Modem

Modem

  • Allows modems of different vendors to operate together

  • Define How modems operate:

    • Modulation techniques

    • Data compression technique

    • Error detection strategy


Modem analog vs digital

Modem – Analog vs Digital

  • Analog

    • Infinite number of levels

    • Conform to voice pattern

    • Times from highest to lowest and back to the highest point in one second is the frequency

    • Can be transmitted over long distance

  • Digital

    • Only two levels (high and low)

    • Conforms to how computers operate

    • Cannot transmitted over long distance

Dvb dvb ip tech

DVB – DVB/IP Tech

  • The Digital Video Broadcast over Internet Protocol (DVB/IP) system is functionally an IP-over-Ethernet simplex satellite service that incorporates frame-relay type traffic management. At its core, DVB is a modem-on-a-chip, plus an intelligent multiplexer. The antenna is typically a CATV dish, 2.4 - 3.8 meters in diameter (for C-band), or 0.6 -1.8 meters (for Ku-band).

Twisted pair

Twisted Pair

  • Two wired wrapped in a twisted fashion

    • Designed to reduce cross-talk due inductance

    • Still subject to interference from stray signal

  • Primarily used for local loop connections and LANs

  • Comparatively narrow bandwidth

Coaxial

Coaxial

  • Center lead conducts the signal

    • Protected by insulation and braded wire

  • Used mostly for television and connections to antenna

  • Larger Bandwidth but large in size

Hub versus switch

Hub versus Switch

  • Hub provide connection to all ports (i.e. in one port and out all other ports).

    • Passive hub – no signal regeneration

    • Active hub – provide signal regeneration

  • Switch direct the message from appropriate port (directs a message from the input port to the desired output port).

    • More expensive but better bandwidth utilization
