Extreme weather, the
consequences for
telecommunications
Senioradvicer Terje Olav Øen,
Emergency Medical Service Department
Weather conditions
•
The society has to be prepared to take care of
situations where we have got a lack of
electrical energy and power supply.
•
This section will primarily discuss problem
related to:
Disconnection from network
Lack of power supply
Svalbardgruppen 31.aug. 2012 Ålesund

Different causes
•
Lightning
• Avalanche – snow and rocks
• Stormy weather
falling trees
sea flooding
damaged roads and
broken cable performance
|3
Subjects
Cable performance – information transfer
Telephony
Data
Radio communication
Mobile cellular network
Tetra-network: Virvle, Rakel, Sine og Nødnett
Power supply
Demand of redundancy
Measures

Extreme weather
Definition of "Extreme weather”
The wind or the falls are so
strong, the expected water
levels or the risk of
avalanches that high,
that lives and values can be
lost if the society is not
specifically prepared for the
situation.
It concerns a surface of
important size, for instance
a county.

A structure of telenet.
FS I has contact with
all FS II centrals –
that have contact
with each other.
Interconnection –
centrals that have
high traffic levels

PSTN - Public Switched Telephone Network
•
Analogue telephony
•
Analogue telephony did function without extern
power supply (until 15th of Dec 1998)
• Demand for emergency service / lifeline service
• Today: no regulations or public demands
•
1997: Network digitalised: voice and data
signal
•
fiberoptical cables, radio line, satellite communication
•
ADSL ( Asymmetric Digital Subscriber Line)

Public telephony network
PSTN subscription don’t give guarantee for
power supply for end users communication
units

GPoC – public health
communication centrals
Probably a lot of small call centres
without risk analysis in the municipality
Vulnaribility: traffic overflow

End user: The public

Redundance
What we have to do:
•
Government and authorities
• Services and organizations
• End users - the public – our patients
Systems required operational 24/7
High risk and consequences of failure
• Telecommunication
• Power supply - electricity
Redundancy for telephony networktransmission

Need for redundant solutions
Power supply
Loss of power supply caused by Dagmar

| 35
Redundant cellular network
PT suggests:
• Program for strengthening capacity and
coverage of mobile signal in priority area
• Increase with 1 000 mobile sites
Back up for power supply
• All mobile sites: 6 hours (battery or power
engine)
• Primary: all area covered by mobile signal
| 36
Back up for power supply
Ekom network:
all parts need a back up
Provider is responsible for network supply
and transmission
End user:
responsible for a back up solution on
their own
