Toll Restrictions
Parameter Function
46 Don’t allow 9 as the first telephone number digit = 0
Allow 9 as the first telephone number digit = 1
47 Don’t allow 1 as the first telephone number digit = 0
Allow 1 as the first telephone number digit = 1
48
Don’t allow 0 as the first telephone number digit = 0
Allow 0 as the first telephone number digit = 1
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.
446-449 Toll restrict prefix #1. Valid range = 0-$D (1–4 digits).
450-453 Toll restrict prefix #2. Valid range = 0-$D (1–4 digits).
454-457 Toll restrict prefix #3. Valid range = 0-$D (1–4 digits).
458-461 Toll restrict prefix #4. Valid range = 0-$D (1–4 digits).
462-465 Toll restrict prefix #5. Valid range = 0-$D (1–4 digits).
466-469 Toll restrict prefix #6. Valid range = 0-$D (1–4 digits).
470-473 Toll restrict prefix #7. Valid range = 0-$D (1–4 digits).
474-477 Toll restrict prefix #8. Valid range = 0-$D (1–4 digits).
478-486 1st 9-digit phone number/prefix excepted from toll restrictions.
487-495 2nd 9-digit phone number/prefix excepted from toll restriction.
496-499 4-digit emergency access number excepted from toll restrictions.
500 Maximum phone number length allowed.
Valid range = 1–20. If this parameter is greater than 20, an entry of 20 is assumed.
