Diablo Cable 1ft Smart Serial Male DTE to LFH60 Male DCE Crossover Cable for Cisco CAB-SS-2660X-1
The 26-PIN Male DTE Smart Serial interface is used to connect to Cisco WAN Interface Cards including WIC-2T, WIC-2A/S, HWIC-2T, and HWIC-2AS, while the LFH60 DCE male serial connector will interface to WIC-1T, HWIC-1T, NM-4T, and NM-4A/S cards and modules. An example would be a Cisco 2811 with a WIC-2T needing a crossover connection to a Cisco 1750 with WIC-1T.
