Description: To initiate a Remoteloop with Selftest SET this object and specifiy a blocksize. The remote unit will go into remoteloop and the master (the sc5520) unit will go into Selftest. The sc5520 transmits an in-band command to its remote DSU, directing the remote to loop received signals back onto the network. The DSE is configurable to send (and accept) either a V.54 or a PN 127 remote loop command. The remote DSU must be configured to accept the same command the DSE transmits. The sc5520 enables its internal Test Pattern Generator to provide the signal for the Remote Loop and enables its Test Pattern Checker to verify the signal. The DSE is isolated from its DTE while the Test Pattern Generator and Checker are enabled. The blocksize indicates the number of blocks the Selftest pattern generator will run. There are 1000 bits/block. Emuns 3 through 10 are write only. If option Remlooptimeout is enabled then the maximum test time is 10 minutes otherwise block size time is used. The only valid responses to a READ are remoteloopOn(2) or remoteloopOff(1). This test will terminate after the specified number of blocks have been run. Reading test results via the sc5520DiagBitErrors or sc5520DiagBlockErrors objects while the test is running will cause the test to terminate prematurely and render the results invalid. Test results should be read only after the test is completed and are available from the master (sc5520) unit. The current Test Status can be obtained by reading the sc5520DiagTestStatus object on the master unit, reading test status on the remote unit may interfere with the diagonostic test pattern and cause errors. This test can also be terminated by seting the nms520DiagTestReset object.
