DVG-3016S/3032S User’s Manual Long-Distance Control Table

D-Link Systems, Inc. 41

3-16 Long-Distance Control Table

This table controls the level of authority of an outgoing (transit out) call that is dialed through FXO and

diverted to PSTN, as below:

Descriptions:

y Digit strings in this table are prefixes that the gateway will check on dialed numbers in transit out calls.

y This table is used to prohibit dialing any numbers started with specified prefixes.

y 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) are also prohibited.

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

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

a number with the prefix 0.

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

then users at lower levels also cannot dial a number with the same prefix.
