This chapter describes and defines requirements for the NEC NEAX 2400 MCI switch integration with an INTUITY Messaging System. The chapter includes diagrams and checklists that show the configuration for INTUITY Messaging System.
To create an integrated environment between INTUITY Messaging System and an NEC NEAX 2400 MCI switch, AT&T uses an electronic box called a Switch Integration Device (SID). The SID operates as a protocol converter between the switch and the INTUITY Messaging System, converting NEAX 2400 call information into Simplified Message Desk Interface (SMDI) format and sending the information to the application. The SID does not restrict any switch features.
For the SID to perform integrated call transactions, the switch must contain a Message Center Interface (MCI) link. The MCI link provides an
All channels reserved for the INTUITY Messaging System must be administered in a Uniform Call Distribution (UCD) group. The first channel in the UCD serves as the forwarding or central number for INTUITY Messaging System subscribers. After administering the switch, all covered and forwarded calls transfer to the first channel or central number of the UCD group. If the first channel is busy, the system searches through the other members of the UCD group until the system finds an open channel. Figure
