Telebyte's 458 line modules simulate several cable types and offer the bandwidth requirements for today's xDSL technologies such as varieties of G.SHDSL, ADSL, ADSL2+ and VDSL2. Line lengths and configuration settings appear on an LCD display on the front of the unit and can be set via a keypad. We also offer other modules that work with our 458-CC-16/458-CM including the 458-SM-2-16 Transparent Switching Module.
