GAITHERSBURG, Md., July 17, 2024 (GLOBE NEWSWIRE) — GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their solutions for testing Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) traffic with the SonetExpert platform at speeds up to OC-192/STM-64 networks.

Vijay Kulkarni, CEO of GL Communications, states, “GL’s SonetExpert is capable of SONET/SDH testing up to OC-192/STM-64 networks. With two dedicated ports per hardware unit, multiple units can connect to one PC for increased port density. The hardware control is via a web-based interface accessible from any browser on devices such as PCs, laptops, and tablets. The analyzer supports Bit Error Rate Testing over Raw SONET/SDH testing up to OC-192/STM-64 and various applications such as ATM and PoS for up to OC-12/STM-4 rates.”
SonetExpert can perform BER testing over OC-3/STM-1, OC-12/STM-4, OC-48/STM-16, and OC-192/STM-64 SONET/SDH rates, treating the entire OC-3 to OC-192 as a single large pipe. It transmits and analyzes bit patterns for the entire pipe using concatenated STS-3c, STS-12c, STS-48c, and STS-192c signals, allowing for comprehensive testing and qualification of the entire SONET/SDH pipe before delving into the smaller pipes within. Additionally, it supports BER testing over PoS and ATM payloads up to OC-12/STM-4. The platform monitors and reports various SONET/SDH alarms, including Section, Path, Line, and BERT alarms, in real-time, with alarms plotted on a graph for up to seven days of historical data. It also supports alarm generation, error insertion and hardware indications for Loss of Signal and Frames.
PoS/ATM/Raw captured traffic can be analyzed in real-time providing detailed analysis of higher-layer protocols (for PoS and ATM) and decoding SONET/SDH frames on both ports simultaneously. SonetExpert captures wirespeed traffic on two ports simultaneously to a file on the hard disk, featuring hardware filtering and timestamping. Captured traffic can be played back from a file on both ports simultaneously. In PoS mode, it captures PPP packets; in ATM mode, it captures ATM cells; and in Raw mode, it captures Raw SONET/SDH frames. The playback capabilities allow for PPP packets, ATM cells, or Raw SONET/SDH frames to be played back on a single port or both ports.
SonetExpert analyzes incoming SONET/SDH traffic and displays its structure in an intuitive multicolor graphical interface, highlighting subchannels down to the STS-3 signal. Equipped and unequipped channels are color-coded, and clicking on an equipped channel reveals detailed substructures down to the T1/E1 level, offering a comprehensive overview of the traffic.
In addition to Unchannelized testing, GL also offers the SonetExpert Channelized Analyzer for capturing, monitoring, simulating and analyzing protocols over SONET-SDH links, supporting channelized SONET and SDH mapping of T1/E1 payloads.

GL also provides the PacketExpert 10GX, a high-speed Ethernet and IP test solution on the same hardware platform, featuring wirespeed BERT, RFC 2544/Y.1564/RFC 6349 tests, packet capture, event-driven triggers, traffic playback, impairment generation, and stacked VLAN/MPLS tests.
