I have two semi-related questions:
What do I look for in specs to identify ADSL2+ modems capable of supporting line-bonding? I can't seem to locate any clear indication of those which do versus those which don't.
Update 1: ITU G998.2 seems to be the standard relevant to ADSL line-bonding. Is that usually mentioned in the advertising of qualifying modems?
Regarding a prospective VDSL connection, the distance from the ISP telephone exchange to my home is 1.6 KM as the bird flies. Is it likely I can get near the advertised speeds of 10mbps down/5mbps up based on physics alone? The ISP have no CPEs for rent at the moment, and the market availability is close to nil, except for Asus DSL-N66U. That's an expensive modem. I want to know if VDSL can deliver at that distance befoe I buy the modem and apply for a VDSL connection. My research did not yield unambiguous answers.
Update 2: I had an ADSL2+ - 2mbps Down/0.5mbps Up - connection installed using an ISP-rented modem. The downstream SNR is in the mid-30s, while the upstream is 42 dB. The line attenuation downstream is 19.8 dB while upstream is 7.6 dB. Can VDSL viabiity of 10 down/5 up be inferred from these numbers?
