Installation and configuration
P0914209
Standard 3.00
April 2000
Note: Ringing frequency selection is made with a three-way switch
located to the left of the 4-position DIP switch at the top of the power
supply. Typical North American setting is -150 V, 86 Vrms, and 20 Hz.
System configuration
The configuration and administration of the MCR at the Meridian 1 local site
are identical to the standard Meridian 1 configuration and administration and
do not require special considerations.
However, there are some initial setup functions that must be considered at the
local and the remote sites. These functions are administered over the MMI
port connected to a terminal or a TTY at the local or remote site.
Configuring the remote MMI terminal port
The MMI port can be configured in the SDI or the MMI mode. When the
MMI terminal is in the SDI mode, you can perform system administration
tasks from the local or the remote site. When the MMI terminal is in the MMI
mode you can:
•
perform mini-carrier functions such as display status, logs, performance
information, history, and messages,
•
enable or disable alarms,
•
clear errors and logs,
•
set performance parameters, and
•
specify tests.
Host SDI mode
In the Host SDI mode, a terminal is connected to the MMI port (P5 on the
RMI Multi I/O cable) at the RMI. This terminal becomes the Meridian 1
maintenance and service change TTY. At the local site, the LMI connects to
the MMI port (P5 on the LMI Multi I/O cable) and to an SDI port (P6 on the
LMI Multi I/O cable) of an SDI card.
For the MMI port at the RMI to be able to communicate over the SDI port
connected to the LMI, the interface characteristics must be the same.

Speed is set at the factory to 9600 bps, but is DIP switch-configurable to
2400 bps using SW3, position 5.
