E(Ear or Earth) - Signal wire from trunking(CO) side to signaling side.
M(Mouth or Magnet) - Signal wire from signaling side to trunking(CO) side.
SG(Signal Ground) - Used on E & M Types II, III, IV
SB(Signal Battery) - Used on E & M Types II, III, IV
TIP/RING - T/R leads carry audio between the signaling unit and the
trunking circuit. On a 2-wire audio operation circuit, this pair carries the
full-duplex audio path.
TIP1/RING1 - Used on 4-wire audio operation circuits only. The 4-wire
implementation provides separate paths for receiving and sending audio
signals.
The following Figure 30.8 shows a whole Jumper information for E & M Board.
