  4. Network-based Call Signaling has been defined by CableLabs as the standard for telephony over HFC (Hybrid Fiber Coax) CATV cable plants. The NCS specification is a CATV- specific enhancement to MGCP (Media Gateway Control Protocol), which is the de facto standard for multimedia call control between the traditional PSTN (Public Switched Telephone Network) and IP-based packet networks. NCS serves as the core of the CableLabs PacketCable architecture. PacketCable is a fast-track initiative aimed at developing interoperable interface specifications for delivering advanced, real-time multimedia services over IP-based packet channels carved out of two-way CATV cable plants. PacketCable is built on the infrastructure set by CableLabs Certified, previously known as DOCSIS (Data Over Cable Service Interface Specification), which sets standards for CATV modems and related network elements supporting high-speed Internet access over CATV networks. PacketCable includes specifications for call signaling, QoS (Quality of Service) control, PSTN interconnection, security, network management, codec support, billing event messages, and network announcements. The NCS signaling occurs between the Multimedia Terminal Adapter/cable modem (MTA) and the NCS Gateway (NCSG), which works as interface between the MTA and the Call Feature Server connected to the CATV network or PSTN. See also CableLabs, CableLabs Certified, CATV, MGCP, and PacketCable.


National Center for Supercomputer Applications. A supercomputer operations and research center located at the University of Illinois at Urbana-Champaign. The NCSA was one of the national supercomputer centers funded by the NSF (National Science Foundation). The six centers were interconnected over a network known as the NSFNET, which originally operated at 56 Kbps, and which was upgraded in 1987 to 1.544 Mbps (T-1) and to 45 Mbps (T-3) in 1989. The NSFNET was essentially disbanded in 1995, in favor of commercialization of the backbone network. See also NSF.


National Center for Supercomputer Applications Network. A regional TCP/IP network which connected users in Illinois, Wisconsin and Indiana. NCSANet was also a mid- level network in NSFNET, which has been abandoned .

  1. A non-disclosure agreement is a signed formal agreement in which one party agrees to give a second party confidential information about its business or products and the second party agrees not to share this information with anyone else for some time ” sometimes as long as five years . NDAs are often signed when a company wants to sell something ” itself or a subsidiary and it doesn't want

    NDAs tend to protect the company more than the individual signing the agreement. As a matter of practice, I've signed very very few NDAs. Most people will show me things because they trust me. Making me sign an NDA is not going to protect them much if I'm not trustworthy. I personally prefer trust and integrity to an NDA.

Novell Directory Services. According to Novell, NDS is a multiple-platform, distributed database that stores information about the hardware and software resources available on a network. It provides network users, administrators and application developers global access to all network resources. NDS also provides a flexible directory database schema, network authentication/security, and a consistent cross-platform development environment. NDS uses objects to represent all network resources and maintains them in a hierarchical directory tree. NDS was originally NetWare Directory Services, but it was changed about 1996 when Novell started to explore putting it on platforms other than NetWare. NDS is now available on a wide variety of platforms, including NetWare, Windows NT, Sun Solaris, Linux (several variants), OS/390, AIX, and Compaq Tru64 UNIX.


Non Dispersion Shifted Fiber is the earliest form of Single Mode Fiber (SMF) developed, and was a considerable improvement over MMF (MultiMode Fiber). NDSF generally runs in the O- Band , at about 1310nm (nanometers). When NDSF was first developed, it was discovered that signals suffered from chromatic dispersion, the phenomenon by which different colors (i.e., wavelengths ) of light travel at slightly different speeds. Since even the most tightly tuned laser light sources create signals composed of multiple wavelengths, each pulse of light contains components that travel at slightly different speeds. The portions of the light pulses that enter the cladding experience this phenomenon to a greater extent, as the cladding is much more pure that the core. Therefore, all signals travel at an accelerated rate through the cladding, and the impact of the phenomenon is more pronounced. The problem is exacerbated by waveguide dispersion, the phenomenon by which higher frequency (shorter wavelength) signals travel more in the cladding (and less in the core) than do lower frequency signals. NDSF runs in the 1310nm window (i.e., wavelength range), as chromatic dispersion and waveguide dispersion cancel each other at that wavelength. Dispersion Shifted Fiber (DSF) is an improvement over NDSF. See also Chromatic Dispersion, DSF, MMF, O-Band, SMF, Waveguide Dispersion, and Window.

NetWare Directory Services. A feature of Novell's NetWare operating system which allows users to sign on to multiple NetWare servers through one simple sign-on. The ultimate idea is that NDS will become somewhat of a front-end sign-on to other networked devices, e.g. telephone systems, voice mail, electronic mail, Lotus Notes, etc. Sign on in one place, get into many. A big user time-saving benefit. A competitor to NDS is Microsoft's ODSI Open Directory Services Interface.

