nms520DiagExtLineloop

Module: NMS520-MIB

OID (symbolic): NMS520-MIB::nms520DiagExtLineloop

OID (numeric): 1.3.6.1.4.1.498.8.2.7.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Lineloop (or Analoop) can be either a Bilaterial or Unilaterial loopback depending on option ddsDteTermaloop. To initiate a Lineloop with no Selftest SET this object and specifiy external, this will allow the data from the DTE to looped back to itself. Emun external(3) is write only. The only valid response to a READ is lineloopOn(2) or lineloopOff(1). To halt this test you must SET the nms520DiagTestReset object. Reading test results via the sc5520DiagBitErrors or nms520DiagBlockErrors objects while the test is running will also cause the test to terminate. There are no test results associated with this test.

What is nms520DiagExtLineloop?

Obsolete control for an external (Analoop/Lineloop) loopback test without self-test; set to external(3) to start it, and it must be stopped via nms520DiagTestReset since reading the bit/block error objects mid-test also terminates it.
