Newsletter: GL Announces
Comprehensive IP Analysis and Simulation Tools
Welcome to another February 2016 issue of GL Communications' Newsletter providing information and insight into our industry leading IP Analysis & Simulation tools.
IP and Voice over IP (VoIP) technology has revolutionized the IT and Telecom industries offering significant benefits to both, to name just a few: convergence of voice, video, and data networks, cost advantages in implementation and operation, simplified network management, and opportunities for wide array of next generation network applications . Of course conventional services of voice, video, and data must retain or exceed the quality of legacy networks. GL Communications Inc offers IP and VoIP test suites that addresses wide ranging issues to ensure the performance of IP and VoIP technology.
GL’s IP Test Suite consists of IP, VoIP, Wireless, LAN and WAN Emulation and Analysis tools that are briefly discussed below:

Message Automation & Protocol Simulation (MAPS™) - GL's MAPS™ is a protocol simulation and conformance test tool that can be applied to a variety of protocols such as SIP, MEGACO, MGCP, SS7, SIGTRAN, ISDN, GSM, UMTS,LTE, IMS and others. It also supports simulation of FAX over IP (FoIP) - both RTP G.711 Pass Through Fax Simulation and T.38 Fax Simulation over UDPTL.
TDM/VoIP Gateway Tester - MAPS™ is an ideal tool to evaluate Gateway / ATA with TDM and VoIP Interfaces. The tester supports T1 E1 PRI ISDN, Megaco, and SIP interfaces.
PacketGen™ - It’s a PC-based real-time VoIP bulk call generator for stress testing and precise analysis of the VoIP network equipment. It is based on a distributed architecture, wherein SIP and RTP software cores can be modularly stacked in one or many PCs to create a scalable high capacity test system.
RTP ToolBox™ - This testing and simulation tool is designed not only to monitor RTP and RTCP packets, but also to allow users to manually create and terminate RTP sessions, independent of call-signaling protocols such as SIP, H323, MEGACO, or MGCP.
RTP Traffic Generator - GL’s RTP Core allows creating, managing and deleting RTP sessions. RTP Core is a standalone application that acts as an interface between RTP dll and the application.
High Volume Mobile Data Traffic Generation - GTP Traffic Simulation modules within MAPS™ supports user-plane traffic simulation in LTE, UMTS, and GPRS networks. GTP, or GPRS Tunnelling Protocol are the methods for sending IP traffic in Wireless Networks such as GPRS, UMTS, and LTE.
Testing ATAs & Gateways - GL provides several tools to thoroughly test VoIP ATAs: PacketGen™, PacketScan™, RTP Toolbox™ are to name a few. The Analog Telephone Adapter (ATA) permits consumers to easily utilize the broadband services for VoIP with a conventional landline.
Echo Canceller Compliance Testing - GL has developed powerful tools to characterize echo, noise, and speech characteristics of voice connections. These tools are applicable whether the underlying network technology is PSTN, VoIP, ATM, Wireless, or Satellite.
VoIP ATA’s Testing - The VoIP phones and ATA's must be free of noise and other hindrances that may cause a degraded voice quality when using this equipment. GL's VQuad™ w/ FXO Analog option and/or VoIP option, along with Voice Quality Testing (VQT), provides the complete automated network testing solution including four analog 2-wire interfaces (RJ-11), up to eight SIP User Agents and the voice quality measurement and analysis tools.
IP SoftPhone Testing - GL's Voice Quality Testing (VQT), accessed through an easy to use GUI interface, along with the many supported platforms for transporting voice, provides the voice quality measurement and analysis tools for all types of networks carrying voice traffic.
DCOSS Media Gateway - The system supports dual redundant Ethernet trunks for traffic and signaling testing of VoIP and IP networks. The DCOSS / MG combination provides user-friendly bulk call generation and reception for various voice-band traffic types including voice, fax, and modem.
IP Analysis Tools
PacketScan™ -It’s an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP (version 4 and 6). GL’s PacketScan™ HD for High Density IP Traffic Analysis w/ 4x1GigE Network Monitoring and PacketScan™ FB - a File Based IP Traffic Analyzer Server for near real-time processing of traces. GL’s PacketScan™-All IP Protocol Analyzer supports monitoring all 2G, 3G and 4G protocols such as GSM, GPRS, UMTS, SIGTRAN, LTE, and Diameter, in addition to IP protocols such as SIP, MGCP, MEGACO, Skinny, and H.323.
Packet Data Analysis (PDA) - It’s an outstanding tool for live monitoring of signaling and traffic over IP.
NetSurveyorWeb™ - The tool remotely works with PacketScan™, a central web server and database to facilitate result display using web based clients.
Voice-Band Analyzer (VBA) - The Near Real-time Voice-band Analyzer (VBA) is an analysis tool for monitoring voice band network traffic. The VBA can host different analysis modules for monitoring speech and noise levels, and line echo.
GLInsight™ - GLInsight™ with FAX for IP (FoIP) is a powerful and feature rich offline software tool that analyzes pre-recorded IP fax calls.
VoIP Voice Quality Testing (VQT) - GL’s mobile test solution provides the capability of connecting to and between any network, any service, and any interfacefortesting voice and data quality.
LAN and WAN Emulators
Conducting tests on real WAN links is expensive or simply not feasible in most cases. GL’s WAN Emulators help user to test the performance of such WAN network-dependent applications by emulating the WAN conditions in a local setup easily and cost effectively. GL’s WAN Emulator products are briefly explained below:
GL offers simple-to-use IP Wide Area Network (WAN) link simulator in 2 variants:
- IPLinkSim™ 1 Gbps - emulate a bidirectional IP WAN link with varying capacities from 10 Mbps to 1 Gbps
- IPLinkSim™ 10 Gbps & 1 Gbps - simulate a single bi-directional link between two active ports on both 1 Gbps Electrical/Optical ports and 10 Gbps Optical only ports
IPLinkSim™ is an optional application with portable hardware based PacketExpert™- Ethernet / IP Tester. IPLinkSim™ simulates IP WAN links. WAN Link Emulation is provided essentially by bandwidth control within IPLinkSim™, which mimics slower WAN links like RS232/DSL/Modem/T1/E1/T3/E3 etc.
IPNetSim™ (1G and 10G) - IPNetSim™ emulates an IP network with access to 10 Gbps full duplex link or a 10/100/1000 Mbps full duplex link. For each direction, incoming traffic can be identified into separate user defined streams (up to 16 streams for 1 Gbps pipe and up to 4 streams for 10 Gbps pipe). These user defined streams can be modified to simulate network impairments like bandwidth, latency, packet loss, packet reordering, packet duplication and logic error insertion.
IPNetSim™ 1G/10G Tablet Inspired Portable Unit - The tool is a hand-held battery operated instrument that can simulate the real-time IP and Carrier Ethernet network dynamics by means of hardware controlled packet delay, loss, jitter, errors, bandwidth limitations, congestion, and duplication.
