Cisco 72-0791-01 V.35 Male DTE Serial Cable DB60 WAN Router Serial

Cisco 72-0791-01 V.35 Male DTE Serial Cable DB60 WAN Router Serial

The Cisco 72-0791-01 is a synchronous serial cable that connects Cisco routers equipped with a DB60 WAN interface card to external CSU/DSU or network equipment using a V.35 Male connector on the DTE end. It carries the DTE (Data Terminal Equipment) designation, meaning it plugs into the router side of the connection and interfaces with a DCE device such as a channel service unit or modem. The cable is terminated with a 60-pin DB60 connector on the router end and a standard V.35 Male smart serial connector on the network equipment end.

Applications

V.35 serial cables like the Cisco 72-0791-01 are used to connect Cisco routers to WAN equipment — typically a CSU/DSU, DSL modem, or leased-line termination device operating over T1, fractional T1, or other synchronous serial WAN links. The V.35 interface was the dominant synchronous serial standard in enterprise and service-provider WAN networking through the 1990s and 2000s, and Cisco's Smart Serial DB60 connector became the standard on many of their router WAN interface cards during that period. These cables remain in active use today wherever legacy WAN interfaces, serial connections, or Cisco routers with DB60-based WAN cards are still deployed, including enterprise branch offices, government networks, and lab and test environments running Cisco equipment.
