Chapter 3 Preparing to install the R2MFC MBM 29
R2MFC MBM setup requirements
This section provides the following information about the setup requirements for the R2MFC MBM:
•“Config DIP switches”
•“MBM DIP switches”
•“Environment checklist”
•“Software requirements” on page 30
•“Electrical requirements” on page 30
Config DIP switches
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 “Configuring the MFCR2 (external) link” on page 49 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 Appendix A, “Configuring DIP switch settings and definitions,” on page 91 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 “Turning on second dial tone” on page 58 for a procedure on how to set the DIP switches, and configure the BCM for second dial tone to work properly.
MBM DIP switches
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.
