Overview
This Integration Technical Note (ITN) is written for dealers who are experienced
with OneBox UM
®
and are familiar with its procedures and terminology. It also
assumes that you are familiar with the features and programming of the NEC
NEAX 2000 IVS or NEC NEAX 2400 IMX telephone system.
This document describes how to integrate OneBox UM with a NEAX 2000 IVS
or NEAX 2400 IMX telephone system using the Feature 2 application of the
NEC Message Center Interface (MCI). The NEAX MCI integration is an
outband datalink integration. The MCI link is an RS-232C serial data connection
between the NEAX and OneBox, which is used for sending calling- and called-
party information to OneBox. Analog station ports programmed into a UCD
hunt group and connected to OneBox voice ports are used for voice and DTMF
signaling between the caller and OneBox. Incoming calls to OneBox are directed
to the UCD pilot number, the UCD reports the calling information to the MCI
software, and a data packet with call type information is sent over the MCI link,
while ringing is sent to the associated analog port. OneBox matches the data
packet with the ringing analog port and answers the call with the appropriate
dialog. Message-waiting indicator (MWI) operation is also performed through the
RS-232 serial link.
Use this document in conjunction with the Installing OneBox and Administering
OneBox guides and with the OneBox online help system.
