FID RULES/CONSTRAINTS:
  1. This feature allows the network to recognize which terminals are capable of receiving periodic test calls and to recognize those terminals requesting confirmation of each data message sent.
  2. T and F order types are prohibited for Access Service application.
  3. TL1
    When the DLC FID appears, the Logical Channel Layout (LCL) FID must appear on the same logical line.
  4. SERIES AND RANGE ENTRIES - PROCESSING
    Series and range processing is not appropriate on this FID,  since the USOC logical line will never carry a quantity greater than 1.
