Nortel option 21 to MCR via fiber

Oct 20, 2005 2 Replies

We currently have an Meridan Option 21 switch that is connected to a mini carrier remote via T1. We are going to be bringing a GB fiber connection online fairly soon and will be removing the T1 connection. My question is what type of converters/adapters/etc would I need to keep this connection alive? According to the manual the supported framing modes are ESF and D4. It also states that B8ZS encoding must be used.



If there is a better group to post this in, please let me know.


I did find a note in the manual about using a NT7R93AA adapter if a CSU/DSU and T1 is not used. I just need to find out what to do with it and where to get it I think.
