CDM-600L Open Network Satellite Modem

The Comtech CDM-600L is an open network satellite modem, which is fully compliant with IESS-308, -309, -310, -314, and -315.  The 600L series VSAT modem provides variable data rate operation from 64 kbps through T2 and E2.

This modem is available in the following 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

Closed Network Configuration

In addition, the 600L series modem operates in closed network from 2.4 kbps to 20 Mbps. The modem includes 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. This satellite modem offers exceptional flexibility and performance in 1RU enclosures.

Feature Enhancements

Enhancing the modem’s performance is easy. Additional features are added quickly on site, using FAST access codes purchased from Comtech EF Data. To enable these features, simply enter the code at the front panel.

Turbo Product Coding

The modems offer all traditional FEC methods and incorporate an optional Turbo Product Codec (TPC). TPC is a FEC technique that delivers significant performance improvement when compared to Viterbi with concatenated Reed-Solomon. TPC simultaneously offers increased coding gain, lower decoding delay and significant bandwidth savings.

CDM-600L Outline Dimensions

Dual TPC codecs are offered as hardware options

The Low-Rate TPC codec operates up to 5 Mbps with limited code rates.  The High-Rate TPC codec operates up to 20 Mbps, and offers a full range of code rates (5/16 through 7/8, and 0.95) with all modulation types from BPSK to 16-QAM.

Special features of the modems are their ability to monitor and control the distant end of a satellite link using a Comtech EF Data proprietary overhead channel. This framed mode is called EDMAC. User data is framed and extra bits are added to pass control, status, and Automatic Uplink Power Control information. This process is completely transparent to the user. An RF transceiver (C-Band and Ku-Band) or Block Up Converter at the distant end of a satellite link may be controlled and monitored from the front panel of the modem using a low data rate FSK signal on the RX IF cable via the EDMAC channel.
