Ntl switch sites & hub sites have diesel engines but there have been instances where they didn't start on mains fail. (usually due to lack of regular routine maintenance, the power staff are stretched to the limit). BT have also had engines that don't start/catch fire for the same reasons I expect!
If power fails to an ntl cabinet they usually bring in a petrol genny which keeps the neighbours awake all night, until someone decides to pinch it. The batteries wouldn't last more than a couple of hours assuming they were in good nick anyway.
Maintenance & engineers are dirty words to corporate bean counters. We don't install or sell anything so are viewed as non-productive. Happens in most companies unfortunately. Nothing lasts forever but doesn't last at all without maintenance.
