Note:
If the PBX CO line is set to Point working, it will link with either a Point or Multipoint
service provided by the Network Provider.
When upgrading a Version 4 or earlier PBX with PC Programming, care should be taken
to check the DDI translation on the Version 5 data base.
On the Version 4 or earlier PBX there was no Day Night destination option and DDI
numbers were assigned to the Ports using several Program Steps
(i.e. 112; Hunt Groups, 136; Phantom Extn, 618; Extn, 619; ISDN Extn).
