Abstract
An apparatus grouping data units for optical network units into groups of Encapsulation Method, EM, frame(s), wherein a respective group of EM frame(s) include data units addressed to a respective subset of ONUs, generating, based on the groups of EM frame(s), a Framing Sublayer payload including at least one specific frame, wherein, the specific frame includes a length indicator determined in relation to the length of the group(s) of EM frame(s) that is(are) directly following the specific frame and is(are) addressed to at least one subset of ONUs; instructing the ONUs assigned to at least one of said at least one subset to process the EM frame directly following the specific frame, and instructing the ONUs not assigned to the at least one subset to process the EM frame that is indicated by the length indicator of the specific frame; and transmitting the Framing Sublayer payload to the ONUs.
