Whilst the demands of mobile users continue to grow, the need for high bandwidth – low latency backhaul and better accuracy in time synchronisation become crucial to successful implementation and on-going success.

 

Mobile Operators know that failure to transition from E1/T1 to Carrier Ethernet for mobile backhaul is not an option, yet the complexities of Carrier Ethernet arising from the need to cope with multi-class services mean that testing the Carrier Ethernet infrastructure used for mobile backhaul is equally as complex.

We can help you at every stage of your transition from E1/T1 to Carrier Ethernet mobile backhaul, including:

  • Construction and characterisation of the underlying physical layer

  • RFC 2544 validation and testing of connections for Packet Loss, Latency and Jitter

  • MEF Y.1564 Class of Service testing to validate your mobile backhaul SLA

  • Monitoring of Service Quality before, during and after the 72 hour burn-in test period

  • On-going performance monitoring, troubleshooting and of course, end-user QoE.

 

Timing is everything

Deviations in time synchronisation can often result with unintelligible messages and signals transmitted over long distances can see slippage, or even loss of data, resulting with calls being dropped.

SDH has always ensured that users are adequately synchronised over a TDM network – which provides an end-to-end timing facility. Whilst timing is just as important when using Ethernet for mobile backhaul, by nature, Ethernet does not offer the same synchronisation characteristics as TDM. This can pose a real challenge when planning for the transition between backhaul technologies – and this is where we make things count.

We provide advanced solutions and professional services for timing provision and testing, including: IEEE 1588v2 Precision Time Protocol, synchronous Ethernet, packet delay variation and absolute timing accuracy/timing propagation.
