In article <3853@galena2.UUCP>, Justin A. Smith asks:

- does V.42 use the zipp-lemfel (sorry about spelling :-) )
- compression. When i was working at BT they were doing somthing like
- this. Is this the resulting standard???? 

CCITT V.42bis is based on Lempel-Ziv-Welch compression, with 
extensions created at British Telecom and Hayes Microcomputer 
Products.

Did you work with Alan Clark at BT?  Did you know that he is no 
longer with them, but is now technical director at Dowty?
