Error Counts |
|
Error Count |

LOS ( Secs) |
Loss of Signal - Generic term which is used specifically in different signal domains. Ranges are from 0 to 100 seconds. |
AIS ( Secs) |
Alarm Indication Signaling - A code transmitted downstream in a digital network that shows that an upstream failure has been detected and alarmed. Ranges are from 0 to 100 seconds. |
OOF (Events) |
Out Of Frame - Occurs when the framer chip cannot determine framing. Ranges are from 0 to 100,000 seconds. |
BPV (Events) |
Bipolar Violation - The presence of two consecutive "one" bits of the same polarity on the T carrier line. Ranges are from 0 to 100,000 seconds. |
CRC (Events) |
Cyclic Redundancy Checking - A process used to check the integrity of a block of data. Ranges are from 0 to 100,000 seconds. |
