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 (intrusive probes)

• Packet/IP Network Monitoring and Surveillance System (passive / non-intrusive probes to capture, analyze, and measure signaling, traffic, and voice-band quality)
• Wireless Network Monitoring and Surveillance System (passive / non-intrusive probes to capture, analyze, and measure signaling, traffic, and voice-band quality)

• SS7, ISDN, Monitoring and Surveillance System (passive / non-intrusive probes to capture, analyze, and measure signaling, traffic, and voice-band quality)
• Digital T1 E1 Line Monitoring, Test, and Diagnostic System

• 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

For more information, refer to Intrusive Voice Quality Test and Monitoring System

• 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, refer to our system description of VoIP & IP Monitoring system.

• 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, refer to our system description of Digital T1 E1 Line Monitoring System.

• 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

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:

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