Figure 14: MASI domain of Avaya Communication Manager running on one DEFINITY
Server and one MMCX
The parts of this drawing, for MASI, are as follows:
•
Trunk 1 — This is any type of trunk connection to the public network.
•
Trunk 2 — This is the link between the Avaya Communication Manager solution and the MMCX,
and requires a TN464C or later DS1 circuit pack. You administer this link as an ISDN-PRI trunk
group, a MASI path and an NCA-TSC.
•
I1 and I2 — These are MMCX interfaces to destinations other than Avaya Communication
Manager. Administer as MASI trunks.
•
E1 and E2 — Endpoints (terminals) belonging to the MMCX. Administer as MASI terminals.
•
MMCX — Determine a node number for each MMCX server. This can be any number from
1–15. Once the node number is established, Avaya Communication Manager informs the MMCX
of its node number.
•
S1 — Avaya Communication Manager station.
