Preface
This registry contains the predefined values for various maintenance operation parameters.
A copy of this registry (current as of that date) can be found in Appendix A of the MOP architecture spec. These values are referenced in the interfaces and in the message definitions.
Code assignments used in Digital products under development are not shown here. Such assignments will be included in revisions of this document as products are released. All values
that are not shown as assigned in this document are reserved for future use and may be assigned at a later time.

Appendix A
Predefined Values

This appendix contains the predefined values for various maintenance operation parameters.
These values are referenced in the interfaces and in the message definitions. Each parameter
has a description to be used in the interface calls and an actual value to be used in protocol
messages.
New values are defined on an as needed basis. Any values not shown are reserved for use by
Digital. Values are listed in decimal.

Note:
Note on the assignment for the DELQA: the primary assignment is 37. Device
code 31 is used in early DELQA devices when used on PDP-11 systems, in the
“Request Program” message only. Later revisions of the DELQA use code 37
throughout. Software shall treat codes 31 and 37 as equivalent.
Note on the assignment for MicroVAX 3300 integral CSMA/CD comm link:
there is a specific assignment for this device (61, mnemonic “MF2”). This code is
used by the boot ROMs. Operating system drivers treat it as equivalent to the
MicroVAX 2000 integral CSMA/CD comm link and use the code assigned to that
device (39, “SVA”).

Note that these codes are not the same as the “Circuit Type” codes used in the management
interface, which are defined in Section 5.4. To simplify the mapping between these two encodings, new values for Circuit Type and Data Link Type will be assigned such that the following
algorithm applies:
IF DataLinkType ! 10
THEN CircuitType := LookupTable[DataLinkType]
ELSE CircuitType := DataLinkType – 5
