Multiple endpoints to multiple cards on a chassis

CO mode with subtened devices, page 32
The basic scenario is a pair of EtherXtend devices acting as endpoints. This
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.

This scenario enables the most subscribers. This scenario is multiple
EtherXtend endpoints connecting to multiple SHDSL cards in a chassis. Each
card has 24 ports and can connect to multiple endpoints on the subscriber side.
The following figure shows three EtherXtend endpoints connecting to a
containing three SHDSL cards. Each of those cards connects to three
subscribers side EtherXtend endpoints, each with four ports.
