The Sangoma cards use their own zaptel compatible driver called
wanpipe, available at:
ftp://ftp.sangoma.com/linux/current_wanpipe.
They provide timing source and have some very nice optimisation
features added, amongst them:

You can choose enabling or disabling of echo cancelation per span
The cards provide HDLC in firmware (can be enabled or disabled in configuration)
You can selectively set if all spans should be hardware synchronised
to one clock or if they should use adaptive synchronisation.
THe cards can also handle a pletora of other protocols (ATM, bisync,
X.25, Frame Relay ...) completely independant of asterisk.

If you need any further details feel free to contact me.

cheers
