Description: Determines the current line condition status of the link. In order to turn on a loop, the link must be configured In Service. ok (0) - In Sync yel (2) - Yellow Alarm ais (8) - Sending All Ones lof (32) - Loss of Frame los (64) - Loss of Signal red (2048) - Red Alarm cfa (4096) - Carrier Frame Alignment oos (65535) - Out of Service txSlip (2097152) - Transmit Slip rxSlip (4194304) - Receive Slip slip (6291456) - Transmit/Receive Slip sef (8388608) - Severely Errored Frames underTest(1073741824) - Running Bit Error Test (BERT) errors (2147483647) - Multiple Errors displays raw bit field value

What is dsx1TestLinkState?

Reports the current line condition of a DS1/E1 link as a bitmask value such as ok(0), los(64) for Loss of Signal, ais(8) for all-ones alarm, or underTest(1073741824) while a BERT is running. An admin polls this to see whether a link is clean or alarmed before attempting to enable a loopback, since loops require the link to be in-service.
