Figure A-3.Address Ranges When Dealing with a DCS Environment

Legend:

‘‘Dial Plan’’ indicates the extensions in use at the switch. These are both AUDIX subscriber extensions and non-subscriber extensions.

‘‘Address Ranges’’ indicates the extensions assigned on the system : translation :

machine : audix/amis/call delivery form for the local system.

The purpose of Figure A-3 is to show that the address ranges assigned at AUDIX system 3 should include the dial plan of the entire DCS environment (Nodes 1 through 3), even though AUDIX system 3 serves only Node 1. The reason for this is that a caller at Switch 2, after unsuccessfully reaching a ‘‘live’’ person at Switch 3, cannot transfer out of the AUDIX system to a person at Node 2 or Node 3 unless the extensions at those nodes appear in the address range(s) along with Node 1’s.

Figure A-3 also shows how multiple ranges and duplicated ranges are used as opposed to using 0000 – 9999 at all systems. Using 0000 – 9999 would require memory allocation for extensions that do not exist.
