Figure 1: Mini-Carrier Remote (sample configuration)
Product description
MCR remotes digital telephones, analog telephones, and analog trunks from a local switch.
The system is modular in that the local site uses one Local Mini-carrier Interface card (LMI)
and up to three Local Mini-carrier Extender cards (LMXs). At the remote site, a single Remote
Mini-carrier Interface card (RMI), connected via one or two T1 carrier links to the LMI at the
local site, controls up to eight standard IPE line cards.
The LMI and LMX are double-wide cards, each of which occupies two adjacent line card slots.
They consist of a motherboard with circuitry and a small daughterboard that connects to the
DS-30X interface of the adjacent slot. The RMI is a single-width card that fits into the slot
labeled 0 or CPU in the cabinet.
The system may be configured as if each slot occupied by an LMI or an LMX was occupied
by one of the following standard IPE line cards:
• Extended Digital Line Card (XDLC)
• Extended Universal Trunk (XUT)
• Extended Analog Line Card (XALC)
