TYPICAL MERLIN II SYSTEM WIRING

Figure 2-2illustrates typical MERLIN II system wiring. Central office lines enter the site through a 25-pair cable. The network interface in this example is a 66-type block configured as an RJ21-X-type connector. From the network interface, a DIW cable takes the 25 lines to a jack field for outside lines. The jack field interfaces the outside line wiring with D2R cords that plug into the line jacks on the control unit modules. At this point, outside lines are connected to the control unit.

The station side of the control unit goes to a jack field for voice terminals through D8W cords. The other side of the jack field goes to the 102A connecting blocks through 4- pair DIW cable. The voice terminals plug directly into the connecting blocks through four-pair modular cords.
