which device is used to divide voice and data at subscriber end in dsl technology
Digital subscriber line At the exchange, a digital subscriber line access multiplexer (DSLAM) terminates the DSL circuits and aggregates them, where they are handed off to other networking transports.

The DSLAM terminates all connections and recovers the original digital information.
