Thanks for the comprehensive reply.

2. I am puzzled by this. According to Pellseinydd's table, up to 5 miles cost 4d, 5-7.5 miles 6d, 7.5-12.5 miles 9d and 12.5-15 miles 1s. I thought each pulse represented one unit with a fixed value, so how can the ratio of charges be other than 1:2:3:4?

3. I was really thinking about manual exchanges rather than the situation immediately pre-STD. How did a telephone in a kiosk work without a dial, or were all A/B boxes fitted with dials even in manual exchange areas?
