Nortel option 21 PBX to MCR via fiber

[dsturgeon]

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 found a note in the manual about the NT7R93AA adapter and how it 'is only necessary for connection with the NT7R93BA adapter in a direct cable connection that does not use a T1, thus not using a CSU/DSU'. So, it looks like it can be done I just need to find theses adapters.
