■ MASI signaling link — ISDN D-channel used to transport a new ISO
protocol called the MASI protocol between the Avaya MultiVantage and
the MMCX.
■ MASI terminal — The MultiVantage system representation of MMCX
terminals in a MASI environment.
■ MMCX interface — PRI interface for connecting an MMCX server to
other public, private or wide area network (WAN) switching systems or
equipment that is part of the public network. Similar to a MultiVantage
trunk group. These may include non-MASI trunks connecting the Avaya
MultiVantage and the MMCX.
■ MMCX trunk — The MultiVantage system representation of trunk or
network facilities terminating on MMCX. For purposes of MASI, they are
called “interfaces.”
Planning for MASI
Before you start to administer MASI, you should make a plan for how to do it.
Among the configurations on the following pages, there is probably one that
matches the configuration of your system fairly closely. You might want to either
write on these pages, or draw up your own configuration. It may help you if you
have already determined trunk group and signaling group numbers, unused
extensions, and so on. The following are things you need to consider:
■ Establish the dial plan on the MMCX to agree with that of the Avaya
MultiVantage. If you use Universal Dial Plan and MMCX, you may need to
make adjustments for the MMCX dial plan.
■ Find unused extensions and trunk group numbers. You need:
— one trunk group number for each ISDN-PRI connection to the
MMCX
— one signaling group number for each MASI node and an unused
MultiVantage extension for the signaling group
— one unused MultiVantage extension for the Near-End Path
Termination number for all MASI Paths to this ECS. You can use
the same number for all MASI nodes in the domain.
— two unused MMCX extensions for the nearpath and tscnum
arguments to the
chgmasi command. This is the command you use
to administer MASI on the MMCX.
