One of the characteristics of a databridge is the number of ports it supports. A

bridge port is the logical equivalent of an interface. By default, the ADSL modem

supports one local port (Ethernet interface) and four remote ports. The remote

ports are mapped on the virtual ATM connections of the ADSL line. Only the

remote ports are displayed in the table and are indicated as ADSL Port 0, 1, 2,

and 3.

This field indicates the encapsulation of Ethernet or IEEE 802.3 frames to

AAL5/ATM protocol.

The ADSL modem supports both the LLC/SNAP method and the VC MUX method

for bridged Ethernet V2.0/IEEE 802.3 PDUs. By default, this field is set to

LLC/SNAP, and the access server of the ISP or corporate network must use the

same method. If it does not, contact the ISP or corporate network administrator.

This field indicates whether the last four bytes of the MAC frames are preserved or

VPI and VCI values identify an ATM virtual connection. Because the modem

comes with preconfigured VPI/VCI values, you do not have to configure these

fields.

However, if the ISP or corporate network administrator require VPI/VCI values

different from the default values, you must enter these specific values in this field.
