Ethernet Ports mapped to different SHDSL bonded groups
In this configuration, two independent Ethernet ports are connected to
different bonded SHDSL groups. This configuration operates as two Ethernet
extenders in the same physical unit. This feature allows for transparent LAN
services. It could be possible for Company A to use Ethernet port 1 and
Company B to use Ethernet port 3. With features such as Plans, the traffic
from each company would be separated. A better solution could be to use just
two units. Then the data is physically as well as logically separated.
Scenarios
This section provides details on possible usage scenarios for the EtherXtend
device:
• Endpoint-to-Endpoint on page 36
• Endpoint-to-Multiple DSLAMs on page 37
• Multiple Endpoints to Multiple Cards on a Chassis on page 37
Endpoint-to-Endpoint
The simplest scenario is a pair of EtherXtend devices acting as endpoints. his
pairing is where an explicit endpoint is directly connected to another explicit
endpoint. This topology is known as back-to-back mode. The following figure
details this.
