Actually a lot of NYC exchanges in the 1960's still used panel switching which was a bit newer than the original Strowger SXS offices. However a lot of rural areas used Strowger type switches made by several manufacturers into the 1980s. Eventually they had to be replaced because they couldn't provide equal access and other modern features and also required too much maintenance. Modern switches are much more reliable and energy efficient. |
