TTMX Teleprotection Terminal Fast and Secure Teleprotection for Transmission and Distribution Grids
Protecting your critical assets after a fault is crucial to maintaining power system stability and safety. Existing technologies are becoming harder to implement with telephone companies suspending their connection leases.
What's need is a standards-based communications solution that is simple to implement, provides fault protection in harsh operating conditions and provides the reliability needed to address teleprotection, including Direct Transfer Trip, Permissive Transfer Trip, blocking and unblocking applications.

What is TTMX?
TTMX Is a Universal Teleprotection Terminal (TT) Multiplexer (MX) for critical and time sensitive inter-substation communications
GE Lentronics Teleprotection terminal provides:
- Secure and Dependable communications: Built on layers of redundancy and substation hardened to ensure reliable operation within harsh substation environments.
- Flexible and Scalable platform: Single or multiple digital interfaces supporting fiber-optic or Copper connections to microwave systems. Modular and hot-swappable interface units.
- Simplified and Secure: Reuse of field proven 'JungleMUX/TN1U/TN1Ue' SONET/SDH technology offering over 28 years of Teleprotection experience across over 300 utilities world-wide.
- Certified to IEC 60834-1 for assured teleprotection performance.
Additionally, the TTMX provides communication monitoring & management. This allows an operator to assess essential parameters like trips, device health, status of the link, settings, and alarms from a remote location.
