Sometime in the past month, the sound quality of my AT&T ld calls improved tremendously - you can practically hear Sprint's pin drop. Does anyone know if they've recently upgraded their lines? My calls (Phila to CA, CT, NY, GA) are (to my ear) totally without background hiss, so much so that the first few times I thought the calls were on the way to an interception recording.

A very good signal-to-noise ratio is characteristic of digital transmission. This is a long-term strategy, and is still in progress. If you suddenly noticed an improvement on all of your calls, it is more likely that a new higher-quality facillity has just been installed between your local central office and the AT&T switch (point of presence) serving your area. -- Dave Levenson Westmark, Inc.
