See The Data Behind AT&T, Verizon, and Other Carriers Turndowns

Major carriers across the globe are executing their TDM turndown strategies at varying paces, creating a complex landscape for enterprises and service providers to navigate. This comprehensive overview examines why do it, announced timelines, completed migrations, and lessons learned from carrier implementations worldwide.

Infrastructure Support Challenges

According to Rob Jodrie, Director of Technical Support at Syncworks, network operators face mounting pressure to migrate from TDM due to critical support challenges:

Legacy Equipment Management

“Much of the TDM network is comprised of systems that were manufacturer discontinued (MD) years ago,” explains Jodrie. “Operators are forced to procure parts from the ‘gray market’ in an attempt to keep this equipment limping along.”

Additional Key Concerns Include:

• Discontinued equipment with limited replacement parts
• Unreliable gray market components at premium prices
• Excessive power consumption compared to modern systems
• Limited alarm surveillance capabilities
• Critical services dependencies (E-911, SS7 call processing)

This industry insight directly aligns with the following carrier migration timelines. Aging infrastructure increasingly impacts network reliability and operational costs. These negative draws will continue to deepen with time.
