Overview
GL’s LightSpeed 1000™ analyzer supports ATM interfaces on both the ports and can be configured for
either OC3 or OC12 rate. Multiple cards can be installed in a PC making it scalable to monitor or generate OC3 or
OC12 traffic on multiple ports. Each port on a card can work independent of others, which extends analyzer’s
flexibility as test equipment.
The LightSpeed 1000™ complies with ITU-T ATM standards. The ATM layer architecture and ATM cell
structure in UNI and NNI formats are shown below:

- Emulation and analysis modes are supported on UNI or NNI per port.
- Wire speed cell generation and processing on single or multiple ports using FPGA logic.
- Capture unlimited data to file on individual ports, limited only by hard disk size.
- ATM Tx/Rx application – Supports ATM traffic generation and cell analysis.
- Ability to configure ATM headers (GFC, VPI, VCI, PT, and CLP fields), and bandwidth during traffic generation.
- Rx cell analysis reports Resync count errors and Sequence errors.
- Multistage loopback - Supports Rx-to-Tx memory loopback, line loopback and diagnostic loopback options.
- Ability to capture real-time traffic and playback the traffic for simulation.
- Captures the traffic to files in raw format.
- ATM and UMTS protocol analysis supported on single or multiple ports
- Supports both AAL2 and AAL5 decoding.
- Bit Error Rate Tester application – Supports generation and analysis of payloads at wire speed. Supports
many PRBS patterns and user-defined patterns as payload. Report on error count, error rate, sync loss, SES,
and others are also provided.
- Received cells time stamping to the accuracy of 10ns.
- SONET level statistics for both Tx and Rx cells. Additional statistics for errors, alarms, and BERT test cells.
- Monitor and configure section, line, and path overhead bytes.
Alarms and Error Monitoring
The alarms and error monitoring window provided for each of the OC3/12 port displays detail status of the
communication with the other end. Error logging capability saves all alarm conditions to a file for later diagnosis.
Hardware LEDs are provided on the card to read line alarms. User-defined hardware LED can be programmed as
demanded.
Conditions monitored include –
- Line errors such as OOF, LOS, LOF, AIS, RDI, and APSBF
- Line frequency, power level, and FEAC parameters
- Line, Path, and Section error counts

OC-3/12 ATM Analyzer Applications
Following applications are supported in OC3/12 and STM1/4 analyzer –
ATM Tx/Rx Test
This application is used to generate and/or analyze ATM test cells on the receive side. The selected port can transmit
ATM cells with user-configured ATM header bytes, bandwidth, and interface type (UNI/NNI). Sequence error can be
inserted in the generated ATM cells using “Insert Error” feature. The transmitted test cells can be analyzed at
receive end to check for Resync error counts and Cell sequence loss.
ATM Tx/Rx Test
ATM BERT
This application permits BER test to run as ATM payload.
- User-defined header configuration supported.
- User-defined traffic rate to the accuracy of 0.001% of total bandwidth.
- Payload configuration to different PRBS patterns or user defined pattern. User defined pattern length can
be 2 to 32 bits in length.
- User definable pre-sync achieve window, sync loss bits window, and sync loss declare window.
- Supports sequence number insertion, inverting payload data, single bit error insertion, and error rate insertion.
- Provides detail statistics such as Rx/Tx cell count, idle cell count, bit error count, HEC error count.
- Provides throughput details, error and alarm LEDs for easy analysis.
Protocol Analysis
The ATM protocol analysis is used to capture ATM traffic and provide complete analysis of the protocol
headers and reassembled PDUs along with call detail records. The application supports filtering, statistics, remote
connection via TCP/IP and many more functions.

The UMTS protocol 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. It provides a complete analysis of the
protocol headers and reassembled PDUs in a user friendly GUI. The application supports filtering, statistics, remote
connection via TCP/IP, and many more functions.

ATM Record / Playback
This software allows user to transmit and / or capture packets / cells from / to a file. Files of any length
can be transmitted and captured continuously (without loss) over SONET interface. The analyzer can capture
(record) the received packets into a DAT file. It can also transmit (playback) already captured file (by Receive
Packets to File module) over SONET interface.
These applications are explained in detail below.
Transmit Cells (Packets) from File
This application permits transmission of ATM packets / cells over SONET interface. Users can specify the
transmission limit by selecting different options. The file can be transmitted on the selected port continuously,
for limited number of cells/packets or till the end of file is reached (EOF). Tx bandwidth can be controlled by
specifying the data rate in packets/sec. The GUI displays the statistics of the transmitted packets (or cells)
per second.
Features
- Transmits packets / cells
- Packets / cells can be transmitted either continuously or till the end-of-file (EOF)
- Transmits packets/cells at user configurable rate
- Swap port option can be used to send data on selected ports
- Provides the statistics of the transmitted cells at both line level and payload level
Playback Packets from File
Receive Packets to File
This application permits continuous or limited capture of packets on the SONET interface and saves to a file.
Files of any length can be captured continuously (till user manually stops the capture) over SONET interface and
are limited only by a hard drive size.
Features
- Captures the received packets and saves into a SCF file
- Packets can be captured continuously or limited by a specified size or packet count
