Module: SC5520-MIB

OID (symbolic): SC5520-MIB::sc5520DiagExtLineloop

OID (numeric): 1.3.6.1.4.1.498.8.3.7.1.2

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 sc5520DiagTestReset object. 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.

What is sc5520DiagExtLineloop?

Setting this to external(3) starts a line loopback (Analoop) with no self-test pattern, looping DTE data back to itself; the read-only lineloopOn(2)/lineloopOff(1) values report status, and the test is stopped via sc5520DiagTestReset or by reading the bit/block error counters.
