Press Release: GL Enhances OC-3/STM-1
Analyzer Hardware & Software

Gaithersburg, Maryland, USA - August 25, 2009 - GL Communications Inc., announced today the release of enhanced OC-3 / STM-1 Analyzer - a feature rich test instrument for testing SONET and SDH signals. In a press note issued, Mr. Vijay Kulkarni, CEO of the company said, “The Ultra OC-3 / STM-1 Card plugs into a PCI PC expansion slot for analyzing, testing, simulating, and monitoring OC-3 / STM-1 and STS-1 / STM-0 signals. The Card can add and drop T1, E1, T3, STS-1/STM-0 and bulk filled signals to and from an OC-3 / STM-1 signal or T1 and E1 signals to and from an STS-1/STM-0 signal. The card can also generate BERT patterns, internally in all framing modes and perform stress test and performance analysis. SDH and SONET alarms can be monitored and logged in real time”.

He added, “Accompanying Windows NT/2000/XP software affords easy operation. SONET/SDH Alarm generation, Error injection and detection capability, overhead monitoring features and its full compatibility with GL's T1, E1 and T3 test products, makes GL's Ultra OC-3 / STM-1 Analyzer a complete SONET and SDH testing solution. It is ideally suited for installation, maintenance, commissioning, verification and manufacturing of SONET/SDH transport networks and network equipments”.

Mr.Kulkarni, further added, “Scripting enhancement to GL's OC-3 / STM-1 Analyzer was added to provide, automation and remoting capabilities to the OC-3 / STM-1 analysis platform. The client-server framework provides a flexible and extensible solution for the varied testing needs of our customers. This enhancement will enable - in addition to providing the capability for automation and remoting - the development of customized automation clients through API level integration. The client-server application helps configuring SDH and SONET parameters, Signal Mapping, Transmit and Receive BERT, Error insertion and verification, Secondary Signal (T1/E1/T3/STS-1), and Alarms setting and retrieving”.

Important features

  • Allows you to control GL's OC-3 / STM-1 card either locally or remotely
  • Automation through scripting
  • Uses the same intelligent parsing and messaging system used by GL's T1/E1 client-server
  • Can control multiple OC-3 / STM-1 cards using the same command
  • The wild card and sequential operators available in the command syntax, allows you to configure and control multiple elements of the test set using a fewer lines of commands
  • Free client software (with source code) is available for download
  • Custom TCP/IP clients could be developed in any programming language to seamlessly integrate into your existing testing program

About GL Communications Inc

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.

GL’s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL’s wirelss VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
