   We did not provide staff members' voice service, only the data   
   connection to our lab.   
      
   When the ISDN service ended, it was convenient for those of us who   
   switched to CLEC ADSL to have that extra known-clean pair to our   
   homes; folks who were trying to run ADSL on top of an existing   
   unbundled ILEC voice circuit had a much harder time with installation   
   and a great deal of finger-pointing between the two carriers.   
      
   (Of course now we all have our Internet connectivity via DOCSIS, and   
   much of this region -- although not Cambridge -- has three competing   
   facilities-based carriers, Comcast, RCN, and Verizon FiOS.)
