A leased line (dedicated line) is a permanent fiber optic or
telephone connection between two points set up by a
telecommunications carrier.
They can be used for telephone, data, or internet services.
Businesses use a leased line to connect to geographically
distant offices because it guarantees bandwidth for network
traffic.


The MLLN is a Managed Leased Line Network system
which provides variable bandwidth leased line connectivity.
The State-of-the art technology equipment MLLN is
designed mainly for having effective control, on the leased
lines so that the down time is very much minimized.
This mainly supports with data circuits ranging from
64
KBPs to 2048 KBPs.

24 hrs Performance Monitoring of the circuit.
Circuit fault reports generated proactively.
On Demand the Bandwidth can be increased.
Low lead time for new circuit provisioning.
Protection against the failure of the circuit through
recovery Management process either automatic or
manually.
Long drive on single copper pair.( for 64 kbps & 2mbps)
Centrally managed from ROT connected to the NMS.


In wireless communication every region is divided into cells.
Cell size is constant for whole system.
GSM is a form of multiplexing, which divides the available
bandwidth among the different channels.
GSM differs from its predecessor technologies in that both
signaling and speech channels are digital, and thus GSM is
considered a second generation (2G) mobile phone system.

13. 


The Universal Mobile Telecommunications System
(UMTS) is a third generation mobile cellular system for
networks based on the GSM standard.
UMTS is a component of the International
Telecommunications Union IMT-2000 standard set and
compares with the CDMA2000 standard set for networks
based on the competing CDMA technology.
UMTS uses wideband code division multiple access (WCDMA).

15. 
LTE Advanced is a mobile communication standard,
formally submitted as a candidate 4G system to ITU
International Telecommunications Union in 2009.

It was finalized by 3GPP in March 2011.It is standardized by
the 3rd Generation Partnership Project (3GPP) as a major
enhancement of the Long Term Evolution (LTE) standard.

17. 
Call forwarding, or call diversion, is a
telephony feature of some telephone switching
systems which redirects a telephone call to
another destination.
