following figures depict several possible configurations.
Figure 135: 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 to 15. Once the node number is established, Avaya Communication Manager informs
the MMCX of its node number.
S1 — Avaya Communication Manager station.
