Note The OC3port Plus uses the VPI / VCI specified for TRANSMIT STREAM 1 to transmit IP Ping messages and to monitor responses to those messages. Therefore, for the OC3port Plus to detect a response from the device under test, that response must be sent back to the tester on the same VPI / VCI.

  • Page 222 Appendix A Applications Introduction Appendix A contains procedures that show you how to test ATM equipment policing algorithms and how to test for the effect of high traffic rates on a payload’s transmission capability. Testing ATM Equipment Policing Algorithms To provide a minimum of acceptable service, the traffic sent across most ATM connections must comply with a pre-determined traffic "contract".
  • Page 223 • Only one transmit stream’s payload can be set to BERT. The OC3port Plus does not prevent you from selecting BERT in each of the eight transmit payloads (in some cases, this is a useful way of providing random payload data in multiple streams), but you will not be able to correctly analyze this type of transmission.
  • Page 224 • • VBR / Burst The OC3port Plus can be configured to provide up to eight individual ATM transmission streams, and, for each stream, one of these four transmission sources must be selected. Appendix B describes these transmission sources and provides examples of their use.
  • Page 225 (Peak Cell Rate) Determines the amount of bandwidth consumed by the CBR source and the inter-cell arrival times for the periodic transmission. The OC3port Plus places cells in transmission queue that are separated by a minimum interval equal to the inverse of the PCR. If a cell slot is not available at that interval, the next open slot is used.
  • Page 226 Examples The examples that follow are accompanied by graphs that depict the actual transmission queue output of the OC3port Plus. These graphs show instantaneous bandwidth plotted against time. In addition, each graph presents the average bandwidth used by each individual transmission stream.

  • Page 228 OC3port Plus ATM Transmission • Idle segment The OC3port Plus transmits cells at the SCR rate until it reaches the end of its transmit queue. Then, the OC3port Plus starts again with the stress segment and the cycle continues. VBR / BURST Parameter Setup Many parameters affect the way VBR / BURST works: •...
  • Page 229 OC3port Plus Users Manual Example 3: Stream 1 configured for VBR / BURST as follows: • : 50.00 Mbps • :10.00 Mbps • : 10.00 Cls, • : 2.00 CDV LIM A fast, high-speed burst followed by a slow sustained rate and a tight CDV.
  • Page 230 The "x’s" indicate actual cell transmissions. Notice how the OC3port Plus transmits a 10-cell burst in the beginning and then quickly scales back to half the SCR rate or 5 Mbps. This shape simulates the worst-case burst allowed by the defined traffic parameters.
  • Page 231 OC3port Plus Users Manual Example 4: Dual VBR / BURST transmissions configured as follows: • Stream 1: PCR: 50 Mbps, SCR: 10 Mbps, MBS: 10 cells, CDV LIM: 2.0 • Stream 2: PCR: 25 Mbps, SCR: 5 Mbps, MBS: 20 cells, CDV LIM: 2.0 Stream 1 Average=9.66...

  • Page 234 Appendix C Glossary Acronym for Alarm Indication Signal. Not synchronized; not timed to an outside clock. asynchronous Acronym for Asynchronous Transfer Mode. A transmission protocol that relays user traffic by segmenting it into small, fixed-sized packets called cells. The ATM cells are then inserted into a framing structure and transmitted across a data link.
  • Page 235 OC3port Plus Users Manual A mode in which the OC3port Plus loops back the incoming cell loopback mode ATM cells for in-line testing. In cell loss testing, the number of displaced cells in relation to cell loss ratio the total number of cells received by the activated ATM receive filter.
  • Page 236 Appendixes Glossary Acronym for Header Error Control. That portion of an ATM cell header that performs error detection, thereby reducing the likelihood of bit errors causing information to be mis-delivered. In ATM, a type of background cell. An idle cell has its CLP bit idle cell set to 1.
  • Page 237 Acronym for Remote Defect Indication. A piece of logic that allows the OC3port Plus to discriminate receive filter among incoming data streams based on specific header information. The filter uses pattern matching to capture certain traffic record statistics based upon specific header values.
