The Scenario
Telephone companies will no longer support audio leased lines starting as early as 2015. This presents an issue for utilities currently operating their RFL™ 9745 equipment with an analog communications interface. In some scenarios, full or fractional T1 leased digital data service lines are available for a nominal monthly fee. Utilities are looking for a path forward that minimizes operational impact, requires little engineering, and assures comparable security & dependability for their protection signalling.
