Page 64 condition (Gate Time) is met. If SDT is enabled and alarm/error triggers are selected, the results will appear in the Results section under the SDT tab. Testing Process The test set measures how long the event remains present after it is first recognized and will continue to measure the total service disruption time in the event of multiple disruptions.
Page 65 In the simplified example above, two events occur with 150ms of error free time in between. A gate time of 300ms counts them as one service disruption because the error-free section is less that the gate time. Using a gate time of 100ms to evaluate the same situation would coun two service disruptions, because the Gate Time condition is met within the error-free section.

Page 391 Program Clock Reference (PCR) MPEG TS normally contain a built-in timing packet known as the Program Clock Reference (PCR). Recovering the 27MHz clock at the decoder end of the transmission system is necessary to re-create the video signal. The PCR values need to be correct at the signal origin and should not be distorted along the transmission path to a point where decoding the compressed signal becomes problematic.

Page 393 15.17 Layer 4+ Applications Stateful TCP testing refers to the validation of TCP connections used for the TCP/IP Protocol Stack. A V-Perf test will validate that the TCP parameters in the network were set up correctly. The optional V-PROBE is used as remote server to establish TCP connections and validate that the network is configured correctly for seamless passing of TCP traffic.
Page 394 TCP is a connection oriented protocol. A Connection is established prior to data transmission between the two end devices (client and server). A 3-way handshake procedure is used to establish connection. When a connection is established, the data transfer can start. TCP uses sequence numbers to reassemble data and verify that no data has been lost.
Page 395 TCP Bandwidth Delay Product is the theoretical maximum of data that can be transmitted based on network delay and throughput rate. Link Bandwidth (bps) x RTT (s) BDP (Bytes) = To completely occupy the available bandwidth the Window size must be set to the BDP value. The ideal TCP transfer time is based on the Maximum achievable TCP transfer rate, calculated based on the Bottleneck Bandwidth (BB) and the layer 1-2-3-4 overheads associated with the network path.

16.0 Fiber Channel Fiber Channel Applications Introduction Enterprises worldwide rely on complex IT infrastructures to store and maintain critical data and applications. Storage Area Networks (SANs) have evolved to improve availability, resiliency, performance, modularity and geographical distribution of data storage systems and Fiber Channel is an important technology for linking SANs together.
Page 424 Buffer-to-Buffer Credit Estimation - To avoid loss of frames during transmission, the Fibre Channel protocol uses a buffer-to-buffer flow control mechanism between link partners. During the login process, the remote node informs the local nodes as to the number of receive buffers it has available.
Page 425 The Fiber Channel Main Menu provides shortcut application buttons for FC BERT, FC RFC 2544, FC Throughput, FC Loopback, and IP testing. Some test capabilities or test rates may be specific to the product configuration or may require the purchase of a software option in order to be displayed or be enabled.

improve the relationship between measurements on signals and receiver performance in terms of bit errors. The unit transmits a "compliant pattern" which consists of a valid Fiber Channel protocol frame (SOF, payload, CRC, EOF) containing a test pattern as the payload.
Page 433 FC-2 BERT - Payload Setup BERT Testing Tips A BERT samples every incoming bit and looks for something that doesn't occur often. This traditional method typically used in SONET/SDH measurements, can however take a very long time. For example, in a 1Gbps Fiber Channel system, errors occur on average once every 1000 s (about 17 –12 Min) for 1x10 BER, so you would need to detect at least 10 to 100 errors before you can have...
Page 434 FC-2 Header Format The Frame Header is the first field of the frame content and immediately follows the SOF delimiter. The Frame Header is used to control link operations and device protocol transfers as well as detect missing or out of order frames. The values of each field can be edited depending on network setup and test scenario.
Page 435 The S_ID is a three-byte field (Word 1, Bits 23-0) that contains the address identifier of the source Nx_Port. Type (Data Structure Type): The data structure type (TYPE) is a one-byte field (Word 2, Bits 31-24) that identifies the protocol of the frame content for Data frames.

