2121 vs 2123H

[pyonc]

Can you use 2123H as a replacement for 2121 in 4343?
If not, what are the available options? I hear 2122H is a better one, but almost impossible to obtain.

HI pyonc,
I think You can use it, but some network tweaking would be necessary .

Thanks. I don't know how to do that network tweaking, so let me stay away from it.
Any other option available? I hear E110 is the closest replacement...
