Meridian MCDN call features over PRI SL-1 lines
Besides the general MCDN features described in Understanding MCDN network features on page
532, an MCDN connection with a Meridian 1 voice mail system, also provides some special call
features, which are listed in the following table:
Message Waiting Indication
MWI allows the voice mail host system (Meridian 1) telephone that is designated to receive
messages to notify a target telephone on the Business Communications Manager of a call waiting
using the MIK and MCK message indicators on the Meridian telephones. This feature works for
both Nortel and third-party voice mail systems. Messages are received at a centralized location, to
a pre-determined telephone, where they are processed and forwarded to the target telephone.
MWI allows the user to reply or call back to the message center. The procedure for retrieving
messages is described in the Telephone Features Handbook.
The following figure demonstrates how the Meridian responds when a call is forwarded to a
Meridian Mail mailbox.
