LightSpeed1000™ Tx Rx Test
(OC-3 / STM-1 and OC-12 / STM-4)
Overview
Tx Rx Test tool in LightSpeed1000™ is an emulation and test module that transmits test packets/cells
and/or analyzes the received packets/cells.
ATM Tx/Rx Test module generates test cells, which can be analyzed at the receiving
end to check for data modifications and cell loss/insertion. Sequence error can be inserted in the generated ATM
cells using the “Insert Error” feature.
POS Tx/Rx Test module provides users the option to send fixed, random, or variable
lengths test packets, and insert user-defined frame header in the packets transmitted.
ATM Tx/Rx Test
This module generates ATM test cells and/or analyzes the received cells. The selected port can transmit ATM cells
with user configured ATM header bytes, bandwidth, and interface type (UNI/NNI). The module generates test cells,
which can be analyzed at the receiving end to check for data modifications and cell loss/insertion. Sequence error
can be inserted in the generated ATM cells using the “Insert Error” feature.
ATM Tx/Rx Test
Tx Port and Rx Port
This allows selection of Tx and Rx ports to transmit / receive the ATM traffic.
User/Network Interface
This will decide if the generated cells to be from Network side or User side. When UNI interface is selected, the
ATM cells generated (or cells being analyzed) look for GFC field and 8 bits VCI field. When NNI format is selected, the
ATM cells generated (or cells being analyzed) look for 12 bits VCI field and no GFC.
ATM Header Fields
This configures the GFC, VPI, VCI, PT, and CLP with the appropriate values for transmission of ATM cells.
Tx Config
This option allows users to configure the bandwidth in Packets per second, displays the configured rate in
bits/second and the percent of the bandwidth utilized on the selected interface.
Statistics
The module displays the statistics of the transmitted and received packets. In addition, it displays the Rx
Sequence Resync count, Error count, Tx Overrun count, & Rx Underrun count.
PoS Tx/Rx Test
This application provides users the option to send the test packets with fixed, random, or variable lengths,
and insert user-defined frame header in the packets transmitted. The statistics displays the transmitted and
received packets, lost packets and receive sequence erred packets. The Rx sequence errors can be categorized
based on Rx error stat length bucket value set.
PoS Tx/Rx Test
Tx Port and Rx Port
The interface allows users to select the Tx and Rx ports to transmit / receive the PoS traffic.
Fix/Var Packet Length
This option allows users to select the fixed, variable increment, and random type of packet for transmission/reception.
Tx Config
This option allows users to configure the bandwidth in Packets per second, displays the configured rate in
bits/second and the percent of the bandwidth utilized on the selected interface.
Statistics
The module displays the statistics of the transmitted and received packets. In addition it displays the Rx Sequence
Error count, Tx Overrun count, & Rx Underrun count.
Rx Error Statistic Length Buckets
PoS Tx/Rx Test categorizes the received sequence and data errors in different packet length groups called “Buckets”.
Each sequence error reported will be added to the corresponding bucket, there by updating the statistics. This feature is
applicable when “Var. Increment” or “Var. Random” option is selected for packet length configuration.
