Ericsson - IP core network (switching, routing, control and transport)

1 Ericsson's core network solutions include the mobile softswitch, IP

infrastructure, IMS, media gateways, Mobile Packet Backbone Network

(MPBN) and microwave and optical transport solutions to provide

management of voice and data traffic.


Telecommunications in India

1 Telephone Industry in the country which is in an ongoing process of transforming into

next generation network, employs an extensive system of modern network elements such as digital telephone

exchanges, mobile switching centres, media gateways and signalling gateways at the core, interconnected by a wide variety of transmission systems using fibre-optics or

Microwave radio relaynetworks


Next-generation network - Underlying technology components

1 The most important function of the Softswitch is creating the interface to

the existing telephone network, PSTN, through Signalling Gateways

and Media Gateways


Media Gateway Control Protocol

1 The Media Gateway Control Protocol (MGCP) is an implementation of the

Media Gateway Control Protocol architecture for controlling media gateways on Internet Protocol (IP) networks connected to the public

switched telephone network (PSTN)


Media Gateway Control Protocol - Architecture

1 MGCP assumes a call control architecture where there is limited intelligence at the edge (endpoints, Media Gateways) and intelligence at

the core Call Agent. The MGCP assumes that Call Agents, will

synchronize with each other to send coherent commands and responses to the gateways under their control.


Private branch exchange - Current trends

1 Since people want to call from the IP network to the circuit-switched PSTN (Signalling System No. 7|SS7/ISDN

User Part|ISUP), the hosted solutions include interconnecting media

gateways.


AudioCodes - Company history

1 This was followed by the high density media gateways and media servers

and more currently they have entered the market for multi-service business gateways and IP phones.


VxWorks - Networking and communication components

1 * Mitel Networks' Mitel Communications Director (MCD),

3300 ICP Media Gateways and SX-200 and SX-200 ICP.


3Com - Former subsidiaries

1 Robotics provided media gateways (the Total Control 1000 product line,

formerly used for dial-modem termination) and softswitch

technology

Softswitch

1 A call agent may control several different media gateways in

geographically dispersed areas via a TCP/IP link

Media Gateway Control Protocol (Megaco) - Protocol Overview

1 H.248 is meant to address the relationship between the Media Gateways (MGs), which

converts circuit-switched voice to packet-based traffic, and the Media Gateway Controller (MGC).

[http://www.javvin.com/protocol/megaco-h248v2.pdf], The H.248 Gateway Control Protocol version 2 Media Gateway Controller (MGC) using

H.248 instructs one or more Media Gateways (MG)s to connect streams coming from outside a packet or cell data network onto a packet or cell stream such as the Real-time Transport Protocol|

Real-Time Transport Protocol.



1 H.248/Megaco due to its master - slave nature does not describe the

establishment of calls across domains or across Media Gateway Controllers.

H.248/Megaco is used for communication downward, to the media gateways and does not constitute a complete system. The architecture requires a Peer-to-Peer

for communication between Media Gateway Controllers.



1 H.248 defines the protocol for Media Gateway Controllers to control Media

Gateways for the support of multimedia streams across IP

address|IP networks and the Public Switched Telephone network (PSTN)



1 While a Media Gateway Controller (MGC) will use H.248/Megaco to

manage media establishment and control with a number of Media

Gateways (MG), other VoIP protocol such as Session Initiation Protocol|SIP

and H.323 are used for one Media Gateway Controller (MGC) to

communicate with another Media Gateway Controller (MGC)



1 In IP Multimedia Subsystem|IP Multimedia Subsystem (IMS), Media Gateway Control Function (MGCF) control Media Gateways (MGW)s to send

and receive call to / from the PSTN Circuit switching|circuit switched (CS) networks using. H.248. The

MGCF uses SIP messages to interact with IP_Multimedia_Subsystem#CSCF_.E2.80.93_Call_Session_Control_Function|Call Session Control Function

(CSCF) and IP_Multimedia_Subsystem#CSCF_.E2.80.93_Call_Ses

sion_Control_Function|Breakout Gateway Control Function (BGCF).


Internet telephony service provider

1 Retail customers of an ITSP may use traditional analog telephone sets attached to an analog telephony adapter (ATA) to connect to the

service provider's network via a local area network, they may use an IP

phone, or they may connect a private branch exchange (PBX) system to the

service via media gateways.


Media Gateway Control Protocol (MGCP)

1 The 'Media Gateway Control Protocol' ('MGCP') is an implementation of the

Media Gateway Control Protocol architecture for controlling media gateways on Internet Protocol (IP) networks connected to the public

switched telephone network (PSTN).RFC 2805, Media Gateway Control Protocol Architecture and

Requirements, Nhttps://store.theartofservice.com/the-media-gateways-toolkit.html

Media Gateway Control Protocol (MGCP) - Architecture

1 MGCP assumes a call control architecture where there is limited intelligence at the edge (endpoints,

Media Gateways) and intelligence at the core Call Agent. The MGCP assumes that Call Agents, will

synchronize with each other to send coherent commands and responses to the gateways under their control.


PABX - Current trends

1 For the option to call from IP network to the circuit-switched PSTN

(Signalling System No. 7|SS7/ISDN User Part|ISUP), the hosted solutions

include interconnecting media gateways.


GENBAND - History

1 In 2007, Genband acquired Tekelec’s Switching Solutions Group, which expanded Genband’s product offerings in applications software and SIP trunking gateways. In 2008, the company acquired Nokia Siemens Networks’ Surpass

HiG media gateway product portfolio, including fixed-line trunking media gateways.

The company concluded 2008 with the acquisition of NextPoint Networks, which

million at the end of June, 2013.http://www.ndtv.com/article/india/india-to-have-243-million-internet-users-by-june-2014-report-476987 Major

sectors of the Indian telecommunication industry are telephony, internet and television broadcast Industry in the country which is in an ongoing process of transforming into next generation network, employs an extensive system of
