Interfacing with Cisco 6732, from NE providing DS3, TDM, Non-channelized. The current interface card in the 6732 is the DS3 ATM. From the data sheets there is also a DSX3/CHNL card available. The description indicates the DS3 needs to be channelized. Question: is there an option to change the DSX3/CHNL to accept a non-channelized signal, if not, is there a card that can do the conversion that I am missing in my research?
