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.

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.

Media Gateway Control Protocol (Megaco) - Protocol Overview
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.

Media Gateway Control Protocol (Megaco) - Protocol Overview
1 H.248 defines the protocol for Media Gateway Controllers to control Media

Media Gateway Control Protocol (Megaco) - Protocol Overview
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)

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.
