    • DSP Technology
      • DSP - Digital Signal Processor
    • Does the electronic processing and simulation of signals
    • DSP is a special kind of processor which is used to perform a specific application
    • Capable of doing rapid numeric processing
    • Capable of performing Real-Time computations
    • Controls all functions for which it is programmed
    • Consumes Less Power
    • Occupies less space on PCB die to its compact size
      • Codec Technology
        • Voice is encoded from analog to digital IP Packets
      • Signals are decoded back to analog Voice at receiver end Codec supported by Setu ATA are G.711 A-Law, ?Law, G.723, G.729A, G.729B
        • SMT Design
          • Smaller and Lighter components
        • Simpler automated assembly
        • Error free component placement on PCB
        • Components can be mounted on both sides of the PCB
        • Lower lead resistance and inductance
        • Better performance for high frequency parts
        • Better mechanical performance under shake and vibration conditions
          • SLIC Based Design
            • SLIC IC at FXS Interface
          • Functions performed by single SLIC IC
          • B - Battery Feed
          • O - Over Voltage Protection
          • R - Ringing
          • S - Supervision
          • C - Coding
          • H - Hybrid
          • T - Test
          • No need of a separate PCB on the main circuit board or in the system
  • Peer-to Peer Calling
    • Allows User to Call Another ATA or Softphone, Which is in the same LAN (Same Location) or Virtual LAN (Different Locations)
  • Setu ATA can call other ATA's Extension Number or Softphone without going through Proxy
  • Extension Number of Remote ATA along-with its' IP Address is Programmed in Peer-to-Peer calling Table
  • Total 64 Numbers Can be Programmed in Table as shown below:
    • Voice Activity Detection (VAD)
      • It is Software Application
    • It allows detection of the Absence of Audio during Speech
    • It Prevents the Transmission of " Silence Packets" over network
    • When silence is observed, ATA does not send any acket on
    • Network, which saves Bandwidth Utilization
    • It is also Called 'Silence Suppression'
    • VAD can be Enabled / Disabled to monitor signals over Voice Activity
    • However when VAD is Enabled Voice Quality is Degraded as
    • Less Bandwidth is available for communication
      • QoS - Quality of Services
        • QoS - Capability of a Network to Provide Better Service
      • QoS is measured for various technologies like:
      • > Frame Relay, ATM. SONET
      • > Ethernet, 802.11 Networks
      • > Other IP Routed Networks
      • QoS is required to provide priority on Bandwidth allocation,
      • Controlling Jitter and Latency
      • QoS provides improved Voice Quality
      • Setu ATA2LL Supports Two Types of QoS : ToS and DiffServe
      • > ToS (Type of Service): Server Decides Best Method of
      • delivering data like LCR, Fastest Route
      • > DiffServe (Differentiated Services) : It is like Class of Service,
      • based on application types and traffic flow. Data Packets
      • are marked with DiffServe Code Point indicating level of
      • service desired
        • NAT - Network Address Translation
          • NAT - A technology used by Firewalls and Routers
        • It allows multiple devices having private IP to work on a LAN
        • to share a single public IP Address
        • It translates private IP address into public IP address
        • Translation is required for a device to communicate with
        • other device on internet
        • A Router doing such translation is known as a NAT Router
        • NAT Router replaces source IP (Private IP) with its Own
        • public IP before passing the traffic to the destination on Internet
        • When a response is received, NAT Router searches its translation
        • tables for Original Source Address from which device has started
        • the Connection and then passes the response to that Device
        • NAT is also called as 'IP Masquerading'
        • Traffic Passing through NAT is called as 'NAT Traversal'
          • STUN
            • STUN - Simple Traversal of UDP over NATs
          • UDP (User Datagram Protocol) is a Network Protocol for Transmitting Data that does not require acknowledgement from the recipient for the Data that is sent.
          • STUN allows ATA to work behind Asymmetrical NAT
          • STUN is a Client-Server protocol allowing the Client behind NAT to find out its Public Address, Type of NAT and Internet Side Port
          • STUN Client (like ATA) sends a request to STUN server
          • The server reports back to the STUN Client with the Public IP address of NAT Router and which port is Opened by NAT to allow incoming Traffic back into the Network
