3. Smart jack a type of network interface device that adds circuitry. This circuitry adds such
features as converting between framing formats on a digital circuit (for example,
a T1), supporting remote diagnostics, and regenerating a digital signal.
4. Demarc/demar- this is the point in a telephone network where the maintenance responsibility
cation passes from a telephone company to a subscriber (unless the subscriber pur-
point/demarc chased an inside wiring plan). This demarc is typically a box mounted to the
extension outside of a customer's building (for example, a residence). This box is called a
network interface device (NID).
5. tip and ring The red and green wires found in an RJ-11 wall jacks, which carry voice, ringing
voltage, and signaling information between an analog device (for example, a
phone or a modem) and an RJ-11 wall jack.
6. NT1 ISDN device that interconnects a 4-wire ISDN circuit with a 2-wire ISDN circuit.
