Overview

Most of the backbone transport for voice, video and data applications continues to be SONET and SDH optical transmission networks. SONET and SDH transmission network also continue to be used for conventional channelized traffic – carrying many TDM T1, E1, T3, and E3 pipes.

GL's SonetExpert™ Unchannelized Analyzer is capable of SONET/SDH testing over OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 and OC-192/STM-64 transports. It is based on the PacketExpert™/SonetExpert™ hardware platform. Packetexpert™/SonetExpert™ is a versatile hardware platform that supports both Ethernet (up to 10G) and SONET/SDH (up to OC-192/STM-64) testing, two ports support SONET/SDH testing. Multiple hardware units can be connected to a single PC to increase test port density. The software provides a web interface, and is accessed through any browser running on any device like PC, Laptop, tablet etc. In addition to Raw SONET/SDH, it also supports Packet Over SONET/SDH (PoS) and ATM over SONET/SDH.

GL's OC-3 / STM-1 OC-12 / STM-4 ATM Analyzer is used to analyze and decode different ATM protocols like ATM, AAL2 Protocols (CPS-SDU, SSSAR-SDU, and SSCS), AAL5 (CPCS), UNI and others across U plane and C plane of UNI and NNI interface. The analyzer can also decode ATM frames constituting Classical IP over ATM, or CIP based networks, and traditional SS7 Stack (ISUP, SCCP, MAP, CAMEL(CAP) etc.) over ATM.

GL offers High-Density mTOP™ 1U/2U rack mount enclosures within which multiple SonetExpert™ hardware units are stacked to provide high density form factor solution for testing multiple SONET/SDH lines. It is a perfect SONET/SDH test tool for customers who require multi-port testing but are constrained by lab space.

GL also offers stand-alone mTOP™ Probe hardware variant of SonetExpert™, where a SonetExpert™ hardware unit is coupled with a built in SBC (Single Board Computer), to make it a compact, portable toll, ideal for field testing.


Main Features

  • Bit Error Rate testing (BERT):
    SonetExpert™ can perform Unchannelized BER Testing over OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 and OC-192/STM-64 SONET/SDH rates. It treats the entire OC-3 to OC-192 as a single big pipe and sends/analyzes BERT traffic as a whole for the entire pipe i.e using concatenated STS-3c/STS-12c/STS-48c/STS-192c signals. This helps to test and qualify the entire SONET/SDH pipe as a whole, before delving into smaller pipes carried within. BER testing over Packet Over SONET (PoS) and ATM on OC-3/STM-1 and OC-12/STM-4 is also supported.
  • Alarms/Error Monitoring:
    GL’s SonetExpert™ application monitors and reports various SONET/SDH Alarms (Section/Path/Line as well as BERT Alarms) in real time. Alarms are also plotted in a graph and up to 7 days of alarm data can be viewed in the graph. Alarm generation and Error insertion also supported.
  • Protocol Analysis
    PoS/ATM/Raw captured traffic can be analyzed in real time (for OC-3/STM-1 and OC-12/STM-4). Protocol Analysis provides detailed analysis of higher layer protocols (for PoS and ATM) and decode of SONET/SDH frames in real time on both ports simultaneously.
  • Record and Playback
    SonetExpert™ supports capturing wirespeed traffic (for OC-3/STM-1 and OC-12/STM-4) traffic on two ports simultaneously to a file on hard disk, with hardware filtering and timestamping. The captured traffic can be played back from file on both ports simultaneously. In PoS mode, PPP packets are captured, in ATM mode ATM cells are captured, and in Raw mode, Raw SONET/SDH frames are captured. Similarly for playback, PPP packets/ATM cells/Raw SONET/SDH frames can be played back on both ports simultaneously.
  • Scan incoming SONET/SDH traffic and identify the traffic structure:
    GL’s SonetExpert™ Unchannelized application includes the Scan feature which scans the incoming traffic on SONET/SDH interfaces, identifies and displays the traffic structure. The results of the scan are displayed in an intuitive multi color graphical display, which clearly shows the sub channels within the main pipe. Traffic structure up-to STS-3c is identified and displayed in the main display, with different colors clearly indicating equipped or unequipped channels. On clicking any equipped channel, further details of the subchannel like the sub structure up-to the T1/E1 level is also displayed. This feature gives a complete overview of the incoming SONET/SDH traffic in an easy and intuitive Graphical display and helps technicians to quickly identify the structure of unknown SONET/SDH traffic.
  • Web based software:
    Software is provided as a web interface, accessed from any standard web browser, allowing access from different devices like Pcs/laptops/tablets etc. and from different OS like Windows/Linux/Android etc. Web interface allows multiple users to connect to a single web server and independently run tests on different hardware units Running the web server on the mTOP™ probe unit allows portable field testing by using a tablet running a browser to access the software features.

PoS Analyzer

The PoS analyzer captures a host of PoS protocols exchanged between the two nodes over SONET and 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, an outstanding tool for live monitoring of signaling and traffic over IP. Packet Data Analysis (PDA) is distributed with GL’s Packet Analyzers, 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. PoS 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.

Scan Application

SonetExpert™ scans incoming SONET/SDH traffic, analyzes the frames, detects and reports the structure of the incoming traffic, down to the T1/E1 level. It identifies the various sub pipes within the main pipe, and also the entire structure of each sub pipe right down to the T1/E1 level.

  • Supported on OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 and OC-192/STM-64 rates
  • Graphical display of the traffic structure for easy visualization
  • Identifies and displays sub channels up to STS-1
  • Indicates equipped and unequipped sub channels in different colors for easy identification
  • Shows substructure of each STS-1 pipe, right down to the T1/E1 level
  • User selectable SONET or SDH terminology
  • Supported on both the ports independently

The below screenshot shows result of scanning incoming traffic on OC-192. The scan shows that the OC-192 contains 4 OC-48 pipes within, and shows details of each of the 4 OC-48s in a separate tab. For each OC-48 further shows details of the OC-12s, and in turn details of the OC-3s within the OC-12s, down to the STS-1 level. For each STS-1, shows the details of the traffic structure contained within the STS-1. The equipped channels are clearly marked in Blue so that user can easily make out which channel is equipped with a quick glance.

The STS-1 #1 is equipped channel, which contains VT1.5s within it, as shown. On clicking on the substructure button, the detailed substructure is shown above. It shows 28 VT1.5 channels, and within it, the VT1.5 on Row2, column 3 is equipped as shown in Green.
