Description
local telephones. Minimization of switch resource consumption at each remote site allows one
IPE shelf to support up to eight remote sites. If fewer than eight sites are needed on a particular
shelf, the remaining card slots may be used for local telephones.
MCR consists of three circuit packs: two at the local site, the Local Mini-carrier Interface card
( LMI) and Local Mini-carrier Extender card ( LMX); and one at the remote site, the Remote
Mini-carrier Interface card ( RMI). At the local site, the LMI emulates two standard IPE line
cards and can interface to the remote site through either one or two T1 carrier links. Up to three
LMXs may be added to the LMI to increase the number of telephones serviced at the remote
site. Each LMX, a double-wide circuit pack, remote two additional line cards. A maximum of
eight line cards may be remoted by one Mini-Carrier Remote system.
At the remote site, MCR uses the existing cabinet and power supply, standard IPE line cards,
and the RMI. The RMI is inserted into the core processor slot of the cabinet. This allows
customers with a system at the main location and smaller locations, to upgrade the smaller
sites to remote sites while protecting the bulk of their investment (cabinets, power supplies,
line cards, cabling, and telephones). The MCR system supports Extended Digital Line Cards
(XDLCs), Extended Universal Trunk cards (XUTs), and Extended Message-waiting Line Cards
(XMLC) at the remote sites.

Objectives

MCR's objectives are to provide:
• a cost-effective method for remoting digital telephones, analog (500/2500-type) sets, and
analog trunks from a local switch,
• remote survivability during link failure,
• fractional T1 use,
• increased availability of superloop network card slots (MCR uses no additional network
cards).

Compatible systems

MCR is compatible with any system that can support an Extended Digital Line Card (XDLC),
Extended Analog Line Card (XALC), Extended Message-waiting Line Card (XMLC), or
Extended Universal Trunk (XUT) circuit pack.
