I have Airtel broadband and a Tata broadband connection. i have around 50 PCs connecting through an airtel broadband connection.
Both are dsl connections with my phone line going into dsl modems and an Ethernet cable going from dsl modem directly into a switch. Currently, only airtel connection is connected with static IP on my private lan and using the airtel ISP DNS servers as DNS IP address and the default gateway is 192.168.1.1 (IP add. of the dsl modem). All PCs are connected in a work group.
When in full use, my users complain of certain web pages are not opening. When I ping Internet addresses like Yahoo or Google I get 2 reply packets and 2 lost packets. I suspect that a single broadband connection is not able to sustain 50 simultaneous downloads/browsing.
Is there any device which connect to both DSL and make one line so that its give me high speed simultaneous browsing. Help needed urgently. Thank you all to those who reply.

Packet loss tells me that something is malfunctioning somewhere, likely a switch or the modem itself. Depending on what you're doing, a DSL connection should be adequate for 50 users just surfing the Web: I have several clients on standard business class DSL connections (5Mbps down, ~800Kbps up) with ~100 users using the Internet for standard Web surfing and email and performance is fine.
I do find that I regularly swap out DSL modems, regardless of manufacturer: they just seem to be cheaply made, get pretty hot, and die eventually. Might be worthwhile as a quick test to swap in another DSL modem.
If you're a heavy Internet user (lots of downloading/uploading of large files, etc.) and with two DSL connections, I'd recommend getting an edge router that can do load balancing/failover and possibly Quality of Service (QoS): Netgate sells ALIX kits with pfSense (Open Source) firewall, which has "enterprise" features for ~$200 USD. Best bang for the buck for a firewall I've seen. With that configuration, you can even setup policy-based routing to route certain traffic out one connection primarily (say, core server services like email, DNS, etc. get routed out through DSL #1, web surfing out #2), while failing over when it's down.
