Long-Distance Control Table

This table controls the level of authority of an outgoing call through FXO.

If Level 0 (the highest level) is set to prohibit dialing any number started with prefix 0204, then any level

below 0 (including Levels 1 to 5) is also prohibited.

If Level 1 is set to prohibit dialing any number with prefix 0, then any level below 1 (including Levels 2 to

5) is also prohibited. Since Level 0 is not restricted to any prefix, therefore at level 0 users can dial a

number with the prefix 0.

Note: Downward Restriction —If the users at a higher level cannot dial a number with a certain prefix,

then users at lowers level also cannot dial a number with the same prefix.

This table handles any exceptions to the long-distance call table.

According to the Long Distance Control Table, users at Level 0 are prohibited to dial a number with the

prefix 0204. But, if the number 020488988 is set in the Exception Table as above, then users could then

dial this number.

Note: Upward Opening —If the users at a lower level can dial a number with a certain prefix, then the

users at higher levels can also dial a number with the same prefix.

CPT/Cadence setting parameters serve as the basis of an FXO interface to determine whether

or not a PSTN-call receiving party has hung up the phone. If the following parameters differ from

the parameters of the actual assigned lines, it could cause the FXO to continue to engage a line.
