Ultra OC-3 / STM-1 (PCI) Analyzer

The Ultra OC-3 / STM-1 Card (PCI) plugs into a PC expansion slot for analyzing, testing, simulating, and monitoring OC-3 / STM-1 and STS-1/STM-0 signals. The card can add and drop T1, E1, T3, STS-1/STM-0 signals to and from an OC-3 / STM-1 signal or T1 and E1 signals to and from an STS-1/STM-0 signal. The card can also generate BERT patterns, internally in all framing modes.

Accompanying Windows NT/2000/XP software affords easy operation. SONET/SDH Alarm generation, Error injection and detection capability, overhead monitoring features and its full compatibility with GL's T1, E1 and T3 test products, makes GL's Ultra OC-3 / STM-1 Analyzer a complete SONET and SDH testing solution.

Flexible Solution

Use multiple OC-3 / STM-1 cards in the same PC controlled by the same software, or distribute the cards in different PCs, thereby providing the most flexible solution for your unique testing needs. Add more cards inexpensively, as your testing needs increase.

Features

    User Interface Features
  • Intuitive and easy to use point and click Graphical User Interface
  • Integrated help system that will guide you through every step of the way.
  • Unique multi card feature will allow you to control upto 10 cards from the same software. Once a single card is configured properly, you can copy that configuration to all the cards in the system by a single click.
  • Auto Configuration (Smart Test): Using this feature, the user can connect an OC-3 / STM-1 signal into the receiver of the card. And the software can then analyze the signal structure and tell the user what the signal is comprised of. User can also configure the card automatically, to map to the detected signal type. GL’s OC-3 / STM-1 Analyzer can detect any signal type that the card can be mapped to.
    System Features
  • Internally generate BERT patterns in all framing modes and perform stress test and performance analysis.
  • Add/Drop T1, E1, T3, STS-1, STM-0 to/from OC-3, STM-1
  • SONET/SDH Alarm generation, Error injection and detection.
  • SONET/SDH overhead monitoring, modify/monitor Path Signal Labels, APS and Trace messages.
  • Transmit user-selected T1 (or E1) while remaining T1s (or E1s) are looped back or broadcast.
  • Transmit user-selected STS-1 or STM-0 within OC-3 or STM-1, while remaining STS-1s or STM-0s are broadcast or looped back
  • Internal, External, and Recovered clock sources.
  • Fully compatible with GL's Ultra T1, Ultra E1 and Ultra T3 analysis products.

Field Applications

  • Verify point to point transmission on SONET and SDH circuits.
  • As an Add Drop Multiplexer (ADM) to selectively insert and drop PDH (T1, E1 or T3) signals from OC-3 / STM-1, STS-1/STM-0 signal streams.
  • Troubleshoot network routing and switching by generating and monitoring trace messages with 16 and 64 bytes sequences (J0, J1 and J2 bytes)
  • Generate and detect SONET/SDH and PDH specific alarms and errors.
  • Monitor Pointer Value changes to verify pointer activity which can be caused by timing differences in the network.
  • Monitor and Decode SONET and SDH overhead bytes. Path Trace Messages, APS signaling bytes (K1 and K2), S1 byte with synchronization status messages and Byte Signal Labels (C2 or V5) can be decoded as per ITU-T / Telcordia recommendations.
  • Log alarms and errors on a network over an extended period of time.

OC-3 / STM-1 Analyzer Client-Server Software

Scripting enhancement to GL's OC-3 / STM-1 Analyzer was added to provide, automation and remoting capabilities to the OC-3 / STM-1 analysis platform. The client-server framework provides a flexible and extensible solution for the varied testing needs of our customers. This enhancement will enable - in addition to providing the capability for automation and remoting - the development of customized automation clients through API level integration.

OC-3 / STM-1 Server (OC3Server.exe) is the application that allows you to control a GL Communications' OC-3 / STM-1 Analyzer test set via TCP/IP. It runs under Microsoft WindowsÒ NT, 2000, and XP.

GL Client is a Windows-based application that is distributed with OC-3 / STM-1 Server as a sample client application. It runs under Microsoft WindowsÒ 95, 98, NT, 2000, and XP.

OC-3 / STM-1 Analyzer Client-Server - Main features
  • Allows you to control GL's OC-3 / STM-1 card either locally or remotely.
  • Automation through scripting.
  • Uses the same intelligent parsing and messaging system used by GL's T1/E1 client-server.
  • Can control multiple OC-3 / STM-1 cards using the same command.
  • The wild card and sequential operators available in the command syntax, allows you to configure and control multiple elements of the test set using a fewer lines of commands.
  • Free client software (with source code) is available for download.
  • Custom TCP/IP clients could be developed in any programming language to seamlessly integrate into your existing testing program.

Optical Connectors

The optical interface provided by GL's Ultra OC-3 / STM-1 Analysis card is an SC connector. If your network equipments use connectors other than SC connectors, you can use a variety of Hybrid adapters or Hybrid connector cables (Patch cables) to achieve interconnectivity between GL's Ultra OC-3 / STM-1 card and your equipment.

A list of common types of adapters and connectors are given below. Some of the adapters could be bought as an optional accessory from GL.

Related Terminologies

Polishing: The finish of the connector's end-face determines the quality of its optical transmission. To assure maximum amount of transmission with the least amount of interference, different polishing schemes are in place.

Polishing Types Description Application
Flat Polishing A flat polish of the end-face results in back reflection of about -14 dB(4%) Applications where 4% reflection is acceptable
PC Polishing Physical Contact Polishing - Produces a slightly curved end-face that forces the fibers in the mating connectors into contact. This reduces back reflection to about -40 dB. Most commonly used
SPC Polishing Super Physical Contact Polishing For systems up to 2.5Gb/s transmit capacity
UPC Polishing Ultra Physical Contact Polishing Digital systems > 2.5Gb/s
APC Polishing Angled Physical Contact Polishing Adds an 8 degree angle to a flat polish of the end-face, to reduce the back reflection significantly
