At my workplace we have a router which has two WAN connectors which allow transparently combining two ADSL connections or one ADSL and one ISDN as fallback.
What's the name of this feature?

We can say Dual-WAN or Multi-WAN Routers, theses are not very specific features, you may have for example a juniper router on which you can make any port into the wan security zone and get them to failover.
Did you mean load balancing ? If yes - on SOHO routers which usually contain linux inside - by adding 2 or more default routes (LARTC)
It is a Dual-Wan Load Balancer Router. Try this link http://www.dlink.com.ph/products/?model=DI-LB604
I'd use this product without troubles.. it works for me...

When you combine T1's in the way you have mentioned, that is called bonding. On Cisco routers, you do this with a multilink interface.
