The Project - Replacement of PSTN and leased lines

Many utility sites in the UK rely upon PSTN and leased lines to communicate to the central SCADA system.  These lines are prone to relatively high levels of failure, and it is often hard to identify exactly where the fault has occurred.  These lines are prohibitively expensive to install, especially in remote locations where utility sites are often found, and leased lines are very expensive to rent.

Mobile communications that save money

Northern Gas Networks had a number of sites which were using leased lines.  By replacing the existing telemetry equipment with DB1 RTUs operating over GPRS, they were able to remove the leased lines.  The savings made on no longer having to rent the line paid for the equipment and installation costs of the new system within two years.
