3 Guidance for preparation of detail specifications
lt is necessary to keep the transmission characteristics indicated in the relevant sectionalspecification for the category number(3 or 5) and the characteristic impedance.
NOTE When a characteristic does not apply， then NA (for Not Applicable) may be entered in the appropriatespace.
When a characteristic applies but a specific value is not considered necessary, then NS (for Not Specfied shouldbe entered in the appropriate space.
