             be transferred                      specified in Table 11-1.1.
             NOTE – The VCE or TCE may be involved in generating the ME to FTU-O information flow to coordinate timing and control
             parameters over multiple lines.
             *.request(parameter)              ME → FTU      Requests the FTU to send the system-related OAM data
                                                             (represented as a parameter) to the far-end FTU.
             *.confirm                         FTU → ME      Confirms that the requested data has been scheduled for
                                                             transmission over eoc or RMC and that the FTU is ready
                                                             to accept the next request.
             *.indicate(parameter)             FTU → ME      Indicates reception of any system-related OAM data
                                                             (represented as a parameter) from the far-end FTU.
             NOTE: The specified set and format of primitives shall be applied to any eoc/RMC command (denoted as *) that provides a
             transparent channel between the near-end ME and the far-end ME to convey system-related primitives.


            11.2    Management functions and procedures over eoc
            11.2.1  eoc transmission method

            The  eoc  is  established  between  the  peer  TPS-TC  management  entities  and  provides  exchange  of  eoc
            packets  between  the  FTU-O  and  FTU-R.  Each  eoc  packet  is  formatted  as  defined  in  clause 11.2.2.1  and
            carries one or more eoc messages formatted as defined in clause 11.2.2.2. The transmission protocol that
            defines eoc message exchange between peer FTUs is defined in clause 11.2.2.3.
            11.2.1.1   eoc packet format

            The eoc packet may contain one or more eoc messages. The length of an eoc packet containing  m eoc
            messages  with  the  lengths  of  P1,  P2,  …  Pm  bytes  is:  P  =  P1  +  P2  +…  Pm  +2m  +2  bytes,  where  2m
            corresponds  to  the  2-byte  control  field  per  message,  and  the  final  two  bytes  are  for  the  frame  check
            sequence. The value of P is determined by the FME. The maximum value of P is 1 024 bytes.
            The format of an eoc packet shall be as shown in Figure 11-2. Each message should have a format defined
            in  clause  11.2.2.2  and  could  be  an  eoc  message  or  an  eoc  message  segment.  Only  one  segment  of  a
            particular eoc message shall be included in a packet.