Page 524 21.0 1588v2/PTP Through Mode & PDV Analysis 1588v2/PTP Home Menu When placed in 1588v2/PTP Through Mode, the TX320S makes use of both ports to analyze network 1588v2/PTP traffic exchanged between Master and Slave. The unit can be inserted on the network path in passthrough mode between P1 and P2 or non- intrusively via a network tap.
Page 525 In 1588v2/PTP Through mode, traffic forwarding between P1 and P2 becomes active as soon as it is connected on the network, however measurements and statistics are only active after pressing Start. Go back to top Go back to TOC 21.1 Port Setup Port setup is accessed via the Setup menu located on the Home page.
Page 526 1 GE Copper Port Setup 1 GE Copper Port Auto Negotiation: On or Off. Matches the test set's negotiation settings to those of the link partner. Speed (only when Auto Negotiation is Off): 10 Mbps or 100 Mbps. Duplex (only when Auto Negotiation is Off): Half or Full. Advertisement (only when Auto Negotiation is On): Default-All or Custom.
Page 527 The Status tab lists current port settings. Please note that the Status tab is only available if a fiber port option is selected from the Test Port Selection menu. Test units shipped before January 2012 support up to +/- 50 ppm offset only. Units shipped from 2012 onwards, support up to +/- 150 ppm offset.
Page 528 Delay Measurement: End to End (M>S, S>M) and BC-TE measurements are the same value, except that BC-TE measurements have additional parameters. Both modes require a 1 PPS clock source (Ext. 1PPS, Atomic 1PPS, or GPS 1PPS). End to End (M>S, S>M): Measures the M>S Master to Slave (T1, T2) and S > M Slave to Master (T3, T4) delay based on the monitored messages Sync and Delay_req/Delay_response timestamps.
Page 529 Forward TE Threshold: When enabled, triggers an event when the measured Forward TE (T1) exceeds the configured threshold. Threshold values are from 100ns to 1000 us. Reverse TE Threshold: When enabled, triggers an event when the measured Reverse TE (T4) exceeds the configured threshold.
Page 530 Indicator Symbols A T indicates that the test set is in Through mode. A green light indicates a successful connection. If the Light is gray, it indicates that there is no valid 1588v2/PTP traffic detected.

Page 531 Additional message information is displayed on the Messages screen. Messages The Messages screen gives a further breakdown by message type. The total and per second average message rates are displayed. Messages Decoder The Tracer shows the 1588v2 messages from both Master and Slave clock devices. There are four function keys: Pause/Continue - to pause or continue the tracer.

Page 533 Ethernet Stats include 1588v2/PTP traffic and non 1588 traffic. It displays Port 1 and Port 2 Ethernet traffic measurements. Tap on P1 and P2 to switch between port 1 and port 2 measurements. For more information on Ethernet traffic tabs and measurements, please refer to the BERT Results section.
Page 534 Reverse TE: Measures Reverse Path (Slave to Master) Time Error, based on Delay_response (t4) message and t’3 measured by test set in Through Mode and configured cable delay. 2Way TE: Uses Forward TE and Reverse TE measurements to computed 2Way TE. Refer to Time Error Test for Boundary Clock for a graphical representation of Forward, Reverse, and 2Way TE.
Page 535 Sync PDV: Monitors TIE of Sync Messages Follow Up PDV: Monitors TIE of Follow_Up Messages Slave Wander: Monitors Slave TIE based on Delay_Request Messages (Note that t3 delay_request timestamp is not always present in the messages originating from the slave). Delay Req PDV: Monitors TIE of Delay_Request messages based on Delay_Response (t4) timestamps.
Page 536 Tap on PDV Analysis to view the PDV graph and perform Delay/PDV Analysis per ITU-T G.8261.1 standard. The objective of this category of PDV metrics is to study the population of timing packets within a certain fixed cluster range starting at the observed floor delay.
