Generally, you want the digium cards to have a high enough latency value on the digium cards that it can transfer one ms worth of audio in one burst (8*numchans bytes). You also want other cards to have low enough latency timers to grant the digium cards access to the bus soon enough, typically a fraction of a ms. See http://www.reric.net/linux/pci_latency.html.
