Description
P0914209
Standard 3.00
April 2000
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 processor is a 68000-based processor that controls all on-board
functions. The processor controls all RMI operation and steers the proper T1
time slots 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 Option 11 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 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.
