Description: Point to Point Application only. To initiate a Remoteloop test with no Selftest SET this object and specifiy external. The sc5520 DSE transmitt 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 PN127 remote loop command. The remote DSU must be configured to accept the same command the DSE transmits. Emun external(3) is write only. The only valid response to a READ is remoteloopOn(2) or remoteloopOff(1). To halt this test you must SET the sc5520DiagTestReset object unless option RemLoopTimeOut is enabled. If enable maximum test time is 10 minutes. Reading test results via the sc5520DiagBitErrors or sc5520DiagBlockErrors objects while the test is running will also cause the test to terminate. There are no test results associated with this test. Reading test status on the remote unit via nms520DiagTestStatus may interfere with the diagonostic test pattern generated from the terminal equipment. The Remote Loop Function is for use ONLY on point to point links.
