Remote Mini-carrier Interface card description

The Remote Mini-carrier Interface plugs into the core processor slot and controls up to eight
standard IPE line cards
T1
The T1 interface is capable of driving 655 feet without a repeater. A CSU is required for
connection to the Public Switched Telephone Network (PSTN).
Processor
The 68000-based processor controls all on-board functions, all RMI operation and steers the
proper T1 timeslots to each DS-30X channel. The microprocessor has its own EPROM and
RAM for program and data storage. See the firmware section for more information on the
operation of the processor.
CardLAN
The cardLAN interface is used to provide self-test and maintenance information and to poll all
eight line cards.

Engineering guidelines

All LMIs must reside in the same IPE shelf or cabinet as their associated LMXs. Preferably,
the LMI should be placed in slot 0 or 9 (NT8D37 shelves) or slot 1 (all others). If LMXs are
required, the first LMX should be placed in the slot immediately to the right of the LMI. Additional
LMXs are placed next to the first LMX. Grouped in this way, the cards may be randomly placed,
but each card requires two consecutive card slots and each group may not be split between
multiple IPE shelves.
