Input Module Ports Status


The Input Module Port Status screen provides information on input port status, phase data, frequency data, MTIE data, and error counts. The screen's fields are described in the table below.

Error Counts

 

Error Count

Number of errors detected

Clear Count

Number of times error cleared alarm threshold

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.
