The Florz patch allows for timer slave mode, which means the buffer timers
for the NT cards are derived from (one of) the TE card(s), That way the NT
cards are always synchronized to the ISDN PSTN, which would mean that
there ir virtually nill chance of buffer over- or underruns, thus
improving call quality when crossconnecting the cards for PSTN calls...

It is not really crossconnecting, it is parallel connecting the cards, ie
all NT cards and *one* TE card have their cologne chip's pins 54 connected
to eachother, as well as all their pins 53 and 52... I have followed
Florian's tip to make connectors, so you can connect them using a cable,
rather than having them always connected.

This also allows me to test with both configurations: double master or
master/slave...

More to come...  ;-)
