I wonder if you understand the term switch ? It's basically the whole telephone exchange.
No exchange is totally redundant - they are like big computers - bits are redundant but there are many ways they can just fall over (just like any computer system) - be they BT or NTL exchanges.
BT exchanges fail as well (we used to call them exchange isolations). I was involved a few such failures while I worked at BT (not the cause I might add
).
The system often consists of a major exchange with satellite exchanges hanging off it - and if the main exchange (switch) falls over then all the satellites are taken out as well.
