4. © 2005 E.ON31 October 2015, Central Networks, Page 4 Future Situation 1.21CN Problems – IP based solution ?? 2.Comms WILL be different in X years time 3.Legacy systems WILL require replacing (Microwave, UHF, Pilots) 4.Existing PW’s will suffer higher failure rates

5. © 2005 E.ON31 October 2015, Central Networks, Page 5 Future Transport 1.Needs to be easier to manage. 2.Faster to deploy. 3.Lower cost to install. 4.More resilient – Self Healing, Failover etc. 5.Support Hot sites. 6.Backward Compatibility. 7.Wired and wireless.

6. © 2005 E.ON31 October 2015, Central Networks, Page 6 The Solution IP – Internet Protocol. 1.Why ? – It’s a world wide solution. 2.Future proof. 3.Low cost. 4.Securable. 5.Manageable. 6.Supports, Mobile, Wireless, Fibre, Cable, Microwave and POTS! etc.
