I didn't realise how far the Metro network went, until we discovered a box hidden under a desk when packing up for the 'move'. I agree that it was a mistake that the network was closed down considering the number of homes it passed. But wasn't the argument that it wasn't making any money?


The original CableTel architecture is basically the current RF spec with a few very minor changes.


There are new developments being made 'cable ready' (In the old 'Celtic' Region anyway can't say for the rest of the country), but ntl will never get into all sites even if they're on build.

A person (no names) in Cardiff planning team took it on himself to come up with a suitable fix for the problem, I then got involved with trialing this equipment and Cwmbran in fact started off as a few nodes that grew from that trial, there was no interactive capability, ie: no return path network because yet again the specified equipments link budget would not reach all the way to the headend, we actually trialed a forward path DFB optical transmitter to use as a return transmitter. ( approx 10.5dBm compared to return TX's approx 0dBm) This was combined at Newport and re-transmitted
back to Cardiff to enable people to purchase Front row movies and pay per view events on the analogue service.

If we had not done this development work I am sure the esteemed gentlemen at Hook would of done nothing and the area would of ended up with miles of ducts, cabinets and cabling but no TV or eventual broadband services to the area.

Did they thank us for coming up with a solution? Did they hell! the smelly stuff hit the fan as the prima donnas threw their toys out of their prams, they cancelled expenditure fro the backup feed to the area, and thats why Cwmbran has suffered outages lasting long periods on a few occassions because there was no back up facility for the area. I could go as far as to say the guy who made the tricky decision to push forward with the solution to the existing problem actually lost his job over it.

On the other subject yes, Metro were losing money but it was not a very large amount. If the Metro systems had been taken out of ntl they would of made a healthy profit, they were being dragged down by the huge expense created in large companies. They were employing full time accountants and paying extortionate sums to an external company to handle the billing. the company could of been a success with some good management and the closing of a few networks. The manager in charge of the operations was very weak and was unable to make any decisions, he wanted the whole lot to close instead of coming up with plans to turn the company into profit. He actually kept bringing the losses to ntl's attention, something he seemed to rapidly increase when he reached the age of 62 and apparently inherited a large house from an elderly relative.

The networks were closed and 37 jobs were lost because of one greedy man who wanted redundancy for himself! :rolleyes:

When Leicester Cable took over responsibility for providing the off airs to the hundreds of council flats on the Metro system we had to build new systems in them all.
Caused a few problems in parts of the city when Metro wanted to pull the plug before we had even got to them.

The underground build cost is what left the cable networks in this sorry state in the first place. The document I linked to earlier in this thread highlighted the fact that this takes 70+% of the capital investment, leaving less to be invested in the technology. Thus IMHO compared to Sky who lease a Sat, space and invest in the technology platform cable is going to struggle to keep up until the infrastructure build cost becomes a legacy issue (as it effectivly is for BT).
