MTNL Broadband: Bridging Two Internet Connection

i have following connection

1 MTNL 2 Mbps NU
2 Nivyah 4 Mbps Unlimited

now i want to bridge this two connection. since one is DSL and others is LAN can i bridge this two connection together.

If your answer is YES then How to do it?
If your answer is NO then why?

can this possibly done with the turning mtnl connection to bridge mode or do i have to modifies Nivyah Setting.

Please Help Me guys.

there are load balancing routers which can do this , do a google search

Speeds won't add up. use Load Balancing router to keep internet always on ( If one ISP fails the other will work )

hmm if you have gigabyte motherboard with teaming inbuilt

Well that too ..D-Link 4-Port Load Balancing Router
"One of the main differentiators the DI-LB604 has from most routers is its dual WAN ports. With the ability to connect up to two Internet connections, the total available bandwidth doubles in capacity and therefore provides a tremendous increase in network efficiency and user productivity. Dual WAN ports also provide a fast-acting failover response mechanism; if one Internet connection goes down, the other automatically takes control to ensure continuous network uptime."

capacity will double if multiple download streams are used..can be done with linux with IPtables , can also be done in windows..but rule remains--single download stream will use either channel but not both simultaneously

i m ready u use Dual WAN router. but how to combine nivyah and mtnl since one is worked on dsl whether another is on LAN. can a load balancing do this.oris there any kind of program that assign specific connection to specific software.
