Merging two Connections

I have two Internet connections, PTCL DSL and Worldcall EVDO, I want to merge both of them. Can anyone tell me how can it be done?

please share some guide/tips.

yes they can load-balanced...... but as i mentioned in the other thread..... u cant use PTCL DSL via wi-fi and EVDO usb together...... If you use PTCL DSL via RJ-45 ethernet cable on the said machine then yes they can be load balanced.
