The XMFC/MFE (Extended Multi-frequency Compelled/Multi-frequency 
sender-receiver) card is used to set up calls between two trunks. Connections 
may be between a PBX and a Central Office or between two PBXs. When 
connection has been established, the XMFC/MFE card sends and receives 
pairs of frequencies and then drops out of the call.

The XMFC/MFE card can operate in systems using either A-law or µ-law 
companding by changing the setting in software.

You can install this card in any IPE slot. 

The MFC feature allows the system to use the CCITT MFC R2 or L1 
signaling protocols.
