Cables and Connectors

This chapter describes the I/O interfaces, the data cables, and power cordsets required in using the LS2020 enterprise ATM switch. These facilities are described in the following order:

• Low-speed connectors and data cables for X.21, RS-449, and V.35 serial interfaces.
  
  
• Circuit emulation access card (CEMAC) connectors and data cables for 75-ohm and 120-ohm interfaces.
  
  
• Medium-speed connectors and data cables for the 2-port access card, the 4-port T3/E3 access card, and the 8-port T3/E3 access card.
  
  
• OC-3c connectors and data cables
  
  
• FDDI connectors and data cables
  
  
• Ethernet connectors and data cables
  
  
• Fiber Ethernet access card (FEAC) connectors and data cables
  
  
• Console and modem connectors and data cables
  
  
• Country kits and power cordsets
  
  

Signal diagrams are provided for each I/O connector and data cable.

For most cables, two part numbers are provided in an associated table in the body of the chapter: the manufacturing number (which appears on the cable itself); and the order number (which is used in ordering the cable from Cisco Systems). Cables without associated order numbers are not available from Cisco Systems; such cables are widely available from other vendors as standard items.
