The CDM-600 are open network satellite modems, which are fully compliant with IESS-308, -309, -310, -314, and –315 from 64 kbps through T2 and E2.
They are available in the following three data rate ranges:
• Low-Rate variable: 2.4 kbps to 5.0 Mbps
• Mid-Rate variable: 2.4 kbps to 10.0 Mbps
• High-Rate variable: 2.4 kbps to 20.0 Mbps In addition, both modems operate in closed network from 2.4 kbps to 20 Mbps. The modems include T1, E1, T2, and E2 G.703 interfaces, in addition to EIA-422, V.35, EIA-232, and serial LVDS. HSSI is provided by adding the CIC-20 interface converter. The architecture is firmware and FPGA-based, and the internal Flash memory allows easy updating via the serial port. The modem offers exceptional flexibility and performance in a 1RU enclosure.
