PoS Protocol Analyzer
for OC-3 / STM-1 & OC-12 / STM-4 - LightSpeed1000™ (Legacy)

The PoS Analyzer captures a host of PoS protocols exchanged between the two nodes over SONET & provides useful analysis, which includes distribution of protocols, protocol fields, frame lengths, and frame status. User can obtain detailed analysis of the protocol and can perform various statistics measurements.

PoS Analyzer supports Packet Data Analysis (PDA) module, it 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.

Analysis of PoS frames over OC-3 / STM-1 OC-12 / STM-4 lines

The PoS analyzer application is invoked from the main menu of GL's OC-3 / STM-1 OC-12 / STM-4 Analyzer for real-time analysis. The analyzer displays Summary, Detail, Statistics, and Hex Dump Views in different panes. The Summary pane displays Dev#, Frame #, Time relative, Len, Error, Layer 3 protocol, LCP code, IPCP code, BCP code, PoS Message type, Source/Destination IP address, TCP Source/Destination Port, UDP Source/Destination Port, Message Type, and so on. The User can select a frame in Summary View to analyze and decode each frame in the Detail View. The Hex Dump View displays the frame information in HEX and ASCII format.

Protocol Summary, Detail, and Hex Dump Views in PoS Protocol Analysis

Multiple ports can be selected for a single instance of analyzer to capture the frames simultaneously. The recorded trace file can then be analyzed offline and exported to ASCII file, or printed.

The real-time capturing requires users to specify ports and Frame Check Sequence (FCS).

Port Selection for Real-time Capture

Statistics is an important feature available in PoS analyzer and can be obtained for all frames both in real-time as well as offline mode. Various statistics can be obtained to study the performance and trend in the PoS network and it is based on protocol fields and different parameters.

Statistics Options for PoS Protocol Analysis

Users can control the captured trace files by saving the trace using different conventions such as trace files with user-defined prefixes, trace file with date-time prefixes, and slider control to indicate the total number of files, file size, frame count, or time limit. This feature also allows the captured frames to be saved into a trace file based on the filtering criteria set using display filter feature.