  1. New Equipment Building System.

  2. Network Equipment Building Standards. NEBS defines a rigid and extensive set of performance, quality, environmental and safety requirements developed by Bellcore, the R&D and standards organization once owned by the seven regional Bell operating companies (RBOCs). NEBS compliance is often required by telecommunications service providers such BOCs (Bell Operating Companies) and Interexchange Carriers (IEC) for equipment installed in their switching offices. NEBS defines everything from fire spread and extinguish ability test to Zone-4 earthquake tests to thermal shock, cyclic temperature, mechanical shock , and electro-static discharge . Conforming to NEBS is not inexpensive.

Here is a more detailed explanation of NEBS: NEBS, Generic Equipment Requirement, is a subset of the Family of Requirements as published by Bellcore known as LSSGR, LATA Switching System Generic Requirement. Bellcore has published a technical reference (TR), TR-NWT-000063, Issue 5, 1994, which outlines the NEBS "standard." Bellcore states that the intent of this TR is to " inform the industry of Bellcore's view of the proposed minimum generic requirements that appear to be appropriate for all new telecommunications equipment systems used in central offices (CO) and other telephone buildings of a typical BCC (Bellcore Client Company)."

The requirements defined in this TR are broken into two major categories: 1) spacial requirements and 2) environmental requirements. Spacial requirements apply to the equipment systems' cable distributing and interconnecting frames , power equipment, operations support systems and cable entrance facilities. Compliance with these requirements is intended to improve the use of space in the CO, simplify building-equipment interfaces and help make the planning and engineering of central offices simpler and more economical. In general, the spacial requirements relate to the size and location of the equipment going into a CO, how to power it and how to cable it all together.

The second category relates to environmental requirements that define the conditions under which the equipment could potentially be exposed to and still operate reliably or not cause any catastrophic situation such as fire spread. These environmental requirements include temperature and humidity, fire resistance (which seems to be at the top of many BCCs' lists), shock and vibration (which covers transportation, office and earthquake), electrostatic discharge (susceptibility and immunity) and electromagnetic compatibility (emission and immunity). Bellcore has also defined test methods in this TR which provide procedures on how to test the equipment to ensure that it meets the requirement. See Bellcore.


See National Electric Code.

NEC Requirements

The National Electrical Code (NEC) is written and administered by the National Fire Protection Agency (NFPA). The latest 1990 version states that any equipment connected to the telecommunications networks must be listed for that purpose. Listing is acquired through Underwriters Laboratories (UL) or a similar approved lab. Listing requirements for premises wiring between the Network Interface Device and the modular jack at the work area took effect on October 1, 1990. See NFPNA 90A.


National Exchange Carrier Association. An association of local exchange carriers mandated by the U.S. Federal Communications Commission in 1983, in anticipation of the breakup of the Bell System. NECA's primary responsibility was to file new interstate access tariffs and to perform the " settlement " functions previously performed by AT&T and the BOCs (Bell Operating Companies). Under the direction of the FCC, NECA administers approximately $2 billion in annual revenues , based on pooled tariff rates. Through the pooling process, the LECs (Local Exchange Carriers) bill the IXCs (IntereXchange Carriers) for the use of their local exchange networks in originating and terminating long distance calls. Individual revenues and costs then are submitted to NECA, which distributes them to the member companies on an averaged basis. NECA also administers the Universal Service Fund (USF), the Lifeline Assistance Programs, and the Telecommunications Relay Services Fund. See also Division of Revenues, Lifeline Assistance Programs, Separations and Settlements, Telecommunications Relay Services Fund, and Universal Service Fund.


Network Element Control Protocol. An Internet protocol which provides methods by which network elements (NEs) can learn about the capabilities and availability of services, and which provides hints as to which data flows can and cannot be serviced. Thereby, NECP allows intelligent NEs to perform load balancing across an array of servers, interception and redirection of data flows to transparent proxy servers, and cut-through of data flows to the origin in the event that the proxy servers cannot serve the data flows. See also Cache, Client, Proxy, and Server.

  1. Think about a voice conversation. We call someone. They answer. We say "Joe." They say "Harry." We've identified ourselves . We know each other so we choose the language we speak ” in this case English. This is a simple explanation of what two machines do when trying to speak with each other. When they first start talking, they query each other on speed, protocol, language, etc. etc. This is called "negotiation." For example, if one device is speaking slowly (the line is a slow speed one), the other device will drop (negotiate) its speed down. Here's a more technical explanation: Negotiation is the process whereby two end-points announce their speed (10/100 Mbps) and duplex value (Half/Full) and determine the best values for communication. For example, if a device is connected to an Internet switch port, the network card in the device and the Internet switch port negotiate their speed and duplex values. If the values are different, the lower values are used.

  2. Negotiation also means getting the product or service you want at the price you want to pay. Books have been written on the art of negotiation. For me, the key is to go for the best deal. The worst that can happen is for them to say "NO." If you lose that deal, there's always a better one around the corner.

