Change/Display Telephone Number (chtn/dstn) Commands
This command was changed to support two local phone numbers for ISDN DBMs (ISDN DBM and DBM-I).
The new fields are as follows:
Local number 1
For the first local telephone number, this field accepts 36 characters with the same character set as the
non-ISDN DBM single local number.
Local number 2
For the second local telephone number, this field accepts 36 characters with the same character set as the
non-ISDN DBM single local number.
The phone number format (one local phone number) for non-ISDN DBM devices did not change.
