Introduction
This chapter describes the ATM network testing functions of the OC3port Plus. It
shows you how to start cell stream transmission and how to monitor ATM cells on
an OC3 signal.
The OC3port Plus has the ability to capture cell payloads and store them in a
buffer for later viewing and analysis. This chapter also describes the cell capture
process and shows you how to set up the OC3port Plus to capture and analyze
ATM, ILMI, and OAM cell streams.
To facilitate testing and enable you to quickly assess problems with a network, the
OC3port Plus has an automatic testing function. These tests can automatically scan
virtual circuits for ATM activity and identify for you which circuits are in use.
This chapter shows you how to set up and run these tests and how to interpret the
results provided about the detected circuits.
To simplify the process of configuring the OC3port Plus to perform ATM network
testing, the OC3port Plus provides four pre-configured traffic templates. These
templates, which are described in this chapter, provide complete transmission
stream parameters for up to four transmit streams. Using these templates, you can
easily set up and modify more complicated cell streams.
The OC3port Plus has three Quality of Service (QoS) tests: Cell Loss, Cell Delay
Variation, and Cell Transfer Delay. This chapter provides details about the
operation of these tests and shows you how to set up, run them, and interpret their
results.
The OC3port Plus can transmit ATM BERT test patterns. This chapter describes
the operation of the BERT test and shows you how to configure the tester's BERT
function and run a BERT test.
The OC3port Plus provides IP Ping capability, which enables you to test
connectivity to devices on the IP layer. This chapter shows you how to set up the
tester so that you can send and receive IP messages.
