I have two locations connected with 512K Radio Links, On head office we have Cisco 2651XM and on branch side we have Cisco 1751, both are connected and working fine,We are already using internet via 512K Radio Bridge link with ISP in headoffice, now we want to add ADSL and ISDN link also for internet access in case our 512K radio link to ISP goes down.Our basic requirement is that 512K ISP Radio Link,ADSL Internet Link and ISDN link should connect directly on the Cisco 2651XM, so that it should provide us load balancing and backup(reliability in case one link down), Our Cisco 2651 has two Fast Ethernet, 1 WIC-T2 and one ISDN S/T module.our WIC-T2's serial 0/1 already connected with radio modem toward the Branch office and one serial interface is free.
Please provide me the best solution with detail.
