7.3 GPON encapsulation method port (GEM-Port)
GEM is a data frame transport scheme used in GPON systems which is connection-
oriented and supports fragmentation of user data frames into variable-sized trans-
mission fragments. One or more GEM-Ports on the other hand are a logical
gateways for specific user data flows that are assigned to a specific T-CONT. So
it is possible to differentiate between user data within the same service that is
represented by a T-CONT.
