The
DSL Problem
The
explosive demand for broadband services has accelerated the
development of access network transmission technologies that
greatly increase the bandwidth available over conventional
wire-line circuits. Incumbent Service Providers (ILECs/
PTTs/ TELCOs) are searching for cost-effective solutions
that help to quickly and accurately assess the xDSL
suitability of their wire-line inventory.
Time-to-market
pressure, stringent Service Level Agreement requirements,
slim product margins and reduced capital equipment budgets
combine to make the situations seemingly untenable.
Given no alternative to huge, budget-draining xDSL
implementation costs, these service providers have been
using their existing records, crude line length
calculations, or manual/spot testing techniques to identify
problematic lines.
The results have
proven to be less than acceptable !

The
Solution
Porta Systems Internet
Services Coverage
ANalysis
(i.Scan)
is a sophisticated
system for evaluating copper wire-line circuits to determine
their suitability for new high-speed digital services.
i.Scan
is the result of innovative research into improved
methods for single ended line qualification and enhanced
modeling of twisted pair performance at high frequencies.
Porta Systems patented algorithms have been
combined with existing best-in-class line test system
technology - based on the Sherlock
MkIII remote test unit - to provide a unique
solution to the need to classify and evaluate the
capabilities of the existing copper network infrastructure.i.Scan
is an essential tool for any network operator or service
provider deploying DSL technology to provide broadband
services.
i.Scan
is a centralized system that accurately pre-qualifies
telephone lines for DSL services. Using a rules based
technology and patented narrow-band measurement techniques
i.Scan can accurately predict the broadband
performance of a single loop or an entire network.
Features:
- Classifies loops for
single or multiple DSL services
- Periodic testing of part
or whole network
- Configurable rules engine
easily tailored to match DSL services offered
- Detects network
impairments that will affect DSL services
- Maintains a database of
qualified loops for on line access by planning,
marketing and sales organizations
Key
Benefits:
- Single-ended qualification
reduces truck rolls and saves the cost and time of field
testing - faster service fulfillment and lower
deployment costs.
- Identifies all viable
services - sell the optimum service and maximize
revenue and customer satisfaction !
- Survey the network - identify
service coverage and make the best use of network
assets, plan network up lift and grooming.
Historically, i.Scan
has been coupled with the Porta Systems Sherlock
MkIII remote test unit for a robust POTS
testing and xDSL qualification solution.
Incumbent Service Providers have now requested an
even more cost-effective solution to xDSL pre-qualification
that can coexist with their ‘legacy’ POTS test system
thus preserving their investment in equipment and staff
training and eliminating the need for additional wired-line
access arrangements.

The
Solution
Porta
Systems has responded with the revolutionary DSLScan
system.
The DSLScan
system is comprised of the proven iScan
controller and S/W and the new xDSL
RTU - a new low-cost, xDSL pre-qualification
specialized test unit designed to coexist with and utilize
the functionality of the existing POTS test system, thus
providing a cost effective solution that does not duplicate
functionality.
The xDSL
RTU satisfies the requirements of DSLScan
(i.e. returns advanced parametric measurements that
culminate in the predicted insertion loss of the line at any
xDSL frequency) using ground breaking proprietary techniques
compatible with voice grade switch test paths. |
