Telecommunications in India

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
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

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
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
H.248 is meant to address the relationship
between the Media Gateways (MGs), which
converts circuit-switched voice to packetbased traffic, and the Media Gateway
Controller
(MGC).[http://www.javvin.com/protocol/me
gaco-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
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)

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.
