The Ethernet interface is a 10/100BaseT interface that automatically
negotiates the rate. If all attached Ethernet devices support 100BaseT, the
DSL router will default to 100BaseT. Otherwise, the DSL router operates at
10BaseT.
H
The DSL router can be configured for either DIX format or IEEE 802.3 format.
When the DSL router is configured to use IEEE 802.3 format, the DSL router
uses SNAP encapsulation as specified in RFC 1042.
H
The Hotwire 6322 IDSL and the 6342 SDSL Routers each have a hub
configuration with four Ethernet connectors. The hub acts as a bit-level
repeater. There is logically one Ethernet communications interface and one
single collision domain.
H
All DSL routers have an Ethernet interface with a unique MAC address
assigned before shipping.
H
The DSL router only accepts frames on the Ethernet interface with its own
MAC address or a broadcast or multicast MAC address.
The following are the naming conventions used for the Hotwire DSL Router
interfaces:
H
e0 – Ethernet interface name.
H
d0 – DSL interface name.
H
Multiple Service Domains can be defined using network addresses and
subnet masks.
H
For both the DSL interface and the Ethernet interface, four Service Domain
IP Addresses and subnet masks can be defined.
