Teligent Legacy System Integration

Extend the life of existing IT and Telecommunications systems whilst connecting to the latest technologies and protocols.


Modern Telecommunication Providers face the dilemma of maintaining a rich variety of platforms while at the same time looking to reduce costs, implement new technology and EOL extension of key systems where the original provider is no longer supporting these. This leads to the requirement to either replace whole BSS / OSS systems, run parallel systems, or make new systems backward compatible. With the new telecoms world heading for an IP based solution, operators with TDM, BICC or other legacy protocols encounter barriers to achieve interconnectivity and better operational management whilst incrementally pursuing the bottom line cost savings that IP has promised. This is where Teligent's legacy system integration application modernisation capabilities can help!

Cost savings can therefore be achieved by consolidating to a single multi-application platform, eliminating the need for 'parallel running', or by migrating old platforms to lower footprint, higher density modern systems architectures, reclaiming space, power and updating security and resilience.

With part of the Teligent group operating for over twenty years, our vast heritage of experience in systems integration and supply for some of the most demanding applications in infrastructure systems has enabled us to specialise in custom multiple protocol complex system design and service modernisation. Teligent can provide custom solutions to replace legacy systems or simplifying integration problems based on this approach, using its multi-protocol P90/E Platform and wide ranging skills in signaling integration, application development and 24x7 support.
