Microcom ISPort worse for fiber POTS?

Our POTS lines come in on fiber and are changed
to analog by a "channel Bank" or "demux" on
premises.

Apparently the digital to analog conversion
impacts data speed negitively and most
users get 21 to 24 K connections.

If I buy the new Microcom ISPort modems and
plug them into my portmaster would the additional
analog to digital conversion on the modem adapter
make the connect speeds worse? Anyone have any
experience with this?

------------------------------------------
Using a channelized T-1 for POTS is too
expensive (same charge per line plus
several hundred per T-1) and since I have
many analog Microcom modems connected
to portmasers and PRI costs more per line
I don't want to go to PM3 yet.
