The number of errors is not actually a problem as long as the number does not increase frequently during the operation.
If the number of errors, however, increases frequently, take the following action.
• Check the power-on/off status of the host station and other stations.
• Check the connector for disconnection and looseness; and the cable for disconnection and length.
• Perform the forward/reverse loop test from the remote master station (in the optical loop system).
