Drawer state display
A list of the codes that display line drawer states at the MAP terminal appear
in table "LCM drawer states". This text uses standard abbreviations instead of
code to describe line drawer states.
At the LCM level of the MAP display, the state of the drawers appears below
the state of the LCM units. The drawers are numbered from 0 through 19. The
numbers are grouped in pairs to show that the numbers share the same bus
interface card (BIC). The drawer state numbers normally interface a different
processor, odd or even. An example of drawer state appears in the following
