Protocol Analyzers for TDM, IP, and Wireless Networks

Welcome to the latest issue of GL's Newsletter providing insight into our Protocol Analyzers which offers a wide variety of centralized monitoring and testing technologies for TDM, IP, and Wireless networks.

Protocol Analyzer

Overview

GL’s protocol analyzers monitor non-intrusively by tapping the network under test. GL can also provide the network tapping equipment, whether it is for T1 E1 lines, Ethernet, OC-3 or OC-12, etc. The protocol analysis software helps users easily identify and troubleshoot network infrastructure, user endpoints and client applications. GL carries the widest array of protocol analyzers for TDM, Wireless, Optical, and Packet networks. Based on a uniform architecture with identical features and functions, they can be used for a wide variety of tasks, including:

  • Build Call Detail Records (CDR) and calculate statistics on captured calls such as Failed Calls, Successful Calls, Call Drops, etc.
  • Save calls to disk for troubleshooting purposes
  • Capture traffic in the field and save for later offline analysis
  • Centralized monitoring of multiple protocol analyzers. Each protocol analyzer sends data such as CDRs to a central database. The database can be accessed via a convenient web dashboard. (See GL’s Advanced traffic collection and processing)
  • Extensive filtering capability for handling large packet captures and protocol traces. Periodically save traffic based on file size, number of frames, or time criteria
  • Monitor physical layer alarms to troubleshoot signaling problems
  • T1/E1/T3/E3 physical layer protocol analyzers enable SNMP DS-1 DS-3 standard MIB traps to be sent to SNMP management applications

GL's PacketScan™- All IP Protocol Analyzer supports monitoring 5G, 4G IMS, 3G, 2G protocols such as GSM, GPRS, UMTS, SIGTRAN, LTE, and Diameter, in addition to IP protocols such as SIP, MGCP, MEGACO, Skinny, and H.323. It can monitor calls from a central location along with powerful and customizable reporting tools.

Packet Data Analysis (PDA) is an included application with GL’s Packet Analyzers. It allows users to monitor live IP networks including capture, analysis, and reporting of every call-in detail. Supported protocols include SIP, MEGACO, MGCP, H.323, SCCP, RANAP (UMTS IuCS), and GSM A.

PDA can capture IP packets and frames over different transmission lines, including IP, T1, E1, T3, E3, and OC-3/STM-1, OC-12/STM-4. PDA then processes the captured packets, identifies, and segregates calls based on signaling and traffic parameters.
