Mini-Carrier Remote
Description, Installation, and Maintenance
Local mini-carrier remote extender card description
The Local mini-carrier remote extender card (LMX) is a circuit pack residing
in any two consecutive IPE card slots normally used for IPE circuit packs.
The LMX consists of a motherboard and a daughterboard. The motherboard
is a standard IPE-sized circuit pack with a double-wide faceplate. The
daughterboard is a small circuit board that picks up the DS-30X bus
connections from the adjacent card slot. The daughterboard mounts to the
motherboard through 5 standoffs.
DS-30X Interfaces
The two DS-30X interfaces and a MicroLink interface are connected to the
LMX’s second card slot’s 25-pair connector located at the back of the IPE. It
interfaces to the LMI through the LMI/LMX Multi-I/O cable assembly
(NT5D86), see Figure 6 on page 18.
Signaling Interface
The Signaling Interface block provides an interface between the signaling
channels on the DS-30X and the processor. Signaling bytes are extracted
from both DS-30X interfaces and sent to the processor. The processor also
sends signaling messages into the DS-30Xs.
Processor
The processor is a 68000-based processor that controls all on-board
functions. The processor controls all LMX operation. The microprocessor has
its own EPROM and RAM for program and data storage.
CardLAN
The cardLAN interface is the same as that of an IPE line card, providing
self-test and maintenance information. The cardLAN interface circuitry
responds to both card slot addresses, acting to the switch as two independent
circuit packs. The circuit pack responds to all cardLAN messages sent to both
card slots. In the event that the circuit pack has a failure, both card slots
indicate the failure.
Remote mini-carrier remote interface card description
The Remote Mini-Carrier Interface, see Figure 10, plugs into the Option 11
core processor slot and controls up to 8 standard IPE line cards.
