SDH Services

Secure and seamless dedicated leased circuits for carriers and service providers

Through our global network, we provide secure and seamless dedicated leased circuits for carriers and service providers, offering an ideal solution for mission-critical voice or data transmission. The TTSA S.A. SDH solution fully utilizes our highly resilient global network, providing impeccable connectivity solutions across the globe.

IMBS
International Managed Bandwidth Service

IMBS is an end-to-end managed bandwidth service that provides customers with dedicated pure Layer-1 International data bandwidth for various types of real-time and mission-critical applications, including data, voice and video.

IEPL
International Ethernet Private Line

IEPL offers customers dedicated International data connectivity and bandwidth, providing high reliability, minimum transmission delay and network security with universally-trusted International Private Leased Circuits (IPLCs).

SDH
Synchronous Digital Hierarchy

Our SDH solutions originate from the Synchronous Optical Networking (SONET). SDH circuits provide enterprises with reliable and secure transmissions, over their own, dedicated, always-on connection.

SDH offers predicted availability targets up to 99.99 percent error-free seconds per year, to ensure that critical data, voice and multimedia transmissions are always successfully delivered, round the clock, 24/7. Our inherently flexible offered SDH solution, is able to carry multiple applications making it perfectly suitable for:

  • Constructing voice and data backbone networks
  • On-line reservation systems
  • Telephone banking and financial transactions
  • Stock control, inventory and order information
  • Mainframes connectivity for bulk data transfer

SDH is a self-healing fiber optic technology that can re-route information in milliseconds, if transmissions are interrupted. It also enables network configuration and capacity allocation to be fully controlled by software applications. It ensures service continuity, including cases when significant demand in bandwidth are needed, in response to upcoming changes in business models, or in preparation for anticipated surges in network traffic.

By aggregating multiple circuits, a number of lower bandwidth circuits can be served on a single aggregated interface. In addition, multiplexing technique makes it possible to de-multiplexing to many channels depending on the application from the SDH service, enabling our clients to carry data, voice and multimedia communications securely and reliably.
