If correctly connected, the copper-colored wire (compared to the silver-colored wire) or the wire with the white stripe (compared to the wire with no stripe) should be your positive wire. If your amp or speaker has color-coded connections, the positive should connect to the red connection. If you are looking at the raw frame speaker inside the box, the positive should connect to the speaker terminal with the little paint mark or the + symbol next to it.
JCIDS is a joint-concepts-centric capabilities identification process that allows joint forces to meet future military challenges. The JCIDS process assesses existing and proposed capabilities in light of their contribution to future joint concepts.
Several types of NIDs provide more than just a terminal for the connection of wiring. Such NIDs are colloquially called smartjacks or Intelligent Network Interface Devices (INIDs) as an indication of their built-in intelligence, as opposed to a simple NID, which is just a wiring device. Smartjacks are typically used for more complicated types of telecommunications service, such as T1 lines.
