Along with Directory Number Expansion (DNXP), Call Detail Recording

(CDR) records to accommodate the increased digit field lengths. Call Detail
Recording (CDR) package 4 and Directory Number Expansion (DNXP)
package 150 are required for CDRE.
Operating parameters
The number of DNs that can be configured is limited by the available
protected data store in the system.
DNXP does not enhance existing feature capability other than allowing an
internal DN with up to seven digits.
If DNXP is equipped, the system communicates with any attached Auxiliary
Processor (AUX), except ACD-D, in a new message format containing
expanded DN fields. Therefore, the respective Auxiliary Processor (AUX)
software must be upgraded to handle longer DNs in new messages.
