Reliable communication is the foundation of safe and efficient operations. TLE designs and implements Mission Critical Communication (MCC) systems that ensure secure, redundant, and uninterrupted data exchange across industrial and energy infrastructures.
From pipelines to substations, our MCC platforms support voice, data, and control traffic with guaranteed availability even in harsh environments.
Services ride on a transport layer, which rides on fibre, radio or satellite. Select any block to see how it fits and what standards apply.
Redundancy is designed so that a fibre cut or a failed node does not stop operations. The two common approaches recover on very different timescales.
The amber bar is the protection-switching limit generally required for services such as voice and private line, not a measured result. IEC 62439-3 PRP and HSR give seamless failover with zero recovery time.
A communication network that reaches every site is also a path into every site, so it is built with security controls and watched in operation.
The ISA/IEC 62443 approach groups assets into zones that share security requirements, and controls the communication paths between zones, called conduits.
The series sets requirements for asset owners, product suppliers, integrators and service suppliers, so security is built in by everyone involved.
Securing operational technology means accounting for its performance, reliability and safety requirements, so controls are designed around how the operation runs.
STM-16 SDH backbone linking every station to headquarters, carrying SCADA, CCTV, passenger information and legacy telephony.
Restored 87L differential relay communications over existing E1 and SDH networks using custom C37.94 interfaces, with no new fibre required.
Straight answers on what a Mission Critical Communication network carries, how it survives a failure and how it is secured.
TLE designs and implements Mission Critical Communication (MCC) systems that ensure secure, redundant and uninterrupted data exchange across industrial and energy infrastructures. From pipelines to substations, the platforms support voice, data and control traffic with guaranteed availability even in harsh environments.
Redundant fibre optic and wireless networks, IP/MPLS, SDH and Ethernet-based architectures, VoIP, radio and telemetry solutions, with integration to SCADA and security systems. Services ride on a transport layer, which rides on fibre, radio or satellite.
Redundancy is designed so that a fibre cut or a failed node does not stop operations. Ring protection switching (SDH, MPLS-TP) generally needs to complete in under 50 ms, while Ethernet PRP and HSR (IEC 62439-3) give zero recovery time.
A network that reaches every site is also a path into every site, so it is built with security controls and watched in operation. Assets are grouped into zones that share security requirements, and the communication paths between zones, called conduits, are controlled.
Yes. TLE communication systems integrate with SCADA and security systems, and carry voice, data and control traffic, including telemetry and radio solutions.
Yes. Examples on this page include an STM-16 SDH backbone linking every station of a metro railway to headquarters, carrying SCADA, CCTV, passenger information and legacy telephony, and a power utility teleprotection interface that restored 87L differential relay communications over existing E1 and SDH networks with no new fibre.
