Another useful advantage without the latency tradeoff is to read a full span or card every 1ms (or whatever sane interval) and chop up the bytes in userland. The latency argument dies if you are bridging to voip, so if you can handle bridging the tdm to tdm channels in kernel space, you could easily get away with 10ms reads to user space as well.

Hi, Got your point. In between: I see more in Jan's argument. 48x30 bytes = 1440 bytes, which is an interesting size for full span E1. --HPS
