I've been brought in to a large enterprise to examine a perceived problem regarding the use of ADSL lines throughout and determine whether large reductions in usage (and payments) can be made. There are several challenges here:
1- Determine and document the extent of existing ADSL assets and corporate ownership by department;
2- Understand and document the continuing requirement (or non-requirement) for ADSL technology within the enterprise;
3- Determine whether existing ADSL lines are fit for purpose - in other words, whether they are they being used appropriately or whether the purpose could be served using existing network infrastructure;
4- Determine the vulnerability of corporate ADSL lines from the perspective of intrusion and or insertion of malware;
To start I have been given a phone company-provided spreadsheet with over 500 of our corporate ADSL PSTN line numbers, associated and relevant account numbers, an address showing physical location and a billing reference number. Each of the ADSL lines on our enormous monthly/quarterly bills have a standing monthly charge but no additional usage fees as the voice lines do. This means the billing data is of limited use (is that true?) in determining whether the lines continue to be used or have been essentially abandoned after its associated project was accomplished or ceased. I'm asking the telephone service provider if they have individual line usage profiles but I am not optimistic on that request being fulfilled.
FYI - Corporate goals are to reduce 10% of ADSL lines in 1st year, 30% in 2nd year and up to 60% in 3rd year and realizing savings of up to $3M over a ten year period.
Anyone's comments with similar experience in executing this kind of task would be very welcome.
