Description
P0914209
Standard 3.00
April 2000
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 via 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, remotes
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 Option 11 cabinet and power
supply, standard IPE line cards, and the RMI. The RMI is inserted into the
core processor slot of the Option 11. This allows customers with a Meridian 1
at the main location and Option 11s at other, 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
telephones, and analog trunks from a Meridian 1 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 XDLC, XALC,
XMLC, or XUT circuit pack. This includes Meridian 1 Options 11, 11C, 11E
21, 21A, 21E, 51, 51C, 61 61C, 71, 81, 81C, and older Meridian 1 systems
that have been upgraded with IPE modules. MCR is compatible with
Meridian 1 software release 17 and above.
