What is everyone using for the TA 372 ONT's?
The Adtran 454 works well. It has 4 POTS and 4 Broadband ports.
We have a few 454 ONT's. Seem to work well. If you have a need for more than 4 FXS ports, then you will have to put in a 908, 916, or 924 behind the ONT to get the number of desired FXS ports.
from what I'm getting you cant get the TA 454's now
