Coherent Assists with Energis Expansion
April 30- Coherent Communications Systems has supplied its EC-6000 Series 2 Digital Echo Cancellers to
Energis, a leading UK business telecommunications company. The cancellers operate with a Nortel DMS-300
International Gateway Switch on a number of Energis' recently-announced international routes, including its
new Sprint route to the US, and its new international direct dial (IDD) route to the Netherlands. This latest
order complements Energis' use of Coherent's EC-7000 units, which were implemented on its very first
international route - to Canada.
Energis' recent expansion has required it to extend its national network to a submarine cable station at Land's
End in the UK. It was awarded its International Facilities Licence in December 1996, and subsequently signed
its first European correspondent carrier agreement with the Dutch network operator, PTT Telecom - also users
of Coherent echo cancellation equipment. The Netherlands route is one of the UK's most active traffic streams,
requiring a high quality service - Bill Buck, Switch Interconnect Manager at Energis explains:
"The EC-6000 Series 2 was a natural choice, offering us a high performance echo canceller product which can
be controlled directly from our Nortel DMS-300 switch. We have been very satisfied with the EC-7000
cancellers and wanted to standardise our cancellation strategy - it is likely that we will implement Coherent
units on all of our international routes in the future."
Energis is a wholly-owned member of the National Grid Group plc, establishing its 4,100 km SDH network of
fibre optic cables primarily along the National Grid's electricity transmission infrastructure.
Designed to exceed current ITU-T standards, Coherent's products provide a flexible operating platform which
can be tailored for a range of applications and network environments. At their core is a combination of
Coherent's state of the art ASIC devices, and patented Non-Linear Processor (NLP) techniques, as well as fast
and stable convergence (50mS for combined ERL and ERLE of 35dB) - prerequisites for modern network
applications.
The EC-6000 Series 2 Digital Echo Canceller also supports Coherent's range of application-specific software,
enhancing the unit's adaptability for a wide range of problem-solving in different network situations. Software
can be remotely downloaded and upgraded, providing a versatile and cost-effective means of maintaining
maximum operational flexibility. In addition, the unit features local loopback facilities, extensive alarm
reporting and self-test diagnostics, as well as significantly reduced power consumption for improved
performance and reduced heat generation.
