If that's your cab, don't tell 'em when they ring, if they are that pants, you don't want them near it.

Mine is 53 or would be if my phone line was active.

There are three quite tall cabinets on the opposite side of the road near our flats. I note that one of the cabinets has the door open or ajar always. I'm not sure there's in use equipment in there as there's a mess of wires and crisp packets in there!. On the corner of the road a bit further up, there's a single smaller one. Must take a pic of them. Using https://www.btwholesale.com/includes/adsl/main.html mine says cabinet 29 for the exchange name, listing FTTC and below.
