The EU parameters
This section provides some background information on EU parameters. For detailed
information about each parameter, see the MAX Reference.
EU-RAW and EU-UI
EU-RAW is a type of X.75 encapsulation in which IP packets are HDLC encapsulated with a
CRC field. EU-UI uses the same encapsulation, but contains a smaller header that can contain
one value for packets from the caller and another value for packets from the called unit. Most
EU connections use EU-RAW.
Maximum Receive Unit (MRU)
The MRU parameter, in a Connection profile's Encaps Options profile, specifies the maximum
number of bytes the MAX unit can receive in a single packet on an EU link. Usually the
default of 1524 is the right setting, unless the far-end device requires a lower number. If the
administrator of the remote network specifies that you must change this value, enter a number
lower than 1524.
DCE address (DCE Addr)
The DCE Addr parameter specifies a value for the calling unit in the EU-UI header. The caller
needs to obtain the number you specify and configure the calling unit accordingly.
DTE address (DTE Addr)
The DTE Addr parameter specifies a value for the called unit in the EU-UI header. The caller
must use the same value for the called unit.
