Appendix A. Compliance Statement
FCC Warning
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can
be determined by turning equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
l
Reorient or relocate the receiving antenna.
l Increase the separation between the equipment and receiver.
l Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
l Consult the dealer or an experienced radio/TV technician for help.
CE Mark Warning
This is a Class B product. In a domestic environment, this product may cause radio
interference in which case the user may be required to take adequate measures.
Appendix B. Encapsulation Mode
Bridged mode（RFC-1483）
RFC-1483 provides the simplest method of connecting end station over an ATM network.
User data in the form of Ethernet frames is encapsulated into AAL5-PDU for transport over
ATM. RFC-1483 provides no authentication and configuration such as would be provided
by PPP. RFC-1483 implementation supports VC multiplexing and LLC/SNAP encapsulation
in both routed and bridged configurations.
Classical IP over ATM-IPOA（RFC1577）
User data in the form of IP packets is encapsulated into AAL-5 PDUs for transport over ATM.
The fact that the user data is routed at an IP layer instead of bridged MAC layer allows the
source and destination to be on different subnets. A notable drawback of IPoA is the lack of
authentication and configuration such as would be provided by PPP.
PPP over ATM-PPPoA（RFC-2364）
The use of PPPoA is similar to IPoA. However, a PPP session is established to the remote
access server (RAS). The PPP packets are encapsulated according to RFC-2364 for
transmission over an ATM link. On the receive side, the de-encapsulation is performed. The
PPP session is terminated and the IP packets can be delivered to the end user over
Ethernet or other medium.
