nms520DiagIntLineloop

Module: NMS520-MIB

OID (symbolic): NMS520-MIB::nms520DiagIntLineloop

OID (numeric): 1.3.6.1.4.1.498.8.2.7.1.3

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 Selftest SET this object and specifiy a blocksize. 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. The only valid responses to a READ are lineloopOn(2) or lineloopOff(1). This test will terminate after the specified number of blocks have been run. Reading test results via the nms520DiagBitErrors or nms520DiagBlockErrors objects while the test is running will cause the test to terminate prematurely and render the results invalid. Test results should be only read after the test is completed. The current Test Status can be obtained by reading this object or the nms520DiagTestStatus object on the unit under test. This test can also be terminated by seting the nms520DiagTestReset object.

What is nms520DiagIntLineloop?

Starts a line loopback (Analoop) test combined with a self-test pattern; set it to the desired block count (blocks1 through blocks50000) to begin, and the test auto-terminates once that many 1000-bit blocks have run or can be stopped via nms520DiagTestReset.

Examples
