3
Framing

• Investment vs. Maintenance
• Inadequate corporate solutions in the national
  market
• Geographical distribution
• Insufficient growth when compared with other
  NREN.
• Availability of a fiber provider

4
Goals A new approach!

• New infrastructure for the long run
• Gain more autonomy towards the market
• Solve the long lastingcapacity limitations
• Be side by side with the most advanced NREN
• Provide the means for high bandwidth projects and
  services

5
Goals Guidelines

• New and simpler network design
• Ethernet based
• 10GE backbone
• Nx1GE access
• Same Control panel for IPv4/IPv6
• Redundancy in the backbone through a provider
• New backbone for the whole network
• Stage I connecting Lisbon-Braga

6
Procedures

• Passive fiber network
• FO for the long distances
• Local loops using fiber
• Equipment
• Transmission (Ethernet).
• Routing (IP).

7
Procedures

• International tender for long distance cable
• Winner - Refer Telecom (Railway Operator)
• Each local loop with a different approach
• Always trying to use existing pipes

8
Procedures - Transmission

• Limited to a public announcement
• Several proposals received
• Second round with best proposals
• Best-and-Final-Offers were asked
• ADVA was chosen

9
Procedures - Routing

• Similar to the transmission, without a public
  announcement
• Several proposals received
• Second round with best proposals
• Best-and-Final-Offers were asked
• Cisco was chosen

10
Long Distance cable Features

• 48 Optical fibers from witch
• 24 x ITU-T G.652C (without water peak)
• 24 x ITU-T G.655

11
Long Distance Cable Tests made

• Tested
• Spectral attenuation
• Chromatic dispersion
• Polarization Modal Dispersion
• Reflectometry attenuation
• Insertion loss

12
Long Distance Cable Features

• Dialectical central strength member fiberglass
• 5 loose tubes 4 with 12 fibers each
• Water resistant
• Anti-rodent armouring
• Complies with crushing, tension and temperatures
  specifications

13
Cable - curiosities

• Mean attenuation of 0.21dB/Km
• Can connect 150Kms with with nothing-in-line

14
Access Local Loops

• Strategy
• use existing pipes
• establish partnerships with pipe owners
• always have a ring topology
• Developing
• Aveiro, Braga, Coimbra, Lisbon and Porto

15
Access Local Loops - Aveiro
16
Access Local Loops Lisboa
17
Access Local Loops - Difficulties

• To coordinate all involved entities to meetings
  and surveys.
• Unexpected events on-site

18
Transmission Solution

• Minimalist approach - several distinct
  point-to-point solutions
• Intelligence and services on the IP level
• The transmission is just the 10GE and 2GE access
  links
• Solution -gt ADVA Optical

19
Routing Equipment

• Cisco Equipment
• 1 router in Lisbon
• 1 router in Porto
• 1 router backup/test router
• 10G Lan-Phy XENPAK ports
• 1G SFP ports

20
Routing Topology

• Dual star topology (Lisbon and Porto)
• Network intelligence on the IP level
• No more core/edge design for the fiber
  connections (economical reasons)
• Fully redundant equipment
• Lisbon-Porto backup link from a commercial
  provider

21
Management and operation TNMS CORE

• TNMS-CORE from Siemens
• Integrated management
• Centralized monitoring and configuration
• End-to-end connection management
• Alarm and error monitoring
• Performance management

22
Management and Operation Approach

• Monitoring using another fiber pair with passive
  transceivers
• Ethernet switches directly connected to the
  transmission equipment
• Non usage of dedicated cards/equipment

23
IP Services

• Migration of current IP services to the new
  backbone
• IPv4/IPv6 Unicast and Multicast
• RD e .COM Classes of Service
• Offer new and richer classes of service
• Study the possibility of having VPNs

24
Other Connections Phase II

• Consulting market again in 2005.
• New advanced solutions of renting fiber, lambdas,
  GE and FE
• Redundancy solution for the backbone, through a
  national ring
