For an introduction to visp.net's bonded DSL offer, please take a look at this NOC Nuuz article. Bonding two DSL circuits requires a router such as a Cisco 1721 or 1841 that supports ADSL WICs and a software version of Cisco IOS that supports the ADSL WICs and Multilink PPP over ATM. An example configuration for MLPoATM with Cisco 1700 series and WIC-1ADSL is below. This is for the CPE (customer) side of the link. Bonding more than two DSL circuits would require a 3600 series Cisco router.
Q: Will the Actiontec High Performance IPTV routers/gateways work for the bonded DSL service? A: No, these modems use ADSL2's G.Bond-ATM protocol, which is an ATM layer (layer 2) bonding solution for ADSL2 only. ADSL2 is not currently offered by CenturyLink (Qwest). Our bonded solution is at the PPP layer (Multilink PPP over ATM), which these modems unfortunately do not appear to support.
