TECHNICAL MANUAL
MMC 410:
DESCRIPTION:
Enables the system to have Direct Inward System Access (DISA). Because there is a possibility that
unauthorised calls may be made via DISA, safeguards have been included. The Customer must be made
aware of this possibility. DISA can lock out when a predetermined number of invalid consecutive calls are
attempted. Callers will then receive error tone until the programmable timer has expired. The ∗ key may be
used to initiate new dial tone while in a station to station call. The # key may be used to terminate the DISA
call and disconnect the Trunk. Only one outgoing Trunk call is allowed per DISA call however multiple
intercom calls are possible.
