Network Test, Monitoring, and Surveillance Solutions for TDM, VoIP, & Wireless Networks


Overview

GL provides a variety of solutions for network wide monitoring and surveillance. The solutions consist of:

  • Intrusive and non-intrusive "probes" for TDM, VoIP, and Wireless networks
  • These probes deployed at strategic locations in a network can transmit and collect voice, data, protocol, statistics, and performance information, and relay this information to a central / distributed network management system (NMS)

  • The NMS may be client server based or WEB based system and consists of a database and applications for controlling, collecting, and analyzing the information provided by the various probes

GL's current NMS solutions are:

Voice, Video, and Data Quality Testing and Monitoring System for any network

This system provides real-time voice, video, and data quality measurements across a diverse set of networks. Voice and Video calls are automatically placed between end points; quality is measured and provided for display at an NMS. Voice Quality Testing (VQT) supports international standard voice quality test methods, including,  PESQ, POLQA, MOS (Mean Opinion Score), Round Trip Delay (RTD), Jitter, Clipping, Voice band quality metrics, etc. Video Quality Test Solution provides support for Android, PC and Linux based clients (end points) for active Video Quality Testing. The Data Tests supported includes TCP, UDP, VoIP, Route, HTTP, FTP, DNS,  SMS, Email, PhoneInfo, SIMInfo, and UEInfo. 

The essential elements of this system are:

  • Intrusive Wireless / Wireline / VoIP Nodes - GL's VQuad™, is a low density network probe used for proactive testing of end-to-end voice connections. At each node, VQuad™ establishes calls, and send / receive voice files in real-time in an end-to-end manner. Specific nodal hardware is available for connection to TDM, and wireless phones with automatic call control. Wireline and VoIP nodes can connect to TDM, 2-wire, or VoIP network elements. Received voice (degraded) files are transmitted to a Command Center for analysis.

  • The Command Center controls the "Nodes". It controls, schedules, and analyzes the degraded traffic received by the nodes. Advanced features include real time monitoring, scripting scheduling of tests, , and much more. The Command Center includes a database for storage and retrieval of all quality information. 

  • The system also facilitates result display using a simple web browser application WebViewer™. The results are accessed from database that stores real-time and historic data.  The WebViewer™ is also capable of control nodes, start or stop tests, and change test configuration remotely at client locations world-wide.

Packet Monitoring and Surveillance System

GL's "PacketScan™" Ethernet probes is used to monitor packet flows in real-time within a VoIP network. All major VoIP protocols are supported including SIP, H.323, Megaco, and MGCP. PacketScan™ also performs detailed analysis of voice band streams gathering QOS statistics such as MOS (Mean Opinion Score), total packet count, reordered, duplicate and missing packet counts, gap, jitter, and delay. A central database stores the real-time and historic data. The system also facilitates various views using a web interface.

The essential elements of the Packet and VoIP monitoring system are:

  • "PacketScan™" probe gathers IP packet information in a non-intrusive fashion and forward call detail records (CDRs) and statistics to a central database

  • A central database stores the data collected by the probes

  • NetSurveyorWeb™ facilitates result display using a web interface. With this, one can view real-time data, navigate through records, filter the collected VoIP traffic summary, and graphically analyze the call volume, MOS, call completion, failed calls, completed calls, PDD, and so on through a simple web browser...

For more information please see our system description of VoIP & IP Monitoring system.


Digital T1 / E1 Line Monitoring, Test, and Diagnostic System

GL's T1/E1 Network Monitoring System provides network wide management of T1 and E1 lines including line health, intrusive diagnostics, non-intrusive monitoring, and much more. Maintenance engineers can securely access the network view from literally "anywhere" that Internet access is available. They can also monitor, diagnose, and troubleshoot remotely with simple to use scripts.

