Multichannel ISDN not working - Cisco 1603

[Piloria]

the router works fine when only using one channel (64k)is open.but when the second channel opens then the router stops sending any data until one channel closes andthen it works fine again.

Please post the configuration of your router so that we can take a closer look.

Thanks,

Your ISP probably doesn't support multilink PPP.
Remove the pp multilink line or find an isp that does. :/
