R2MFC Media Bay Module Installation and Configuration Guide

This section provides the following information about the setup requirements for the R2MFC 
MBM:

Determine and set the Config DIP switches to the correct country code, and second dial tone 
setting for the R2MFC MBM. Predefined country codes are set by the Config DIP switches. 
Special configurations are set through the CLI. See 

 for a procedure on how to set the DIP switches for a predefined country code or how to 

create a special configuration to meet the installation needs.

The default country code setting is Mexico config 1. See 

 for a list of the available country codes, the country default 

settings, and the second dial tone settings.

Second dial tone, when turned on, generates and supplies a second dial tone to the end user, after 
the end user dials the trunk access code. The end user hears a dial tone between the last digit of the 
access code, indicating that a line was accessed. See 

 for 

a procedure on how to set the DIP switches, and configure the BCM for second dial tone to work 
properly.

Before the R2MFC MBM is installed, DS30 buses and offsets must be set by DIP switches.

 Use 

the six DIP switches on the underside of the R2MFC MBM, behind the power connector. 

The R2MFC MBM occupies two DS30 buses from the DS256 bus; however, only the first is 
actually used. Buses 1 and 8 are reserved for internal BCM communications. Therefore, the 
R2MFC MBM DIP switches can only be set to use buses 2 through 6 on a 2/6 split or buses 2 
through 5 on a 3/5 split. If there are not enough DS30 resources available, an expansion module 
can be installed to provide the extra resources required. For information about setting DIP 
switches and installing an expansion module, refer to the BCM Installation and Maintenance 
guides supplied with the host system.
