Up to eight different prefixes of up to four digits each may be restricted. Additionally,
up to two numbers or prefixes of up to nine digits each may be specifically allowed, even
though they contain a restricted prefix (such as 1411 for information, etc.). One other
number or prefix of up to four digits may be specifically allowed. When a number is
determined to be restricted and not stored as an allowed number, the patch disconnects
the phone line.
For all the remaining parameters of this section, unused digits must be filled with FF (hexadecimal FF).
To completely disable an entry, program all its digits to FF.
