efficiently in shelf 1, slot 1.

• No TIUs or SCCs in the node.
• The NCM cannot control some functions of a DIU 2140.
System Cabling

Connecting cables at customer premises must be within specified
distances between the Access System 2000 and external
equipment. These distances are critical for system operation.
Figure 3-1 shows the recommended maximum distances. Cables
available from Verilink are identified in Verilink’s Cable directory.
