6. Does the VC-based multiplexing perform better than the LLC-based
multiplexing?
Though the LLC-based multiplexing can carry multiple protocols over a single
VC, it requires extra header information to identify the protocol being carried
on the virtual circuit (VC). The VC-based multiplexing needs a separate VC for
carrying each protocol but it does not need the extra headers. Therefore, the
VC-based multiplexing is more efficient.

7. How do I know the details of my ADSL line statistics?

You can check it in Web Configurator, Advanced Setup,
Maintenance -> Diagnostic -> DSL Line -> DSL Status:

8. What are the signaling pins of the ADSL connector?

The signaling pins on the P-660HNU-Tx's ADSL connector are pin 3 and pin 4.
The middle two pins for a RJ11 cable.

9. What is port binding?

More and more Telco/ISPs are providing three kinds of services (VoIP, Video
and Internet) over one existing ADSL connection.
 The different services (such as video, VoIP and Internet access) require
different Qulity of Service.
 The high priority is Voice (VoIP) data.
 The Medium priority is Video (IPTV) data.
