VPI/VCI Detect
VPI/VCI detection is a selectable function.
On
A port with VPI/VCI Detect on will automatically "snoop" the line to determine the
VPI and VCI settings of the remote ADSL modem to which it is connected and set
itself accordingly. If no ATM cells are detected (at any VPI/VCI setting), the port will
default to VPI 0 and VCI 35. Thereafter, once it does detect ATM cells from the
remote ADSL modem, it will reconfigure VPI and VCI to the same settings at which
the ATM cells from the remote ADSL modem were detected.
Off
A port with VPI/VCI Detect off will default to VPI 0 and VCI 35 unless the port was
previously set at VPI/VCI Detect on and had already detected the VPI and VCI
settings of the remote ADSL modem. In this case, turning the VPI/VCI Detect
function off will lock in the previously detected settings until, or unless, the VPI and
VCI values are altered manually.
Default: On
