Other Applications of OC3-T3 Analyzer
Record, Playback Packets and Cells
These modules allow users to transmit and capture packets from
file or to a file over OC-3/STM-1 and OC-12/STM-4 interfaces.
Offlinutility can convert it into GL’s HDL file format or PCAP
Transmit Packets from File
Transmits packets / cells from the file.
Packets can be transmitted either continuously, limited by
number of packets/cells, or till the end of file (EOF).
Transmit packets/cells at a user configurable rate.
Transmits on the same port as captured, swaps ports or uses
a specified port.
Provides the statistics of the transmitted cells at both line
level and payload level.
Transmit packets synchronously on multiple boards
Receive Packets to File
Hardware provided versatile multiple filters can be applied to
incoming data on each individual port to allow traffic of
interest only. ATM and PoS traffic can be filtered at hardware
level to target traffic of interest only.
Allows Wirespeed capture of all payload from SONET/SDH
envelop transparent of transport level.
Captures the received packets synchronously on multiple
boards into a file up to hard drive capacity.
Packets can be captured continuously (till user manually stops
the capture or up to hard drive capacity) or limited by a
specified size in MB, a packet count, or a specified time limit.

Software Loopback (Rx-To-Tx Memory Loopback)
This application is used for diagnostic purposes. It loops all the
received packets / cells from the SONET to the transmitting ports
and displays the Tx and Rx information. Memory Loopback
application uses both ports on the selected board.

Alarms and Errors Counters Monitoring
The alarms and error monitoring window provided for each of
the OC-3/OC-12 port displays detailed status of the
communication with the other end.
Hardware LEDs are provided
on the card to read line
Monitored Alarms and error
counts include –
Line errors such as OOF,
FCS, Rx / Tx Abort, and
MIN / MAX Length
Line, Path, and Section
error counts
