DTE-to-DCE Wiring

DTE-to-DCE Wiring

A DTE-to-DCE connection should not have rolls. The same effect can be achieved with having two rolls and the connector. Cisco routers come with a kit for console and auxiliary port cabling. The kit includes the following:

The RJ-45-to-DB-9 female DTE adapter is typically used to connect a PC being used as a console terminal. The RJ-45-to-DB-25 female DTE adapter is used to connect a terminal to the console or auxiliary port. The RJ-45-to-DB-25 male DCE adapter is used to connect the auxiliary port to a modem. Table 3-2 describes the port types for console and auxiliary ports on Cisco routers.
