How do I convert my RFL 9745 analog
teleprotection equipment to operate over
T1 leased digital lines?
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.
The Solution: For point-to-point teleprotection applications, RFL offers a complete digital DDS upgrade kit that allows
the customer to replace the 9745 analog interface
with a digital interface module set. The RS-449
digital interface cables directly into a Channel
Service Unit / Digital Service Unit, which in turn
plugs directly into a full or fractional T1 line. This

Editor’s Note: In our last newsletter, Dan Belmont brought us up to date on the happenings in the telecommunications industry with the state of wire line carrier services and their bid to retire the old analog services that utilities use for critical communications utilities. To follow up on that initial work, West Monroe Partners launched effort survey of public, private, and cooperative utilities nationwide to better understand the direct impact of this problem. This survey included utilities of all sizes and pinpointed the key parameters of their analog circuit technology in use, public carrier service levels and costs, circuit reliability, carrier interaction, market perceptions, and initiatives in place to remedy this significant change. This article highlights what utilities are doing today to remedy this critical operational communications issue and outlines some potential next steps.
