SINGAPORE (Oct 24): NetLink NBN Management, the trustee-manager of NetLink NBN Trust, says it has been slapped with a fine of $10,000 by the Info-communications Media Development Authority (IMDA) for an incident that breached the service restoration timeframe stipulated in the Telecom Service Resiliency Code.

The incident which occurred Dec 13, 2016 was caused by an unintended splicing of a new secondary cable segment to the egress cable of a secondary cabinet during diversion work.

As a result, about 676 users in Tanjong Rhu were affected for a total of 14 hours and 59 minutes.

Following IMDA’s investigation, it was found that NetLink NBN Management had failed to indicate the presence of Cabinet KT-0070 in the network diagram provided to its contractor for the diversion works, and this had resulted in erroneous cable splicing by the contractor.

The incident could have been prevented if clearer instructions were given to the contractor, says IMDA.

Since the incident, NetLink NBN Management says it has taken measures to prevent such recurrence.

Shares in NetLink NBN Trust closed at 82 cents on Tuesday.