Essential elements of the system are:

  • PC based T1 and E1 probes that collect physical and line level status and performance information. The Intrusive and Non-intrusive "probes" for TDM networks are deployed at strategic locations in a network. They can transmit and collect voice, data, protocol, statistics, and performance information. These probes can relay information to a central / distributed Network Management System (NMS). They communicate with the NMS via TCP / IP communication.

  • A "T1 E1 J1 Switch" for non-intrusive monitoring or intrusive diagnostics; the switch is "fail safe" during power disruptions and USB controlled by the PC that houses the probes.

  • The NMS provides an instant overall graphical view of the health of the TDM network with drill down to individual lines; secure access through WEB; remote monitoring and diagnostics to troubleshoot any T1 E1 line; and a central database and applications for controlling, collecting, and analyzing the information provided by the various probes.

For more information please see our system description of Digital T1/E1 Line Monitoring System.


TDM Networks Monitoring and Surveillance System

This system provides a uniform method for monitoring the various protocols and content of SS7, ISDN, GSM, and other protocols over T1 E1, T3 E3, SDH and SONET networks. Intelligent protocol analyzers extract relevant content and supply this to a central NMS for storage, display, and control.

Essential elements of the system are:

  • T1 E1 / T3 E3 / OC-3/12 /STM-1/4 Hardware probes that monitor many protocols, including ISDN, SS7, GSM, UMTS, CDMA, and others, (visit protocol analysis page for list of protocols). These probes can process protocol information at varying levels (intelligent software) to extract information of choice and communicate with the NMS through TCP / IP. Probes can process multiple protocol links with a digital cross connect providing the link aggregation. 

  • NMS features include a central database for historical and near real time data storage, a WebServer for "browser based" access to information. Records are stored into a relational database (Oracle, DB2, Sybase, Microsoft Access….) using ODBC. The web-based client NetSurveyorWeb™ connected to SS7 and ISDN probes through a web server facilitates result display using a web interface.

Wireless Networks Monitoring and Surveillance System

This system provides a uniform method for monitoring the various protocols and content of LTE, VoLTE, UMTS, GSM, GPRS, and CDMA protocols over All-IP, T1 E1, T3 E3, SDH and SONET networks. Intelligent protocol analyzers extract relevant content and supply this to a central NMS for storage, display, and control.

Essential elements of the system are:

  • PacketScan™probe to gather IP packet information in a non-intrusive fashion and forward call detail records (CDRs) and statistics to a central database
  • T1 E1 / T3 E3 / OC-3/12 /STM-1/4 Hardware probes that monitor many protocols, including GSM, UMTS, CDMA, and others, (visit protocol analysis page for list of protocols).

CDR Analysis System to capture, analyze, and measure voice-band quality over VoIP, TDM & Wireless networks

When "problem calls" occur infrequently but often enough, they can negatively affect productivity and efficiency of a thriving business.  GL's CDR Analysis System is designed for capturing all calls and all events (including voice quality) during the call, on any network type such as TDM, IP, or Wireless. Signaling, alarm, and call capture over IP or TDM lines is performed with capturing tools such as PacketScan™ or T1 E1 Call Capture and Analysis.  The system allows one to understand and analyze the captured call detail records, troubleshoot call failures, and provide insight into the overall performance. 

The Real-time Voice-band Analyzer (VBA) used along with CDR is an analysis tool for capturing and monitoring the quality of voice band traffic over VoIP, TDM and wireless networks. VBA instantly detects voice file captures and with appropriately installed modules, performs speech levels, noise levels, line echo, traffic classification, and fax analysis measurements. Other analysis modules such as ITU-T P.561, P.562, P.563, fax and modem analysis, and many others can be hosted as plug-ins.

Below is a list of GL's TDM, Packet, and Wireless non-intrusive capture products:

  • GL's TDM T1 E1 Call Capture and Analysis, or 
  • GL's VoIP PacketScan™ 
  • GL's GSM, UMTS, CDMA, and LTE Call Capture Products
