Packet over SONET / SDH (PoS)

PoS, or Packet over SONET / SDH - OC-3/ STM-1 and OC-12 / STM-4 is supported at full rates. Access, capture, analysis, and emulation of PPP and HDLC, all carrying IP traffic in real-time makes this card useful to many applications including Routing, Deep Packet Inspection, and other Internet traffic applications. Current PoS applications include:

• PoS Protocol Analysis PPP Analyzer can be used to capture a host of PPP protocols exchanged between the two nodes over SONET/SDH link. User can obtain detailed analysis of higher later protocols (IP, TCP, UDP, HTTP, FTP, POP3 etc) and can perform various statistics measurements. Integrated Packet Data Analysis feature in Real-time PPP Analyzer is an outstanding tool for live monitoring of VoIP traffic. It can segregate IP traffic into SIP / H323 / Megaco / MGCP calls and collects statistics, CDRs, detailed protocol traces, ladder diagrams, and a host of other useful information about VoIP calls. For more information, refer to Packet Data Analysis in MLPPP webpage for more details.
  
  
• PoS Tx / Rx Test - This application is an emulation and test tool that transmits fixed, random, or variable lengths test packets and checks packets on receive at a user specified data transmission rate.
  
  
• Wirespeed capture of PoS packets to hard disk on both ports simultaneously; with filtering and time stamping of packets. All packets are captured into GL''s file format for further processing. Offline utility can convert it into GL's HDL file format or PCAP format. User can also develop application to process the captured file.
  
  
• Multiple Versatile filters (ex PPP, IP, UDP etc) can be applied to incoming traffic to allow only traffic of interest.
  
  
• Transmit Packets from File - Allows to playback already captured data file to recreate traffic in controlled environment. Also user created traffic file can be played back to generate user traffic.
  
  
• PoS BERT - supports the following PRBS Patterns: 2⁹- 1, 2¹¹- 1, 2¹⁵-1, 2²⁰- 1, 2²³- 1, 2²⁹- 1, 2³¹- 1, all one's, all zero's, alternate ones and zeros, user-defined pattern of lengths from 2 to 32 bits, invert and non-invert selections, single bit error insertion, error insert rate from 10^-1 to 10^-9, status for pattern sync, bit error counters, packet rate and packet gap configuration options, configurable header lengths and header information
  
  
• Alarms and error (section, path, and line) monitoring and logging.
  
  
• Network Delay Emulator - The Network Delay Emulator application provides full duplex delay simulation for PoS and ATM based traffic from 1 ms to 500 ms, with incremental delays of 1 ms. The application combines hardware and software based functions to achieve precision and flexibility. It can emulate packet delays that occur over SONET/SDH carrying ATM/PoS traffic

Asynchronous Transfer Mode(ATM)

ATM over SONT/SDH - OC-3/ STM-1 OC-12 / STM-4 is supported at full rates. Access, capture, analysis, and emulation of ATM cells at wire-speed make this interface capability applicable for wide ranging next generation networks. Current ATM applications include

• ATM Protocol Analysis ATM Analyzer is used to analyze and view ATM protocols across the U-plane for both NNI and UNI interface carrying AAL0, AAL2 and AAL5 traffic.
• UMTS Protocol Analysis UMTS analyzer is capable of capturing, decoding and performing various test measurements across various interfaces i.e. Iub, Iur, IuCS and IuPS interfaces of the UMTS network. In addition, it supports ATM as the transport layer. It helps in fault diagnosis and troubleshooting UMTS network.
• ATM Tx / Rx Test - an emulation and test capability that transmits ATM test cells and/or analyzes the received cells at a user specified data transmission rate.
• Wirespeed capture of ATM packets to hard disk on both ports simultaneously; With filtering and time stamping of packets. All packets are captured into GL's file format for further processing. Offline utility can convert it into GL's HDL file format or PCAP format. User can also develop application to process the captured file.
• Multiple Versatile filters (VPI, VCI, User Data etc) can be applied to incoming traffic to allow only traffic of interest.
• Transmit Packets from File -to playback already captured data file to recreate traffic in controlled environment. Also user created traffic file can be played back to generate user traffic.
• ATM BERT - support for industry standard PRBS Patterns: 2⁹- 1, 2¹¹- 1, 2¹⁵- 1, 2²⁰- 1, 2²³- 1, 2²⁹- 1,
  2³¹- 1, all one's, all zero's, alternate ones and zeros, user-defined pattern of lengths from 2 to 32 bits, invert and non-invert selections, single bit error insertion, error insert rate from 10^-1 to 10^-9. HEC error insertion, on receive filtering is provided for idle cells, GFC, VPI, VCI, CL, and PT cells, statistical details for total cells, valid cells, idle cells, filtered cells, and filtered out cells
• Alarms and error (section, path, and line) monitoring and logging
• Network Delay Emulator - The Network Delay Emulator application provides full duplex delay simulation for PoS and ATM based traffic from 1 ms to 500 ms, with incremental delays of 1 ms. The application combines hardware and software based functions to achieve precision and flexibility. It can emulate packet delays that occur over SONET/SDH carrying ATM/PoS traffic.

SONET/SDH RAW (or Transparent) Payload

RAW mode captures or playbacks anything and everything on SONET/SDH. This mode allows capturing/replaying including SONET/SDH Framing and payload. Here payload can be anything, including structured traffic (T1, E1, STS-1, DS3 etc) or unstructured traffic (ATM, PoS, GFP etc). Raw or transparent mode allows direct access to the SONET / SDH payload for BERT, data transmit and receive applications. Current applications include:

• RAW BERT - support for the following PRBS Patterns: 2⁹- 1, 2¹¹- 1, 2¹⁵- 1, 2²⁰- 1, 2²³- 1, 2²⁹- 1, 2³¹- 1, all one's, all zero's, alternate ones and zeros, user-defined pattern of lengths from 2 to 32 bits, invert and non-invert selections, single bit error insertion, error insert rate from 10^-1 to 10^-9, status for pattern sync, and bit errors counters
  
  
• Wirespeed capture of raw data to hard disk on both ports simultaneously. The data is recorded in 64 bytes block with appropriate header.
  
  
• Playback of recorded data from file at wirespeed on one or both ports.
  
  
• Alarms and Error monitoring and logging at SONET/SDH level.
  
  
• Network Delay Emulator - The Network Delay Emulator application provides full duplex delay simulation for PoS and ATM based traffic from 1 ms to 500 ms, with incremental delays of 1 ms. The application combines hardware and software based functions to achieve precision and flexibility. It can emulate packet delays that occur over SONET/SDH carrying ATM/PoS traffic.
