The perfect tool for testing SDH & SONET core networks up to 10 Gbps

SDH and SONET technologies are firmly established in the core and metropolitan networks. STM-64 and OC-192 are widely deployed in today’s networks. While great care is devoted to warrant a very high quality of transport, in the real world of dayto-day installation, commissioning and maintenance activities things are not always running smooth. To this effect, several important tests are always carried out in order to assess the good behaviour of these networks before turn-up. Similarly, when the network has been turned on, it is paramount to keep monitoring the network health at physical level and beyond.

The SDH/SONET application of the UTA module provides a complete set of test functions for testing SDH/SONET networks up to 10 Gbps, among which we find the checking & monitoring of the optical levels, alarm, error & frequency stressing, tributary mapping checking, routing, connectivity and pointer tests on the synchronous payloads, round trip delay measurement, BER tests, automatic protection scheme switching time and more.

As a part of the UTA applications family, the SDH/SONET application is just one test solution among many others. The UTA module has been designed to support almost all the transport standards of modern networks (ex: 10 GigE, G.709, …) and represents a new class of tester for the field engineers. One tool is all you need!

Testing APS switch time reaction of the network with 125 µs resolution

Due to the large amount of information being transferred over Synchronous Optical Network (SONET/SDH), it is extremely important to ensure that the transport services are as readily available as possible. APS -Automatic Protection Switching- is the protection mechanism that has been implemented in SDH/SONET networks in order to guarantee the availability of the network in case of problems. The protection process involves switch actions between working fibers and backup fibers. This process is completed when the equipments at both ends of the network have completed these actions within the same 50 ms completion time. The result of this operation is the disappearance of the defaults because the traffic is then transmitted on the backup channel. The UTA-SDH/SONET application is able to detect defaults that may appear during a protection switch and displays their duration with 125 µs resolution. With the ‘’Event Analysis” function of UTA, you have access to all the information from a single window: total switch duration, details of all the events, partial duration for each event…

Auto-discovery of the signal structure

When performing tests in the field, it is sometimes difficult to configure the test equipment as the signal to be analyzed is not always known: is the signal concatenated, what the frame mapping structure is, are the containers of the frame all equipped or partially equipped? In such a situation, configuring the test equipment can be very painful and time consuming.

The “Structure Scan” function of the UTA application brings a smart solution to this type of problem. “Structure Scan” automatically analyzes the signal and displays its frame structure in a graph for fast and easy interpretation. The “Structure Scan” graph can give a complete overview of the frame down to the tributary and allows the automatic configuration of the UTA application.

Fig.2: Discovering the frame structure of an unknown signal is easy with the “Structure Scan” function. Mix-payloads are also supported.

Field exchangeable XFP/SFP transceivers

The UTA module supports hot pluggable XFP/SFP transceivers. This feature brings a lot of configurability to the module. In the field, the user just has to replace the XFP/SFP by another to change the optical interface characteristics. Whatever the SDH/SONET link or equipment to test, the field engineer has the insurance to be able to equip his UTA module with the right optical interface.

Fast and professional reports

Creating professional report has never been so easy with the UTA application. After stopping a measurement, the report is just one click away: produce, save, print reports directly from the application. Select the set of results you want to produce, fill in the header information associated with the measurement and the UTA application will generate professionally presented reports in PDF format.
