Figure 5. MASI domain of one DEFINITY ECS 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 DEFINITY ECS 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
DEFINITY ECS. 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 established, DEFINITY ECS informs the
MMCX of its node number.
■S1 — DEFINITY station.
