Utter tosh.

Indeed.

I'm an OAP and can be extreeemely critical!

Or does he mean it's OK if I die because I can't phone an ambulance, or a centre with fifteen like me catches fire, in which case I wonder what his priority list for survival rights looks like and where he would be on it?

You have to admit, Zarjaz & MadMan, he is quite hilarious at times.

I would imagine that a system x had it's own yellow battery packs behind the mysterious grey panels plus a generator. The 999 service responsibility was taken very seriously back in the days of system x install.

Yep, they have battery packs which are only designed to run for an hour or so, as the standby generator should be up to speed within a minuite.

In the good old days of clockwork, the batteries had to last a day or so as often there was no standby generator.

LOL. as you say, utter tosh.

It went out when clockwork was replaced with system x/axe10.

It may be something to do with the name Bob. I seem to remember another Bob a few years ago, who also talked a load of tosh (as Zarjaz says)

And - this laptop, being my second Toshiba, has the network name Tosh2 in Windows, and because of the way our cat walks his nickname is Tosh.

What else do you know about me MadMan?

Ah - perhaps there has been a leak . My brother was at one time in his life a GPO telecoms engineer. Took me ito an exchange once to show me the Strowger serried ranks clattering away to each other. Triffids have nothing on them.

The first bit is wrong, but you take the biscuit with .....

"Another last ressort is each subscriber wil have a class of service so they can use that to conserve the batteries. Ordinary subscribers would get cut of first then businesses and less critical users such as OAP homes etc"

Utter tosh.

Now, I may only be a software engineer, and worked on AXE-10 systems for mobile rather than fixed-line installations, but I did get a good grounding in the overall system design in my years at Ericsson.

In all that time, I never came across any way that the system could shed power load gradually. Yes there were ways to reduce traffic load, but not power.

Knowing the way that the system is designed, there isn't a way to reduce power to the group switch, or to any of the central or regional processors, or to any of the trunk hardware. The only way to reduce power to certain subscribers would be to concentrate critical subscribers onto certain hardware, and cut power to the remainder; but (a) I haven't seen that capability, and (b) that goes against the principle of spreading your critical subscribers over different hardware in case of other failures.

At the software level, on the mobile side, there was a lot of effort put into certain robustness & recovery features, to cope with failures etc. But I can say for a fact that extending operation time when on battery was not one of them.

I remember many an day spent bank cleaning & oil dagging Strowger selectors when I was a lad

The worst noise was in the STD routing unit. The normal selector units weren't too bad.

Much better than modern exchanges. In those days you were an engineer, but nowadays they need trained monkeys (bit unkind ain't I)

i bet it was ! LOL
