General Application Notes
P-873HNUP-51B supports ADSL/VDSL bonding, user can use two DSL line to connect
to P-873HNUP-51B, and it would have double bandwidth for upstream.
We use P-873HNUP-51B as the sample for WEB GUI and configuration.
Why use P-873HNUP-51B?
High Speed Internet Access
The P-873HNUP-51B is a VDSL\ADSL\Ethernet gateway supporting the
downstream transmission up to 1Gbps and upstream transmission up to
1Gbps.
Quality of Service (QoS)
The P-873HNUP-51B with Quality of Service features ensures that the Triple
Play Service keeps the high quality delivery in high speed Internet access.
PPP over Ethernet
Since the PPPoE will benefit both Telco and ISP, the P-873HNUP-51B shall
implement this feature and be tested well with the PPPoE servers.
Multi-NAT
The NAT provides system administrators an easy solution to create a private
IP network for the security and IP management. Powered by NAT technology,
the P-873HNUP-51B supports the complete NAT mapping and most popular
Internet multimedia applications, such as NetMeeting, MSN Messenger,
Skype, ICQ, IPTV, QuickTime, Real Player (RSP/RTSP), VoIP SIP ALG, etc.
