The OSD170 PCM modem operates as an analog link optimized for the transmission of balanced ternary signals with peak amplitudes of 2.37V. It transmits any standard G.703 signal from T1 to E2 without user adjustments. Operation at either 850 or 1300 nm is available. The device comes in a self-contained case that takes up half a modem tray in a standard 19-inch rack.
