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