I suspect that there is a 256 ECI cabinet out there, look for a bigger cabinet in an ECI area. Someone should be able to get a picture for you.

I assume that each supplier has seperate geographical areas as the head ends in the handover sites are unlikely to be compatable with each others equipment.

I thought it was strange that my second line (homeworking line) when I checked for FTTC availability said 31st May 2012. Never thought about extra capacity being needed to provide it. My existing 80Mbps line has more than enough bandwidth to allow me to work from it as well as the normal domestic usage.

The original FTTC CAB was a 288 port however, about 3 weeks after it was installed, it was removed and replaced with a 128 port one!! Being a rural area, they must have thought that take up would have been very slow but with around 250-330 houses being served by the PCP, take up of fibre services must be quite high if they are going to the expense of installing another one.

All the cabs in my area, well the ones I've seen which is probably the majority are ECI 128 cabs

They have had install another cab by us, as the first 1 was full, it was only a small 1 (200 slots I was told), So it does look like BT may have got the demand wrong in some area's.

I vaguely remember there being cab shortages from the supplier a while back, if I'm not remembering wrong, they could of been installing the smaller ones where they would of otherwise put a bigger one in had they had stock.

288 is 6 cards of 48 ports each.

Cards sizes often move from 16 ports to 32 ports to 48 ports to 64 ports. Huawei seem to have 48port ones at present

With 4 Ge ports and a minimum 15Mb giving 264 ports. the dimensioning works out about right. Some ports will have products with less than 15Mb minimum on making it possible to use all 288 with a bit of luck. I wonder if the ECI 128 port cabs are 4*32port cards or 2*64 port cards ?

The result of too many years spent in computing expecting everything to be a multiple of 2 6 * 48 doesnt compute for no real world reason

You mean a power of 2?

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, etc.

These are the only numbers that exist. Anything inbetween is an illusion...

I've not yet seen any ECI 288 capacity cabinets yet! I've only seen the small 96 ones which they appear to be using in most newly commissioned areas now.

Thanks
