    product overview

    The Model 458-SM-2-16 Transparent Switching Module is a transparent, electrically neutral, multiplexing/demultiplexing device that allows up to sixteen incoming lines to share (be directed to) up to two independent local loop simulator output channels, or two incoming lines to share (be directed to) up to sixteen independent local loop simulator output channels. The user may select one or two of the inputs (or outputs) out of sixteen, with the unselected paths being terminated with 100 ohms.

    This powerful module is plugged into our Model 458-3SLB (3-Slot) or 458-CC-16/458-CM (16-Slot) rack-mounted chassis where settings are controlled by RS-232, Ethernet or IEEE-488(GPIB). The modular design of Telebyte's products allows the 458-SM-2-16 to be combined with our local loop simulator products for a wide variety of test configurations.
