Question... the card NM-1T3/E3 supports all the same features that a NM-1A-E3 card does?!


I ask this because a customer has ordered the wrong one, and now we're kind of having problems to get a new one (the correct). Is there any document that I can look to find a way to translate the config to meet the NM-1T3/E3 card needs?!


Thanks!

Actually these are very different cards so that many commands are different. However if the circuit is working, most of the time the defaults will work ok and you just need to configure the IP address.
