PCM modem

The OSD170 G.703 pulse-code modulation modem suits in-house links such as 2.048-Mbit/sec data-switch links. It operates as an analog link optimized for the transmission of balanced ternary signals with peak amplitudes of 2.37V, which will transmit G.703 signals from T1 (1.544 Mbits/sec) to E2 (8.448 Mbits/sec), without user adjustments. The modem operates at 850 or 1300 nm. Spanning distance is 30 km at 2.048 Mbits/sec when operating at 1300 nm.
