The B is for Bell.
Analog phones lines increase the current to trigger the ringer. The ringer
used to be a physical bell.
Your 0.0B is most likely a cordless phone which uses house power to run, so
doesn't have a power draw when ringing.
Also, if you turn off the ringer on a phone, you can disregard the REN.
I used to use a 3Com ISDN TA for voice and it would only power 4 ringing
phones. Adding a 5th phone would cause them all to not ring. Switching off
the ringer on the 5th phone fixed the problem. It had a REN of 3, but some
of my phones had a REN of below 1.
