·Add/Drop T1, E1, T3, STS 1, STM 0 to/from OC 3, STM 1
·SONET/SDH Alarm generation, Error injection and detection.
·SONET/SDH overhead monitoring, modify/monitor Path Signal Labels, APS and Trace messages.
·Transmit user-selected T1 (or E1) while remaining T1s (or E1s) are looped back or broadcast.
·Transmit user-selected STS-1 or STM-0 within OC 3 or STM 1, while remaining STS-1s or STM-0s are broadcast or looped back
·Internal, External, and Recovered clock sources.
·Fully compatible with GL’s Ultra T1, Ultra E1 and Ultra T3 analysis products.
Some of the Field Applications
·Verify point to point transmission on SONET and SDH circuits
·As an Add Drop Multiplexer (ADM) to selectively insert and drop PDH (T1, E1 or T3) signals from OC-3 / STM-1, STS-1/STM-0 signal streams
·Troubleshoot network routing and switching by generating and monitoring trace messages with 16 and 64 bytes sequences (J0, J1 and J2 bytes)
·Generate and detect SONET/SDH and PDH specific alarms and errors
·Monitor Pointer Value changes to verify pointer activity which can be caused by timing differences in the network.
·Monitor and Decode SONET and SDH overhead bytes. Path Trace Messages, APS signaling bytes (K1 and K2), S1 byte with synchronization status messages and Byte Signal Labels (C2 or V5) can be decoded as per ITU-T / Telcordia recommendations.
·Log alarms and errors on a network over an extended period of time.
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, OC-12, STM-1, STM-4, 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, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.
GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. 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 accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE 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 line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.
GL’s wireless 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 characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
