transparent for both tagged and untagged Ethernet frames. This allows
services like Home office, where the IP address is assigned from the DHCP
server at the office premises. Another service example is a VLAN for Home
interconnections where a group of end-users wants to interconnect their
LAN networks.
Figure 63 on page 102 shows the VLAN service for Home Office and Home
interconnection.

Interconnection
When LAN-to-LAN transparency is used, all filtering in the IP DSLAM for
the subscriber is disabled, and broadcast is allowed. If any filtering or
protection is desired, it must be done in the Edge Node or CPE.
Interconnected LAN-to-LAN end-users may be located on the same IP
DSLAM or different IP DSLAMs. They may use any mixture of DHCP
obtained and static IP addresses.
