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 local loop simulator 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 other local loop simulator products for a wide variety of
test configurations.
