Addressing the Challenge of Aging TDM Infrastructure: A Grant County PUD and Avista Utilities Panel

Tuesday, June 17, 2025
2:00 PM - 3:00 PM PT
Location: CC - 202 C
Abstract Description: Avista Utilities (Avista) and Grant County PUD (GCPUD), like many utilities, operate networks with legacy time-division multiplexing (TDM) products, such as SONET, distribution automation controllers (DACs), and channel banks. These aging systems are either already at the end of their life cycle or will be soon. As part of our evaluation process, we’ve explored various options for replacing this legacy equipment. In this presentation, we’ll delve into the reasons behind our companies’ decision to adopt a multiplexer platform, capable of supporting both SONET and Ethernet transport options. We’ll examine the results of lab testing and evaluate the performance of this multiplexer. Lastly, we’ll discuss the differences in the planned deployments between GCPUD and Avista.
