From what I remember they weren't really used even then.
Apart from 'uncompressed 64k telephony audio' pretty much everything actually
used AAL5 so that data could be compressed.
I do remember PCI ATM cards that could be used for TCP/ATM to the desktop.
The equipment you needed in the network rack to make it work was stunning.
Completely killed by 100M ethernet over twisted pair.
