I'm perusing eBay looking for a Digital Trunk Interface module for one of my lab BCM50's. I noticed there are two modules. One is simply a "DTM", and the other is an "EE-DTM". The EE-DTM module seems to be older. Age is not an issue for me as long as their function is identical (like signaling protocol support). Other than age, I can't really find information on potential differences between the two.
Is there any significant difference to where it'd be more advantageous to buy one vs the other?
Thanks!
