and the fifth (or least) and final cause of interruptions was “Transmission” – failure or
malfunction of transmission equipment including insulators, large transformers, lightning
arrestors, and switches.

Telecommunications Service Quality Measurements
This section has historically contained charts showing Hawaiian Telcom’s
Average Service Compliance Levels for the Fiscal Year. Beginning with Hawaiian
Telcom’s June 2011 filing, these quality measurements are being filed as confidential
and can’t be revealed publicly. Therefore, the Commission can no longer publish this
data. The Commission continues to monitor Hawaiian Telcom’s systems and activities
to resolve issues and address customer concerns and complaints.
