The CTS850 is a versatile analyzer for Broadband Network Testing. It has a powerful, yet uncomplicated, menu structure which allows both the novice and expert user to accurately configure measurements on SDH and PDH networks very quickly. All measurement connections are conveniently located directly on the front panel close to the signal status LEDs and easy-to-read display.
A field-interchangeable optical module and a floppy disk drive for retrieval of stored setups and results complete the front-panel layout to create a "field-friendly" instrument.
SDH/PDH/Jitter and Wander Testing:
The CTS850 creatively addresses growing concerns surrounding hybrid SDH/PDH networks in the area of timing and synchronization. Its industry-leading, DSP-based, Jitter and Wander measurement capability provides a high 300 UI jitter measurement range, handles all line rates from 2 MBps to 622 MBps through existing front-panel connectors and introduces exclusive new measurements for digital video services.
The CTS850 unlocks the power of the SDH frame structure by combining bit error testing with overhead analysis and payload mapping and demapping. It provides read/write access to overhead bytes, DCC add/drop, and complete G.783 pointer test sequences.
The CTS850 is optimized for installation and maintenance of both current and future SDH networks. Additional functionality, reflecting evolving standards such as new O.172, can be downloaded through the built-in disk drive.
One of the CTS850's many powerful functions is error analysis and display. In addition to simple error counts and rate determination, the CTS850 makes measurements according to G.821, G.826, G.827, and new M.2101.1 performance analysis and M.2100 error analysis so that network quality of service can be fully verified in or out of service.
Histograms boost the power of error analysis by enabling an easy correlation of time-critical events. Thus, time-consuming searches through long strips of error printouts are eliminated, freeing you to spend time fixing problems, not finding the cause.
PDH Testing:
Many networks have evolved from PDH to include SDH rings and long-distance, high-capacity trunks. The PDH network segments are commonly retained for access, service delivery, and economic reasons. The CTS850 Opt. 38, PDH Tributary card provides features for testing and accessing PDH subrates from 140 MBps, 34 MBps, 8 MBps, 2 MBps, down to N/M 64 Kbps. Additional PDH test features also include simultaneous multilayer G.826, M.2100 results, Round Trip Delay, Voice Channel Monitor, and Burst FAS Errors.
This option also empowers the CTS850 with mapping and demapping of 2, 34, and 140 MBps payloads in virtual containers and testing of TU-12, TU-3 and AU-4 overheads, making it ideal for testing hybrid networks.
