LOCAL MANAGEMENT

Frames Received

Displays the total frames detected on the ring since the TRXI was last powered on or reset.

KBytes Received

Displays the kilobyte sum of all frames detected on the TRXI since it was last powered up or reset.

Errors Received

Displays the total Isolating and Non-Isolating Errors detected by the TRXI.

Beacon States

Displays the total beacon states detected by the TRXI. Stations transmit beacons when they detect bit streaming or signal loss on the ring.

Ring Purges

Displays the total ring purge frames transmitted by the active monitor.

Active Monitor Changes

Displays the number of times a different station has been active monitor.

ISOLATING ERRORS

Isolating Errors are “soft” ring errors that report the domain of a fault (that is, you can isolate the fault’s region to the transmitting adapter, the receiving adapter, and the components - cabling and wiring concentrators - between the two).

Line Errors

Displays the total line errors detected by the TRXI. Line Errors are corrupted frames that are detected by a node. This type of error normally occurs when stations enter and leave the ring.

This error can also indicate a problem with the receiver of the reporting node, or the transmitter of its Nearest Active Upstream Neighbor (NAUN), or the cabling and hub hardware between them.
