The DISA feature allows an outside caller to have direct access to intercom calls. System pro-
gramming is required. See “#10 OGM Recording” on page 22 and “#24/#78 Call Incoming
Mode Selection (Day/Night)” on page 26.
Keep the following conditions in mind:
• When a caller enters the second digit of an extension number (1 through 6) during the mes-
sage, he/she can reach the extension directly.
• If the call is not received, the assigned extensions will ring. See “#04/#74 CO1 Ringing
Assignment (Day/Night), “#05/#75 CO2 Ringing Assignment (Day/Night)” on page 20 and
“#60 DISA Ringing Time” on page 27.
• If the caller enters 7, 8, 9 or 0, or enters nothing, the assigned extensions can receive his/her
call. See “#04/#74 CO1 Ringing Assignment (Day/Night), “#05/#75 CO2 Ringing Assign-
ment (Day/Night)” on page 20.
• Any calls from a rotary phone will be received by the extensions assigned in the programs
