To help identify and repair the cause of random flapping on HEAnet
lines, Telecom Eireann have requested a one-hour outage on all T.E.
circuits entering Marine House. To minimise disruption, this outage is
scheduled for 10:00 on the Sunday of the coming bank holiday weekend.
Access to all HEAnet sites will be out for approx one hour during the
at-risk period (10:00 to 12:00).
T.E., working with the NOC, have isolated the problem to T.E.
equipment at or near Marine House. Their schedule is as follows:
10:00 Test the light level at the fibre entering Marine House
10:15 Change all cards in the 155 Mbit network point at MH
and if necessary change the transmit level at the exchange
10:45 15-minute test of new equipment
Time to Fix:
Scheduled at-risk for 2 hours - an outage of no more than 1 hour is
