3. When finished, press ESC.

HI-FREQ: This pattern has a high transition of ones and zeros.It is generated by repeating the D21.5 sequence (composed ofalternating D21.5+ and D21.5-); it contains the 1010101010-bitsequence. A repeating D21.5 pattern has the highest transitiondensity; these characteristics make this pattern useful for testingrandom jitter and asymmetry of transition times.

LO-FREQ: This pattern has a low transition of ones and zeros. It isgenerated by repeating the K28.7 sequence (composed of alternat-ing K28.7+ and K28.7-); it contains the 0011111000 1100000111-

bit sequence. A repeating K28.7 pattern has the lowest transitiondensity; these characteristics make this pattern useful for testing

low frequency random jitter and PLL tracking error.

MIX-FREQ: This pattern has a low transition of ones and zerosmixed with a high transition of ones and zeros. It is generated byrepeating the K28.5 sequence (composed of alternating K28.5+and K28.5-); it contains the 00111110101100000101-bit se-quence. A repeating K28.5 pattern has a 50% transition densityand a 50% mark density; these characteristics make this patternuseful for testing deterministic jitter.

1111: Industry-standard all ones pattern.

1010: Industry-standard alternating ones and zeros pattern.

0000: Industry-standard all zeros pattern.

CJTPAT: Compliant Jitter Tolerance Pattern is for jitter measure-ments. It is intended to expose a receivers CDR (Clock and Data

Recovery circuit) to large instantaneous phase jumps. The patternalternates repeating low transition density patterns with repeatinghigh transition density patterns.

CRPAT: Compliant Random Test Pattern is intended to provide

broad spectral content and minimal peaking that can be used forthe measurement of jitter at either a component or system level.

CSPAT: Compliant Supply Noise Pattern creates the worst casepower supply noise introduced by the transceiver. This noise iscaused by the switching output of the power supply.


FRAME LENGTH (only in FC-1/FC-2 Testing)Choose a value by pressing SHIFT and using the numeric keypad.

The range of frame length is from 24 to 2140 bytes with steps of4 bytes. The default value is 28.

TRAFFIC SHAPINGOptions: CONST (F1), RAMP (F2), BURST (F3), EDIT (F4)

Traffic Shaping is available in FC-1/FC-2 and ESCON Testing.

CONST: Constant trafc means that the trafc is transmitted

at a constant rate (from 0100% Bandwidth) for the entireduration of the test. A bandwidth of 100% corresponds to an

interframe gap of 6 idle sequences.

RAMP: The trafc is transmitted at a variable rate from a START

BANDWIDTH (between 0100%) to a STOP BANDWIDTH(between 0100%), with increments of STEP (between1100%). The ramp is repeated for the duration of the test.

BURST: The trafc is transmitted at a variable rate. The trafc

will be transmitted at BANDWIDTH #1 rate (from 0100%)for DURATION #1 seconds, then at BANDWIDTH #2 rate(from 0100%) for DURATION #2 seconds. This sequenceis repeated for the duration of the test.

D_WWN: This is the same as S-WWN, but for the far end devicethat will be connected.

Each device in the SAN (Storage Area Network) is identied by aunique hex 64 bit WWN (World Wide Name). The WWN containsa Company ID field, which is defined and maintained by the IEEE,and a vendor info field.

Currently, there are two formats of the WWN as defined by the

IEEE. The original format contains either a hex 10 or hex 20 inthe first two bytes of the address. This is then followed by theCompany ID information.

The new addressing scheme starts with a hex 5 or 6 in the firsthalf-byte, followed by the company ID in the next 3 bytes. Thevendor info is then contained in the remaining bytes.

2.3.1.

BERT in Section 2.2.

Bandwidth Sweep test in

Section 2.3.2.

RFC2544 in Section 2.3.3.

Figure 61 Loopback Configuration Screens

Loopback is only available for PORT 1. The trafc loopback featureprovides a manual mode or a controller/responder mode.

In MANUAL mode, press START (F4) to load the loopback soft-ware to begin looping incoming trafc. During this process the link

will be closed. It will reopen at the end of the download.In CONTROL mode, the test set will be responsible for sendingloop up and loop down commands to a remote test set configuredas a responder.

In RESPOND mode, press START (F4), and the test set will scanincoming traffic for a loop up command. As soon as loop up com-mand is received, the test set will switch to loopback mode and itwill loop back all incoming trafc on PORT 1. The incoming trafcwill be looped as follows:

If FC-1 loop up code is received, the test set will retransmitthe incoming frames without modifying them.

If FC-2 loop up code is received, the test set will retransmitthe incoming frames and swap the source and destination

identifiers.The responder will remain in loopback mode until it receives aloop down frame.Note: Use caution when using loopback mode because networkequipment may not allow the loopback of unicast frames.

The configuration screens, shown in Figure 61, contain:


61/86

61SSMTT-30Z

MODEOptions: MANUAL (F1), RESPOND (F2), CONTROL (F3)Select the loopback operating mode.

Note: When MODE is being configured, the test set will momen-tarily loose the connection between itself and the connected node.Once the connection is reestablished, the SIGNAL and FRAMELEDs are green.

MANUAL: Press START (F4), and the test set will immediately

start looping the incoming traffic on PORT 1.

RESPOND: Press START (F4), and the test set will act as

a responder. At this point, WAITING is displayed, and the

test set waits for a loop up command frame. Once a loop upframe is received, LOOPBACK TEST IN PROGRESS DO

NOT DISTURB is displayed. The test set will then loopback

traffic as was previously described in the paragraph starting

with Congured as a responder.

The test set will continue to loopback trafc until a loop down

frame is received, or ESC is pressed on the test set.

CONTROL: Press START (F4), and the test set acts as a

controller.

Once the MODE is set, the following items may be configured:

COMMAND (CONTROL MODE only)Options: LOOP-UP (F1), LOOP-DN (F2)

Select the type of frame to send after pressing START (F4).

LOOP-UP: Send a loop up command to a remote responder(test set).

LOOP-DN: Send a loop down command to a remote responder

(test set).

FORMAT (MANUAL and CONTROL MODES only)Options: FC-1 (F1), FC-2 (F2)

If MODE is set to MANUAL, the FORMAT setting determines howthe test set will loop back the incoming trafc.

FC-1: The test set will retransmit the incoming frames withoutmodifying them.

FC-2: The test set will retransmit incoming frames and swapthe source and destination identifiers.

If MODE is set to CONTROL, the FORMAT setting determinesthe format of the loop up and loop down commands.

FC-1: The test set can transmit an FC-1 loop up or loop downcommand to a remote test set configured as a responder. Uponreceiving the FC-1 loop up command, the remote test set willretransmit unmodified incoming frames.

FC-2: The test set can transmit a FC-2 loop up or loop downcommand to a remote test set configured as a responder.

Upon receiving the FC-2 loop up command, the remote testset will retransmit the incoming frames and swap the sourceand destination identifiers.

Controller ModeWhen ready, press START (F4), and the test set will be placed incontroller mode and it will send a loop up or loop down frame.

When the loop up command is transmitted, the test set will verifythat the remote test set (responder) is properly looped up. Duringthis time, the test set screen displays:

LOOP-UP VERIFICATION PLEASE WAIT...

If the loop up is successful, the test set screen displays:

LOOP-UP SUCCESSFUL

If loop up is not achieved, the test set screen displays:
