I have found a way to do it I believe here , they do it all the time with T1 and used to do it with ISDN , just no one except us special people use it anymore

,, yes it requires a Cisco modular router or lucent super-pipe , Cisco has a 4 port ISDN card , you can buy them on ebay for 8-10 dollars each
Cisco NM-4B/U 4-Port ISDN BRI Network Module w/ NT-1
and you configure Multilink PPP and a dialer interface
I'm curious since some dial up ISP's pop the second channel already is their RAS server set up to do that already ??? and would they do 4 channels ???
I have found one ISP Millenicom that says they will do as many as I want for 10.00 month each 64 k channel so for 256 k its 40 a month for the isp
anyone tried this before ?? I,m thinking on taking the dive
