Harmony Trunk

Long-haul microwave trunking solution

The Harmony Trunk is a hybrid microwave solution with the capability to smoothly migrate from full-TDM, to Hybrid, to full-IP via a simple software configuration.  Operators can transport TDM and IP signals natively over the air without any encapsulation or mapping.  The Harmony trunk’s outage-less expansion and upgrade process ensure a rapid and simple installation and fast network roll-out.  With its advanced features and performance, the Harmony Trunk can significantly enhance existing copper and fibre optic core transport systems.
