Protocol Analysis for Wireless and IP Networks
GSM, GPRS, UMTS, SIGTRAN, LTE, Diameter, & IP Protocols


GL Communications offers a wide range of centralized monitoring and testing technologies for Wireless and IP Networks.

GL's PacketScan™- All IP Protocol Analyzer supports monitoring all 2G, 3G and 4G wireless communication protocols such as GSM, GPRS, UMTS, SIGTRAN, LTE, and Diameter, in addition to IP protocols such as SIP, MGCP, MEGACO, Skinny, and H.323.

PacketScan™ cellular protocol analyzers support analyzing signaling across multiple technologies (Mobile, IMS, LTE, SIGTRAN, VoIP, etc.). Monitor calls progressing through advanced 3G or 4G networks from a central location, along with the powerful and customizable reporting tools.

Packet Data Analysis (PDA) is an outstanding tool for live monitoring of signaling and traffic over IP. Packet Data Analysis (PDA) is distributed with GL’s Packet Analyzers, allowing 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. It can capture IP packets 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.

Common Features

  • Advanced filtering and search based on any user selected protocol fields
  • Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields
  • Trigger intelligent actions based on signaling, and traffic conditions
  • Support for Multi-technology, Multi-protocol
  • Displays Summary, Detail, Hex dump, Statistics, and Call Detail Views.
  • Detailed View
    • Displays decodes of user-selected frames from the Summary View
    • Provides options to display or hide the required protocol layers
    • Contents of this view can also be copied to clipboard.
  • Hex dump View displays the frame information in HEX and ASCII format, the contents of this view can also be copied to clipboard.
  • Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire capture data.
  • Call Detail View displays called/ calling number, released calls, call status, & more.
  • Provides a consolidated interface for all the important settings required in the analyzer. All the configuration settings done in any of these options can be saved to a file, loaded from a configuration file.
  • Allows the captured frames to be saved to a trace file using different conventions such as user-defined prefixes, date-time prefixes, total number of files, file size, frame count, or time limit.
  • Supported on Windows® XP and Windows® 7 (32 bit and 64 bit) OS.
  • Provides scalable, centralized, real time, end-to-end network visibility and trouble-shooting capability
