Abacus24-7 Cisco Router to Router Crossover DCE/DTE DB60 Cable: 1 ft

Description

DCE/DTE DB60 Crossover Cable - 1ft This cable is a 1ft V.35 DTE/DCE DB60-DB60 Crossover Back-to-Back Cable used to connect Cisco 1600/1700/2500/2600/3600 (WIC-1T, NM-4A/S, NM-8A/S on the 2600 and 3600) Series routers via their serial ports to simulate Frame-Relay and other WAN topologies. What is DTE/DCE? Data terminal equipment (DTE) is an end instrument that converts user information into signals for transmission or reconverts received signals into user information. A DTE device communicates with the data circuit-terminating equipment (DCE). The DTE/DCE classification was introduced by IBM. A DTE is the functional unit of a data station that serves as a data source or a data sink and provides for the data communication control function to be performed in accordance with link protocol. The data terminal equipment may be a single piece of equipment or an interconnected subsystem of multiple pieces of equipment that perform all the required functions necessary to permit users to communicate. A user interacts with the DTE (e.g. through a human-machine interface), or the DTE may be the user. Usually, the DTE device is the terminal (or a computer emulating a terminal), and the DCE is a modem.
