Re-Writes The Business Case For Providing DSL In
Previously Uneconomic Areas!
Telcos are unable to provide DSL to as many
as 30% of their subscribers
Telcos usually find it uneconomic to provide around 10% to 30% of their subscribers with DSL
. Research shows that three problems
must be solved before DSL can be economically provided
everywhere – “Granularity”, “Reach”, and “Broadband
Blockers”.
expandsl is the
only solution to all three of these problems
Most importantly, the innovative product architecture
solves these problems at a break-through cost per
subscriber.
Solution
1: Granularity
In areas where there
is low or uncertain demand for DSL, it may
not be economical to install a traditional DSLAM.
Even a 24-port DSLAM may represent a relatively large initial investment.
To complicate things further, some cabinets
may be so full that there is not enough space for even a "pizza-box" DSLAM.
expandsl solves this ‘Granularity’
problem with very small fully self-contained
DSLAMs that fit into the tightest of spaces.
The low cost of these DSLAMs turns
the business case positive for many remote
cabinets and small Central Office locations.
Profit generated from the first unit
can then be used to fund further growth. |

2: Reach
Since the higher frequencies
utilized by DSL do not reach as far as voice,
some customers can receive telephone service,
but not DSL.
expandsl solves ‘reach’ with
the world’s only fully waterproof and environmentally
hardened DSLAM, utilizing existing copper
plant for line-powering and backhaul. With
this unique architecture, ADSL starts several
kilometres/miles further out in the network,
being backhauled over SHDSL to the closest
cabinet or Central Office.
With the cost of all equipment being shared
across up to eight subscribers, expandsl
solves ‘reach’ more economically than any
alternative. |

3:
Broadband Blockers
Some subscribers may
be ‘blocked’ from DSL, because they are connected
through loading coils or narrow-band pair-gain
systems. In either case, removing these broadband
blockers can be expensive and time
consuming.
expandsl solves ‘broadband blockers’,
by co-locating the line-powered remote DSLAM
with the broadband blocker. Subscriber lines
are connected directly to the remote DSLAM,
which splits out the voice, routing it over
the existing POTS infrastructure. Data from
up to eight subscribers is then backhauled
over unloaded copper. As few as one unloaded
line need be available for the SHDSL backhaul,
saving the expense of unblocking all lines. |
