These involved a total of some 18,000 channels of Coherent echo cancellers, operating with Ericsson AXE 10 switches.
The Coherent echo cancelers are used in PTT Telecom's international switching and GSM operations, highlighting the ability of Coherent's echo canceler to provide exceptional performance for both wireline and wireless applications.
The Coherent echo canceller uses patented Non-Linear Processor (NLP) techniques, as well as fast and stable convergence (less than 50ms for combined ERL and ERLE of 35dB) - both prerequisites for modern network applications.

Turk Telekom has recently installed an additional 150 groups of Coherent echo cancellers - 100 groups are for use in its newly-installed international DMS300 switch in Izmir, with 50 to be implemented in its satellite IBS (International Business Services) network for rural area communications.
Commenting on the performance of the Coherent echo cancellers, Group Chief Engineer, Zafer Kucakates said:
It was awarded its International Facilities License 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.
This represents the completion of a major two-stage contract, which involved some 18,000 channels of Coherent echo cancellation in total.
The Coherent Monitoring, Observation, and Response system, or c/mor, makes possible remote monitoring and configuration of Coherent echo cancellers located throughout a customer's network.

As of the end of the third quarter, NORTEL sales personnel have begun selling Coherent echo cancellers, especially in North America.
