Bandwidth: Bandwidth setting takes effect only when the CBR is selected. The
maximum available bandwidth is from the upstream data rate of ADSL status
page.
ENCAPSULATION: Selection follow as Table-1 Configuration
BRIDGE: Enabling bridge mode will place the unit into Transparent bridge mode (like
a Ethernet ADSL modem) to use this mode you should also set your WAN type to
a Bridging option (e.g RFC1482 Bridge using LLC).
IGMP: IGMP relay/proxy specification and environment:
Support IGMP proxy/relay function for ADSL modem, based on the following
requirement and case:
On CO side, there must be at least one IGMP querier (router) present. IGMP
querier will send IGMP query packet. The ADSL modem is responsible to relay
these IGMP query to Ethernet.
End-user multicast application device send IGMP report while receiving IGMP
query or being activated by user, the ADSL modem should be responsible to
proxy (that is, change source IP to ADSL modem’s WAN IP) the IGMP report to
ADSL WAN side, include all PVCs. The same case is for IGMP leave packet.
Not necessary to relay multicast routing between two ADSL PVCs or two
interfaces in LAN side.
Special purpose multicast packet (such as RIP 2 packet) should run without
interference.
