    • Internet Service Providers
    • ISP
      • company which offers their customers access to the Internet
      • connects to its customers using a data transmission technology
    • Typical home user connection
      • DSL
      • Broadband wireless access
      • Cable modem
      • ISDN
      • FTTX
    • Typical business type connection
      • DSL
      • SHDSL
      • Ethernet technologies
    • DSL ( Digital Subscriber Line )
      • DSL or xDSL , is a family of technologies that provides digital data transmission over the wires of a local telephone network
      • the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service level implemented.
    • Wireless Broadband
      • Wireless Broadband is a fairly new technology that provides high-speed wireless internet and data network access over a wide area.
      • According to the 802.16-2004 standard, broadband means 'having instantaneous bandwidth greater than around 1 MHz and supporting data rates greater than about 1.5 Mbit/s.
    • Cable Modem
      • A cable modem is a type of modem that provides access to a data signal sent over the cable television infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable internet, taking advantage of the high bandwidth of a cable television network. They are commonly found in Australia, New Zealand, Canada, Europe, Costa Rica, and the United States.
    • FTTX
      • Fiber to the x ( FTTX ) is a generic term for any network architecture that uses optical fiber to replace all or part of the usual copper local loop used for telecommunications.
    • ISDN
      • ISDN is a circuit-switched telephone network system, that also provides access to packet switched networks,
      • designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better voice quality than an analog phone.
      • offers circuit-switched connections (for either voice or data), and packet-switched connections (for data), in increments of 64 kbit/s.
      • ISDN typically provides a maximum of 128 kbit/s in both upstream and downstream directions (which can be considered to be broadband speed, since it exceeds the narrowband speeds of standard analog 56k telephone lines).
      • ISDN B-channels can be bonded to achieve a greater data rate, typically 3 or 4 BRIs (6 to 8 64 kbit/s channels) are bonded.
    • SHDSL
      • Single-Pair high-speed digital subscriber line (SHDSL) is a telecommunications technology for Digital Subscriber Line (DSL) subscriber lines. It describes a transmission method for signals on copper pair lines, being mostly used in access networks to connect subscribers to Telephone exchanges or POP Access Points.
      • G.SHDSL was standardized in February 2001 internationally by ITU-T with recommendation G.991.2.
      • G.SHDSL features symmetrical data rates from 192 kbit/s to 2,304 kbit/s of 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.
    • Satellite Internet
      • Enterprises like Starband, Direcway and Wildblue offer satellite Internet service. With an exterior-mounted mini-dish and a proprietary digital modem inside the home, Internet connections can be established over a satellite link similar to satellite television services.
    •  
    • POP(Point of presence)
      • An Internet point of presence is an access point to the Internet. It is a physical location that houses servers, routers, ATM switches and digital/analog call aggregators. It may be either part of the facilities of a telecommunications provider that the Internet service provider (ISP) rents or a location separate from the telecommunications provider. ISPs typically have multiple POPs, sometimes numbering in the thousands. POPs are also located in Internet exchange points and collocation centres.
    • Internet POP Design
      • Point of Presence (POP)
        • An access point to the Internet
        • A router is required to interface with the service provider
        • Demarcation point is where the ISP company ends and the private network of the customer begins.
