The E and M Trunk card brings the four analog trunks to the backplane
through a 160-pin connector shroud. External equipment connects to the
card at the back of the Media Gateway and Media Gateway Expansion
using a 25-pin connector. Telephone trunks connect to the E and M Trunk
card at the MDF using a wiring plan similar to that used for line cards.
