- Caller ID (and most other CLASS features) were invented for and
- first implemented on the 1A ESS(tm) switch in the early 1980's, using
- CCIS 6 (pre-SS7) signaling. Most trial areas did not allow Caller ID
- into customer hands because of all the un-resolved 'privacy' issues.
- (Harrisburg, PA was one of those areas.)
