The T1 CSU/DSU WAN interface is available for the Contivity Extranet Switch 1530. The T1 CSU/DSU WAN crossover cable crosses the blue pair with the orange pair. This is different from the commonly available crossover cable, which crosses the green pair with the orange pair. No cables are supplied with the T1 CSU/DSU. Table
