GL Communications Unveils SonetExpert for Comprehensive SONET/SDH Testing
July 17 2024 - 11:55AM
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. For more
details, visit the SonetExpert™ Channelized (SEC) Analyzer
webpage.
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. For more details, visit the PacketExpert™-
Multi-Functional Ethernet/IP Test Solution webpage.
