Turndown Time
The telecommunications industry is undergoing a massive TDM turndown as carriers worldwide phase out their Time Division Multiplexing (TDM) networks, forcing enterprises to navigate complex migration decisions. While technical teams grapple with implementation details, business leaders must understand the financial implications, operational impacts, and strategic opportunities this transition presents.
Turndown for What?
Enterprise Success Story: Verizon’s Large-Scale Migration
Verizon’s ambitious migration project successfully transitioned over 150,000 business customers from TDM to IP-based services across six states in 2022. “The TDM turndown wasn’t just about upgrading technology – it was about fundamentally rethinking how we serve our enterprise customers,” says Mark Thompson, Verizon’s Senior Director of Network Transformation. “We discovered that nearly 40% of our business customers were running critical security and monitoring systems on legacy TDM circuits they’d forgotten about.”
Healthcare Sector Impact Analysis
Memorial Healthcare System’s migration demonstrates the unique challenges faced by healthcare organizations. “Our initial audit revealed 237 TDM circuits supporting everything from elevator phones to critical patient monitoring systems,” notes Sarah Chen, Memorial’s CTO. The migration required:
- $2.3M initial investment
- 18-month phased implementation
- 99.999% uptime maintenance throughout transition
- Zero impact on patient care systems
Financial Services Case Study
Goldman Sachs completed their TDM migration in 2023, revealing key insights for the financial sector:
- 47% reduction in annual telecommunications costs
- 3-month ROI achievement
- Enhanced trading floor capabilities
- Improved disaster recovery options
