DESCRIPTION
This refers to the operational protocol the Prestige and the DSLAM (Digital
Subscriber Line Access Multiplexer) are using.
The standard the ISP supports determines the maximum upstream and
downstream speeds attainable. Actual speeds attained also depend on the
distance from your ISP, noise, line quality, etc.
Click this button to reinitialize the ADSL line. The large text box above then displays
the progress and results of this operation, for example:
"Start to reset ADSL
Loading ADSL modem F/W...
Reset ADSL Line Successfully!"
Click this button to display the upstream noise margin.
Click this button to display the downstream noise margin.
Click this button to display the upstream and downstream rates of your ADSL link.
Click this computer to have your device perform a Cyclic Redundancy Checksum.
The Prestige sends a sequence of bits to every block of data or frame. This is
called a frame check sequence (FCS). The receiving computer uses a
predetermined number to divide the frame. If there is a remainder, then the frame is
considered corrupted and a retransmission is requested.
Click this button to view ATM status.
Click this button to start the ATM loopback test. Make sure you have configured at
least one PVC with proper VPIs/VCIs before you begin this test. The Prestige
sends an OAM F5 packet to the DSLAM/ATM switch and then returns it (loops it
back) to the Prestige. The ATM loopback test is useful for troubleshooting problems
with the DSLAM and ATM network.
