What doc?

E&M refers to the channelized signaling provide on a T1 using
the A and B bits, i.e. it is a digital parameter.

FXO is an analog telephone port that must connect to a PBX
or CO switch, i.e foreign exchange office.

FXS is an analog port that must be connected to a telephone
or other instrument capable of taking calls, i.e. foreign
exchange station.

Normally an FXO port would never connect to another FXO port.
