I'm not certain I understand your question, however: If you have one four wire E&M trunk interface then you can only handle one call over it at a time. E&M is a handshaking protocol, not a multiplexing protocol (such as the protocols used by T1 circuits, which give 24 channels on one pair).
Hope that helps.
