GL Products, Platforms, News and Trends

3rd, Jan 2020

Welcome to our January 2020 issue of GL's Newsletter providing information and insight into our telecom test and measurement solutions.

Overview

GL Communications Inc. is a leading test and measurement equipment manufacturer of WIRELESS, IP, FIBER OPTICS, ANALOG, and TDM products. Our test platforms provide unprecedented visualization, capture, analysis, simulation, and other features without sacrificing portability, convenience, or cost-effectiveness.

We also offer consulting services to design, plan, implement and inspect communications systems including wireless, IP, satellite, fiber optic, digital, and microwave networks.


Voice, Video & Data Quality

GL offers products to measure voice, video and data quality across a wide range of networks including wireless (3G, 4G, VoLTE, WiFi), Analog PSTN, VoIP (including ATA), and mobile radios. Connections can be made to any wireless or wired phones and devices to perform automated call control, send and receive voice, video, and data, perform real-time signal measurements and GPS mapping. GL uses ITU-standard algorithms (POLQA and PESQ) to assess voice quality.



Ethernet/IP Test Solutions (1 Gbps, 2.5 Gbps, 10 Gbps)

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 AMR WB, EVS, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording.

The product line also includes multi-functional Ethernet/IP Testers to test cables, routers, switches, and end-to-end networks. The test tools generate traffic at wirespeed and report statistics such as frame loss, throughput, latency, errors and other impairments. GL’s multi-functional Ethernet/IP testers can also perform RFC 2544, RFC 6349, ITU-T Y.1564, generate network impairments (delay, loss, jitter, errors, bandwidth limitations, packet reordering, and duplication), and can capture, record and playback packets at wirespeed.



Wireless Network Test Solutions(5G, 4G, 3G, 2G, Wi-Fi, Wi-Max, Bluetooth®)

With GL’s Wireless Network Lab, you can test infrastructure for various functions such as calls between two UEs in the same network or different networks, inter-operability between 2G, 3G, 4G and 5G networks, Circuit-Switched fall-back and SMS while roaming, location services, and many more.

GL’s test suite can be used to simulate all or specific elements within wireless networks infrastructure using simple ready-to-use scripts. It allows for functional testing, performance testing, and conformance testing compliant with ITU-T and 3GPP standards. Product capabilities cover all traffic types (Voice, Digits, Tones, Fax, GTP, HTTP, and PCAP).

These test solutions can be used in the lab or in the field with unlimited ability to edit wireless communication protocol messages and control call scenarios.



TDM/PSTN Network Test Solutions (T1 E1, T3 E3, Datacom, 2 Wire FXO, 4 Wire Analog)

GL’s TDM/PSTN Analysis & Emulation line of products include T1, E1, T3, E3, Datacom, Analog 2-wire (Central Office (CO), PBX, ATA, Gateway), 4-wire (Headset, Push to Talk connecting to any mobile radio and to any mobile phone), 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. Tap for non-intrusive monitoring, capture and replay, or perform load testing by simulating high volumes of callers and capture capability up to and including gigabit speeds.

There are several customized products under this category designed to cater to industry-specific requirements. Examples include a complete 911 test solution to validate and test CAMA-type 911 networks, and an echo mitigation system designed to address the audio delay issues resulting from the different backhaul technologies and remote sites.
