The DLS 400HE is a two wire ETSI HDSL / ETSI SDSL / ITU-T G.shdsl cable
simulator which can be equipped with up to two xDSL DLS 5A01 Impairment
Generator Modules. The DLS400HE is offered in three pre configured versions
designed to provide an effective partial or complete solution for the simulation
of ETSI HDSL & SDSL.
As with other Spirent Communications DLS Systems wireline simulators, wireline length, line configuration, and various noise impairments are set using the IEEE 488 or the RS-232 interface. The command language used is based on the Standard Commands for Programmable Interfaces (SCPI) standard (a subset of IEEE 488.2 (GPIB)).
