nms520DiagExtDataloop

Module: NMS520-MIB

OID (symbolic): NMS520-MIB::nms520DiagExtDataloop

OID (numeric): 1.3.6.1.4.1.498.8.2.7.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: To initiate a Dataloop test with no Selftest SET this object and specifiy external, this will allow the data from the DTE attached to the far end unit (sc5520) to looped back to itself. Emun external(3) is write only. The only valid response to a READ is dataloopOn(2) or dataloopOff(1). To halt this test you must SET the nms520DiagTestReset object. Reading test results via the nms520DiagBitErrors or nms520DiagBlockErrors 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 equiptment.

What is nms520DiagExtDataloop?

Starts an external Dataloop test without self-test, looping data from the DTE attached to the far-end unit back to itself; set to external(3) to start, and stop it via nms520DiagTestReset since reading bit/block error objects mid-test also terminates it.
