Point-to-point LAN connection

...................................................................................................................................................................................................................................
The point-to-point LAN connection is used to interconnect two sites of a customer
each of which has a LAN interface. Another application is the interconnection of the
sites of two service providers that have Ethernet interfaces.
Some dedicated SDH bandwidth is allocated to the connection between both end
points. Virtual concatenation allows the operator to assign a customized SDH
bandwidth. Such an application can cost-effectively be realized with 1643 AM / 1643
AMS using the X8PL option card which provides the GFP and LAPS Ethernet
mapping schemes and the LCAS protocol (please refer to
"Ethernet mapping schemes" (p. 2-15)
(LCAS)" (p.
