Dial pulses or DTMF tones are then presented from the CO. When the
called party answers, the universal trunk card reverses battery and ground
on the tip and ring leads to the CO. The trunk is arranged for first party
release. The CO releases the trunk by removing the low-resistance loop, at
which time normal battery and ground are restored at the near-end. This
also applies to incoming tie trunk calls from a far-end PBX.
An incoming call from the CO places a low-resistance loop across the tip
and ring leads. See
