The cover sheets of a J-drawing contain a wide variety of
important engineering and ordering information. The important
parts of the cover sheet are described below. Item numbers,
below, refer to those on the typical one page cover sheet
displayed in Figure 3-5.
(1) Title Block: This contains the official drawing title,
including the input and output, if any. The title is not required
for ordering purposes. Also included in the title block are the
J-code and the issue number.
(2) J-code: This number must be included in the order exactly as
shown on the drawing. It is always followed by at least one List
number when describing an orderable piece of equipment. On its
own, the J-code refers to either the drawing itself or, in generic
terms only, the product.
(3) Issue number: Each sheet of a drawing has its own issue
number, which changes whenever anything is changed on that
sheet. The issue number of the first cover sheet changes
whenever any sheet in the J-drawing is changed. The issue
number of the cover sheet is called the drawing issue.
The drawing issue number is one mechanism used to distinguish
between vintages of the same product. Ordering information
may or may not change when a J-drawing is reissued. The
drawing issue must agree with the vintage of product available
from Lucent Technologies. Reissued drawings are sometimes
released prior to actual factory availability to provide time for
engineering and order preparation. Consult your Lucent
Technologies Account Executive for assistance with issue
number coordination.
(4) Sheet index: The index lists the numbers of all sheets in the
drawing and their respective issue numbers. Some drawings
have sheets numbered 1, 2, 3, etc. Many, including the example
shown, are divided into A-, B-, C- and D-sheets. The A-sheets
are the cover sheets and are numbered A1, A2, A3, etc. The
