What is bdlocIfCarTrans?

This counter tracks the number of times the carrier signal (used on serial lines to indicate the remote device is connected) transitioned between up and down. Network engineers use it to diagnose intermittent link issues. Example: bdlocIfCarTrans = 47 indicates the carrier has gone up/down 47 times; a high number suggests an unstable connection or a flaky modem.
