Message Waiting Indication (MWI) Interworking
With X11 Release 19, centralized message services are now provided for a
corporate network, consisting of Meridian 1 and Centrex (DMS-100)
systems. This means that a user on a Meridian 1 system can directly access
the voice message system on a DMS-100 and vice versa. MWI Interworking
allows either one of the two configurations listed below:
— The Meridian 1 system hosts the Message Center and serves both
Meridian 1 and DMS-100 users in the same customer group or corporate
network.
This configuration enables DMS-100 private or public network callers to
leave messages for subscribers on the Message Center connected to the
Meridian 1 system. The Meridian Message Center then initiates a facility
message to turn on the Message Waiting Indicator at the subscriber’s
station, located either on a Meridian 1 system or on a DMS-100 system
within the same customer group. The subscriber can then retrieve the
messages, and the Message Waiting Indicators will automatically turn
off (accomplished via a facility message initiated from the host switch to
the remote switch where the subscriber resides) when retrieval is
complete.
— The DMS-100 system hosts the Message Center and serves both
Meridian and DMS-100 users in the same customer group.
This configuration enables Meridian private or public network callers to
leave messages for subscribers on the Message Center connected to the
DMS-100 system. This configuration then functions in the same way as
the Meridian 1 system host configuration.
Note:
These configurations enable one or more Meridian and one or
more DMS-100 customer locations to be connected directly or in tandem
through Meridian 1 or DMS-100 systems to the Meridian 1 or DMS-100
directly supporting the Message Center. The connections between the
switches must be ISDN.
