S.I.Tech 2896 Bit-Driver is designed to work with T1 systems. Model 2896 is a T1 to fiber optic
transmitter/ receiver full duplex product implementing T1 protocol, 2 CH rack mounted, power unit and built in
redundancy. (110VAC, 220VAC, or 48VDC)
This fiber optic Bit-Driver product eliminates many disadvantages of metallic T1 signals, especially EMI/RFI, ground
loops (electrical isolation with fiber), high attenuation (high signal loss), limiting distance between nodes of
system, and potential lightning damage outdoors between buildings.
S.I.Tech Model 2896 Bit-Driver is a rack mount product allowing easy change from T1 to fiber. Simply connect T1
cable to Model 2896 input/output port. Model 2896 comes with power supply and status indicators. 2896 provides
2-T1 channels. Unit works with 110VAC, 220VAC, and 48VDC input power, 50/60 Hz, 20W. Power can be switched ON or
OFF on eack channel, as well as primary. Unit can be used as 2 channels or redundant with automatic switch over.
