling, wall sockets and patch cables are used. A CAT5 "patch panel" is used at the hub end where all your wires come together and provides a group of sockets for further cables. Straight-thru patch cables connect computers to sockets (jacks). Straight-thru wall cables connect sockets to the patch panel. Straight-thru patch cables connect the patch panel to the hub. Patch panels often make network cabling neater but are not essential as (a) wiring a plug is no harder than wiring a panel; (b) you still need cables to go from the panel to the hub; and (c) it adds extra connections, so lowers reliability. 1 Planning your Network Pick a location for your hub, preferably centred to keep cable runs shorter.

INTRODUCTION: Network, according to Thesaurus Dictionary is “any complex, interlocking system”. According to the Dictionary web, for radio and television, “is a group of tramsmitting stations linked by wire or microwaves so that the same program can be broadcast”, for electricity, “is an arrangement of con- ducting elements, as resistors,capacitors, or inductors, connected by conducting wire”. In telecommunications, network is a system containing any combination of computers, printers, terminals, audio, visual display devices and telephones, interconnected by cables to transmit or receive information. A network can consist of two computers, or millions of computers connected with cables or optical fibers, that are spread over a large geographical area, such as telephone lines, active equipment, radio, television and all visual or communication devices.

  • Getting Physical with Ethernet
    ETHERNET GETTING PHYSICAL STANDARDS • The Importance of Standards • Standards are necessary in almost every business and public service entity. For example, before 1904, fire hose couplings in the United States were not standard, which meant a fire department in one community could not help in another community. The transmission of electric current was not standardized until the end of the nineteenth century, so customers had to choose between Thomas Edison’s direct current (DC) and George Westinghouse’s alternating current (AC). IEEE 802 STANDARD • IEEE 802 is a family of IEEE standards dealing with local area networks and metropolitan area networks. • More specifically, the IEEE 802 standards are restricted to networks carrying variable-size packets. By contrast, in cell relay networks data is transmitted in short, uniformly sized units called cells. Isochronous , where data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also out of the scope of this standard. The number 802 was simply the next free number IEEE could assign,[1] though “802” is sometimes associated with the date the first meeting was held — February 1980. • The IEEE 802 family of standards is maintained by the IEEE 802 LAN/MAN Standards Committee (LMSC). The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, Bridging and Virtual Bridged LANs. An individual working group provides the focus for each area.

  • Cat 6 Cable: Copper's Last Stand?
    Cat 6 Cable: Copper’s Last Stand? Cat 6 Cable is craft intensive! Advanced Installation & service skills are a MUST. 1 Cat6 Cable: Copper's Last Stand? Nope, Not yet! 10Gig IP to the rescue! What is Category 6? Unlike earlier cabling standards Category 6 is a 200MHz classification. The Category 6 standard is an integral part of the 2nd editions of the ISO 11801, TIA 568A and En5017. Initially there were only two parameters proposed for Category 6. These were that any Category 6 solution must use the existing RJ45 plug and jack format. The second was that the Powersum ACR must be positive to 200 MHz. As the standards have developed, additional parameters have been added. These standards continue to be developed and represent the pinnacle of performance for structured cabling systems. The intention behind the Category 6 standard is to provide the state-of-the-art 4-pair cabling system. The different and more stringent handling requirements for Category 6 components demand additional training, even for installers well used to the demands of Category 5e installation practices. Time, care and a high level of technical expertise are essential when installing Category 6. Even slight variations in the termination of links can have a massive effect on the overall performance of the system. It is for these reasons, that it is essential to select an installer who has an existing track record of successfully installing Category 6. With the comprehensive backing of Molex, under the Certified Installer (CI) program, SMT has the experience and track record you need to be sure that your Category 6 solution will perform for you now and in the future.

  • In Tro Duc Tion Glossary of High Speed Terminology
    Connectors High-Speed Glossary of High Speed Terminology Auto-MDIX A protocol which allows two Ethernet devices to negotiate their use of the Ethernet Transmit (Tx) and Receive (Rx) cable pairs. This allows two Ethernet devices with MOl or MDI-X connectors to connect without using a cross-over Introduction cable. Baud A unit of measurement that denotes the number of bits that can be transmitted per second. For example, if a mo- dem is rated at 9600 baud it is capable of transmitting data at a rate of 9600 bits per second. Bandwidth The maximum capacity of a newark channel. Usually expressed in bits per second (bps). Ethernet channels have bandwidths of 10,100, and 1000 Mbps (Gigabit). bps Bits Per Second is the unit used for measuring line speed, the number of information units transmitted per second. Broadcast A transmission initiated by one station and sent to all stations on the network. Byte The amount of memory needed to store one character such as a letter or a number.

  • Computer Ports
    Computer Ports In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices. The term "port" is derived from a Dutch word "poort" meaning gate, entrance or door. ETHERNET PORTS: Ethernet is a family of computer networking technologies for local area networks (LANs) commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies. Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. The standards define several wiring and signaling variants. The original 10BASE5 Ethernet used coaxial cable as a shared medium. Later the coaxial cables were replaced by twisted pair and fiber optic links in conjunction with hubs or switches. Data rates were periodically increased from the original 10 megabits per second, to 100 gigabits per second. Since its commercial release, Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. HISTORY OF ETHERNET: Ethernet was developed at Xerox PARC between 1973 and 1974.[1][2] It was inspired by ALOHAnet, which Robert Metcalfe had studied as part of his PhD dissertation.[3] The idea was first documented in a memo that Metcalfe wrote on May 22, 1973.[1][4] In 1975, Xerox filed a patent application listing Metcalfe, David Boggs, Chuck Thacker and Butler Lampson as inventors.[5] In 1976, after the system was deployed at PARC, Metcalfe and Boggs published a seminal paper.
