I've been reading about the differences between WE and Nortel
switching platforms, particularly in the digital age. WE went with
centralized codecs, while Nortel used a codec per line.
I too find the DMS to be an inferior switch.

That's the thing, NYNEX wasn't THAT dedicated to toll collection,
particularly since this was post divestiture and Long Lines still
provided the instate toll service.

Charging units seem strange to me too. Rhode Island has always had
bizarre toll boundaries.
For example, if you have a Providence rate center number you can call
85% of the available exchanges in the state. If you have a Pawtucket
rate center number, it drops down to 65%. And heaven forbid you live
in south county and end up with a North Kingstown number because
Providence is toll from there.
VoIP gives lie to those artificial toll rates. I can dial anywhere and
not incur any additional charges. Kind of nice when your local calling
area spans continents.
