   DC is getting 771 overlaid atop 202.   
      
   This means no more 7-digit dialing. DC is the last place in the metro   
   region it still remained.   
      
   I recall all the hue and cry about how HARD it would be to remember and   
   dial all ten whole digits. I think since then cell phones have already   
   provided most of the training needed. Now I wonder who still here has   
   7D? (Besides, of course, John Levine.)   
      
   There's been little publicity over the permissive period, but while they   
   say 202 10D started 10April2021, I recall using it previously; I could   
   be wrong.   
      
   MANY years ago, it was 7D across 202-DC/301-MD/703-Northern VA; the   
   prefixes were not reused. Then we went to interstate 10D, while intra-DC   
   was still 7D. That way there could be 703-867, 202-867, and 301-867, etc.   
      
   When 301 got the 777 overlay, C&P/BA was rather clever. (BTW: 301 is due   
   a 2nd overlay, 227, at some point.) The number of intercept lines on a   
   5E/DMS is limited; overflowing those would get ugly.   
      
   So She initially allowed say 90% of the 7D calls to go through, with 10%   
   going to intercept. Over the Permissive Dialing period, while people   
   learned & the percentage of 7D calls dropped, they kept increasing the   
   intercepted percentage; finally they got to 100%.
