Wiring an R2MFC MBM

This section describes how to wire the cables that connect to the R2MFC MBM. The R2MFC
MBM is connected to the CO by either RJ48C or BNC connectors. The BNC connector is the
default interface. The default connector can be changed either by setting the country - selection
DIP switches or by creating a custom country code profile through the CLI. See
MFCR2 (external) link" on page 49
