Comtech EF Data CDM-700 Ultra High Speed Satellite Modem

CDM-700 Ultra High Speed Satellite Modem

Comtech CDM-700 is an ultra high-speed satellite modem that's specifically designed and intended for broadband operation with a range of multi-port data interfaces. The modem operates in broadcast, circuit restoration, point-to-point, disaster recovery and point-to-multipoint applications with exceptional power and bandwidth efficiency.  The highly versatile 700 series modem offers users an exceptional platform for delivering highly reliable communications services.

TURBO PRODUCT CODING (TPC)

The CDM-700 offers Turbo Product Coding. TPC simultaneously offers increased coding gain, lower decoding delay and significant bandwidth savings compared to Viterbi and Reed-Solomon (RS). The TPC rates are:

• Rate 3/4 for QPSK, 8-PSK, 16-QAM, 64-QAM
• Rate 7/8 for QPSK, 8-PSK, 16-QAM, 64-QAM

REMOTE CONTROL

The operator may configure and monitor the modem from the front panel, or through the remote M&C port. Control and status is provided through the RS-232, RS-485 (2/4 wire) port or 10/100 BaseT Ethernet port.

SOFTWARE - FLASH UPGRADING

The internal software is both powerful and flexible, permitting storage and retrieval of up to 10 different modem configurations. The modem uses 'flash memory' technology internally, and new firmware can be uploaded to the unit from an external PC. This simplifies software upgrading, and updates can now be sent via the Internet or e-mail. The upgrade can be performed without opening the unit by simply connecting the modem to the Ethernet port of a computer.

FULLY ACCESSIBLE SYSTEM TOPOLOGY (FAST)

The CDM-700 is extremely flexible and powerful, and incorporates a large number of optional features. Some customers may not require all of these features, and therefore, in order to permit a lower initial cost, the modem may be purchased with only the desired features enabled. If, at a later date, a customer wishes to upgrade the functionality of a modem, CEFD provides a system known as FAST which permits the purchase and installation of options through the use of special authorization codes, entered through the front panel, or remotely.
