Yes I believe it did but in my time we had 7 digit. The only phone I'd
ever seen with 2L1-4N was my grandparents 554 set. JAckson-1-4937. But
I've seen old advertising materials for the Providence area that has
2L-4N numbers on it.

Very interesting -- I knew that Panel an ESS were in existence at the
same time but wasn't aware of the #1XB.
