• two or four wire tie trunks
• 4-wire E and M Trunks:
- Type I or Type II signaling
- duplex (DX) signaling
• paging (PAG) trunks
Type I signaling uses two signaling wires plus ground. Type II and DX signaling uses two pairs
of signaling wires. Most electronic switching systems use Type II signaling.
The following table lists the signaling and trunk types supported by the NT8D15 E and M Trunk
card.

Physical description
The line interface and common multiplexing circuitry is mounted on a 31.75 cm by 25.40 cm
(12.5 in. by 10 in.) printed circuit board.
The E and M Trunk card connects to the backplane through a 160-pin connector shroud.
External equipment connects to the card at the back of the Media Gateway using a 25-pin
connector. Telephone lines from station equipment cross connect to the OPS analog line card
at the MDF using a wiring plan similar to that used for line cards. See
Communication Server
1000M and Meridian 1 Large System Installation and Configuration
(NN43021-310) for
termination and cross connect information.
Each card provides four circuits. Each circuit connects with the switching system and with the
external apparatus by an 80-pin connector at the rear of the pack. Each trunk circuit on the
card connects to trunk facilities by tip and ring leads which carry voice, ringing, tone signaling
and battery. Trunk option selection is determined by software control in LD 14.
