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 “Configuring the MFCR2 (external) link” on page 49 for information on how to change the active interface.

If the 75 Ω BNC connector pair is used, two coax cables are required for transmit and receive.

If the 120 Ω RJ-48 connector is used, the cable pinout must be set up as follows:
