Vadim,
Each B channel has it's own SPID. If you wish to use both B channels, you
need to list both spid1 and spid2 under your BRI interface. There are a
couple more things you must do in order to use both B channels: you must
list both spids for the remote end (using dialer-string or dialer map
statements), you must use "ppp multilink" command, and you must set a
load-threshold for when to bring up the second link (you can use "1" percent
as the threshold if you want both B channels to come up immediately).
HTH, Kym
