Product Description:
Acterna JDSU EST-120 is a multi-purpose field service tester, designed for debugging, maintenance and troubleshooting of E1 PCM circuits. It can perform a variety of tests, including: framed and frameless monitoring, framed and frameless end-to-end testing, discard and insert, channel dependent signaling monitoring, round-trip delay measurement and repeated BERT.
Product Features:
Provide scalable test solutions for E1 and data test applications, supporting a wide range of software options for E1 service (frame relay, GSM) and sub-rate multiplexing system (X.50, HCM, V.110) testing
Allow for quick assessment of circuits through an intuitive user interface with automatic configuration functionality and a clear large result screen
A full set of physical layer tests is adopted for E1 balanced and unbalanced circuits, including BERT, VF, round-trip delay, signal level, pulse shape and jitter
Provide standard options for the Quality of Service (QoS) measurements recommended by ITU-T G.821, G.826 and M.2100
Through the patented Gelbricht synchronization method, bit errors and bit slippage in QoS testing are clearly distinguished