Negroponte Switch

This term was coined by George Gilder after Nicholas Negroponte, founder of MIT's Media Lab. Negroponte predicted that the advent of personal wireless technologies would cause signals that historically traveled by wireless methods (broadcast television, for example) to "switch" to wireline technologies (such as CATV), and signals that historically traveled by wireline methods (telephone, for example) would switch to wireless (such as cell phones). Negroponte's prediction was based on considerations of efficiency ” cell -based wireless networks are much more efficient in spatial reuse of the spectrum than broadcast networks ” and business opportunity. Broadcasters/content providers seeking to "narrowcast" their content in order to collect more subscription revenues. The model holds up pretty well in developed countries, but less so in other countries where wireline network infrastructure (telephone or CATV plant) may not be as well-developed.

Slang term coined in the 1950s for an unpleasant, unattractive, or insignificant person ” a square, or loser. It would seem that the term clearly was coined by people who considered themselves to be pleasant, attractive, or significant, i.e. winners. One theory traces the term it to a passage in Dr. Seuss' lesser-known 1950 children's book "If I Ran the Zoo." The thought is that Dr. Seuss probably got it from the U.S. Navy acronym NERD, which referred to Naval Enlisted Requiring Discipline, a term commonly used for sailors locked away in the brig. Another theory considers it a variation of the 1940s put- down "nerts to you," as in "nuts to you." Since a lot of nerds are now rich Cybergeeks, the term probably needs to be redefined. See also Geek, Nerb Bird and Nerdistan.

There's only one thing to know about the NetBEUI protocol ” install it. On any networked Windows PC, go to Networking/Properties/Install/Protocol/Microsoft NetBEUI. The reason? Windows machines networked to each other over Ethernet work better and more reliably when NetBEUI protocol is installed. This is irrespective of what Microsoft tells you about its machines happily using the TCP/IP protocol to talk to each other. IN fact they can. But TCP/IP seems to be unreliable in for communicating between PCs on a small local area network. NetBEUI stands for NetBIOS Extended User Interface. It was one of the earliest protocols available for use on networks composed of personal computers. It was designed around the Network Basic Input/Output System (NetBIOS) interface as a small, efficient protocol for use in department- sized local area networks (LANs) of 20 to 200 computers, which would not need to be routed to other subnets. Windows 2000-based NetBEUI, known as NetBIOS Frame (NBF), implements the NetBEUI version 3.0 specification. NBF is the underlying implementation of the NetBEUI protocol installed on a computer running Windows 2000. It provides compatibility with existing LANs using the NetBEUI protocol, and is compatible with the NetBEUI protocol driver included with previous versions of Microsoft networking products. In addition, NBF:

  • Uses the Windows 2000-based Transport Driver Interface (TDI), which provides an emulator for interpretation of NetBIOS network commands.

  • Uses the Windows 2000-based Network Device Interface Specification (NDIS) with improved transport support and a full 32-bit asynchronous interface.

  • Uses memory dynamically to provide automatic memory tuning.

  • Supports dial-up client communications with a remote access server.

  • Provides connection-oriented and connectionless communication services.

  • Removes the NetBIOS session number limit.

Network Basic Input/Output System (NetBIOS) is software developed by IBM. It provides the interface between a computer's operating system, the I/O bus, and the network; a de-facto network standard. NetBIOS Extended User Interface (NetBEUI) is the original personal computer networking protocol and interface designed by IBM for their LAN Manager server. NetBEUI implements the OSI LLC2 protocol and has a limitation of 254 session connections. Windows 2000 NetBEUI 3.0, also known as NetBIOS Frame Format Protocol (NBFP), is the Microsoft implementation of the IBM NetBEUI protocol. It eliminates the previous NetBEUI limitation of 254 sessions to a server and uses the Microsoft TDI layer as an interface to NetBIOS. See NETBIOS.


Network Basic Input/Output System. A layer of software originally developed by IBM and Sytek to link a network operating system with specific hardware. Originally designed as the network controller for IBM's PC Network LAN, NetBIOS has now been extended to allow programs written using the NetBIOS interface to operate on the IBM Token ring. NetBIOS has been adopted as something of an industry standard and now it's common to refer to Netbios-compatible LANs. It offers LAN applications, a variety of "hooks" to carry out inter-application communications and data transfer. Essentially, NetBIOS is a way for application programs to talk to the network. Other applications interfaces are also being used these days, such as IBM's APPC. To run an application that works with NetBIOS, a non-IBM network operating system or network interface card must offer a NetBIOS emulator. More and more hardware and software vendors offer these emulators. They aren't always perfectly compatible, though. Today, many vendors either provide a version of NetBIOS to interface with their hardware or emulate its transport layer communications services in their network products. See NetBEUI.
