The STU-160 DSL Network terminating Unit is designed for leased-line data networks for terminal rates up to 128 kbps.

Features and Benefits

The unit is equipped with two independent terminal interfaces, which share the total available 128 kbps data transmission capacity.

It means you can connect two pieces of equipment to just one STU-160 modem. At the network side, the STU 160 modem is connected to an IUM

interface unit located in a MartisDXX node Eight STU-160 modems can connect to just one IUM interface unit (resulting in up to 16 64-kbps channel connections), so little investment

is needed to integrate and manage several modems and circuits in the MartisDXX system.
