  2. Network switching subsystem - Wikipedia

    en.wikipedia.org/wiki/Network_switching_subsystem

    Network switching subsystem. Network switching subsystem (NSS) (or GSM core network) is the component of a GSM system that carries out call out and mobility management functions for mobile phones roaming on the network of base stations. It is owned and deployed by mobile phone operators and allows mobile devices to communicate with each other ...

  3. Binary Synchronous Communications - Wikipedia

    en.wikipedia.org/wiki/Binary_Synchronous...

    Binary Synchronous Communications. Binary Synchronous Communication (BSC or Bisync) is an IBM character-oriented, half-duplex link protocol, announced in 1967 after the introduction of System/360. It replaced the synchronous transmit-receive (STR) protocol used with second generation computers. The intent was that common link management rules ...

  4. Base station subsystem - Wikipedia

    en.wikipedia.org/wiki/Base_station_subsystem

    The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, paging, transmission and reception over ...

  5. Communication protocol - Wikipedia

    en.wikipedia.org/wiki/Communication_protocol

    The need for protocol standards can be shown by looking at what happened to the Binary Synchronous Communications (BSC) protocol invented by IBM. BSC is an early link-level protocol used to connect two separate nodes. It was originally not intended to be used in a multinode network, but doing so revealed several deficiencies of the protocol.

  6. Binary symmetric channel - Wikipedia

    en.wikipedia.org/wiki/Binary_symmetric_channel

    A binary symmetric channel (or BSC p) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit. The bit will be "flipped" with a "crossover probability" of p, and otherwise is received correctly.

  7. Reserved IP addresses - Wikipedia

    en.wikipedia.org/wiki/Reserved_IP_addresses

    Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255

  8. Mobile Telephone Switching Office - Wikipedia

    en.wikipedia.org/wiki/Mobile_Telephone_Switching...

    The Mobile Telephone Switching Office (MTSO) is the mobile equivalent of a PSTN Central Office. The MTSO contains the switching equipment or Mobile Switching Center (MSC) for routing mobile phone calls. It also contains the equipment for controlling the cell sites that are connected to the MSC. The systems in the MTSO are the heart of a ...

  9. Routing table - Wikipedia

    en.wikipedia.org/wiki/Routing_table

    The network address and subnet mask of the interface, along with the interface type and number, are entered into the routing table as a directly connected network. A remote network is a network that can only be reached by sending the packet to another router. Routing table entries to remote networks may be either dynamic or static.
