As the internet market continues to explode, the demand
for greater bandwidth and faster connection speeds has
led to the need to provide broadband access to the end
users.

ADSL
Used primarily by residential users who receive a
lot of data but do not send much such as Internet
surfers.
ADSL provides faster speed in a downstream
direction (from the telephone central office to the
customer’s premises) than upstream (from
customer’s premise to the telephone central
office).
HDSL
Provides fixed symmetrical high-speed access
at T1 rate (1.5 Mbps).

BSNL’S BROADBAND ACCESS TECHNOLOGY
BSNL has a world class, multi-gigabit, multi-
protocol, convergent IP infrastructure – The NIB.
BSNL Broadband service provides convergent
services through this backbone network.

Data speed capability depends on the
thickness of wire used in cable network.
Higher the gauge, higher the data carrying
speed.

Data speed deteriorates if copper loop quality
is bad i.e. more joints, loose joints, low
insulation etc.
