DISA CO-to-CO
Description
The DISA CO-to-CO (or Conference) option on the CO line governs a DISA caller’s ability to
access other outside lines. CO lines must have DISA CO-to-CO enabled to allow a DISA caller
to establish an outgoing CO-to-CO connection. This allows for specific CO line access
restriction on DISA calls. A station with Conference enabled can initiate a conference on CO
lines regardless of the CO line conference marking.
The CO line conference flag affects a DISA caller’s ability to access outgoing CO lines as
shown in the following table:
Programming Steps

2. Enter a valid number for the range of lines being programmed. If only one line is being
