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

Features

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
