order number
A customer-level number that can be used to order a Bay Networks product.
parent assembly
The assembly to which a part or sub-assembly reports, as determined by how
the BOM is structured. For example, the parent assembly number of a PCB is
the board number.
part number
A number in SAP, or in the ECO/PCN/BOM system, that specifies a particular

PCB vendor
The PCB manufacturer.
PCN
Prototype Change Notification—the process of notifying manufacturing that

descriptions of any parts that might have changed, etc.
prototype
A design-in-process part that has not been released for production.
PWB
Printed wiring board, also known as PCB.
qualify
The process by which component engineers approve the incorporation of
particular parts from specific vendors.
reference designator
Refdes—an electronic component identifier used on schematics, layout
drawings, etc.; for example, R1 through R
n
might designate where resistors
might go, and C1 through C
n
might designate capacitors. U1 through U
n
are
used for unspecified parts.
REL
The status of a part that has been released via an ECO into production.
report to
One part reports to another when the other includes that part in its BOM
structure. See
parent assembly
.
revision register
