• EC 210
• VOIP Terms 31-45

2
Throughput

• The actual amount of useful and non-redundant
  information which is transmitted or processed.
  End result of a data call. Throughput is a
  function of bandwidth, error performance,
  congestion, and other factors.

3
UPS

• Uninterruptible Power Supply (source) a device
  that keeps clean power to network systems
  protects against blackouts, brown outs, spikes,
  surges, EMI, RFI.

4
Media Gateway Control Protocol

• A protocol for the control of VOIP calls by
  external call control elements known as media
  gateway controllers, or softswitches. The
  protocol defines a means of communication between
  a media gateway. It converts data from circuit
  switched networks to required data in a packet
  switched network.

5
Softswitch

• 3rd generation central office, IP technology used
  to merge traditional circuit switched systems
  with packet switched systems. Technology in a
  softswitch is software (hence the name) rather
  than in hardware as with traditional switching
  technology

6
Session Initiated Protocol

• The most important standard for setting up
  telephone calls on the internet. SIP is an
  application layer (7) on the OSI model, for the
  establishment, modification and termination of
  telephony of over IP based networks.

7
Direct Inward Dial

• Ability to dial into a company without going
  through an attendant (operator), an exclusive
  feature on PBXs.

8
H.323

• Standards from ITU-T which serves as the umbrella
  for a set of standards defining real time
  communications for packet based networks IP
  telephony. Defines a set of call control, channel
  setup and codec specifications for transmitting
  real time voice/video over packet networks

9
Codec

• CODer/DECoder or Compression/DECompression.
  Converts voice signals from their analog form to
  digital signals acceptable to digital PBXs and
  digital transmission systems, then converts back
  to analog.

10
Realtime Transport Protocol

• Standard for streaming real time multimedia over
  IP in packets. Supports transport of real time
  data like interactive voice and video over packet
  switched networks.

11
Real Time Control Protocol

• The protocol by which VOIP QoS information is
  communicated.

12
Frame Relay

• High performance WAN protocol that operates at
  the physical and data link layers of the OSI
  model. An example of packet switching technology.

13
Asynchronous Transfer Mode

• Very high speed transmission technology, a high
  bandwidth, low delay, connection oriented, packet
  like switching and multiplexing technique.

14
Ethernet

• LAN technology used for connecting computers,
  printers, servers, etc.

15
MultiLink Point to Point Protocol

• A method by which packet data traffic can be
  spread across multiple WAN links in order to
  increase transmission speed. Provides for packet
  fragmentation and reassembly, sequencing and load
  balance for inbound/outbound traffic.

16
Point to Point Protocol

• Layer 2 Data Link protocol that allows to devices
  to transport packets over a simple link, example
  your home PC to your ISP.

17
