DTE mode—Molex LFH 200-pin connector and a DB-15-pin X.21 plug Cisco pays special attention to its network accessories which are the foundation stone of the whole network system. Cisco cables, adapters and other accessories will never let you down and you can always rely on the superior quality and outstanding reliability. Cisco has a wide range of network cables that will fit even the most extraordinary demands.

The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.
