DN chart for new 3.0 or newer systems
If your system is a brand new BCM 3.0 or newer system, the DN numbering is consecutive from
DS30 02 to 07.

1 DNs are based on the default, three-digit DN. If your system has another numbering system, make a note of your
DN ranges in the Custom DN column.
2 ASM 8 modules do not have special double density settings. However, on a PDD system, on DS30 06 and 07, only
offset 0 and 1 are available.
3 If you system is set to a 3/5 DS30 split, these DNs are not available to digital telephones.
4 Each Bus has 32 ports, numbers 0<bus#>XX (for example: 0201 is the first port on Bus #2). Ports are assigned
sequentially to each DN number. However, if you change the DN number, the port number remains the same.
