Current Situation

1. Legacy Comms – RS232, Fibre, Microwave, PW’s, Pilots, UHF

2. Legacy Protocols – MK3, MK2a

3. Contemporary Comms – GPRS, IP, Paknet, Microwave

4. Contemporary Protocols – DNP3, WISP+

5. New NMS installed 2004

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

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.

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.

Points of interest

1. Engineering Problems !! – Earthing, Mechanics.

2. Ongoing comms costs – Tariffs, Protocols

3. IP Based, so migration path to future wireless network.

4. Remote Config, Firmware upgrades, monitoring, diagnostics etc.

5. Can Encapsulate legacy protocols

6. Security
