Overview

Figure 1-1. CDM-750 Advanced High-Speed Trunking Modem

The CDM‐750 Advanced High‐Speed Trunking Modem (Figure 1‐1) is intended for network
operators, enterprise users, and service providers requiring maximum throughput while using
minimal satellite resources in point‐to‐point links. The CDM‐750 combines DVB‐S2 modulation
and coding with Comtech's DoubleTalk
Adaptive Coding and Modulation (ACM) technologies to optimize high speed satellite data links.
The CDM‐750 architecture allows efficient networking and transport over satellite links while
supporting a wide range of applications and network topologies.

1.2 CDM-750 Functional Description
The CDM‐750 Advanced High‐Speed Trunking Modem:
•
Features a high performance processor and a real‐time operating system (RTOS)
combined with multiple Field Programmable Gate Arrays (FPGAs). All non‐volatile
memory is provided by both onboard and Compact Flash devices.
•
Runs on an embedded operating system and does not have moving parts for media
storage. This design provides carrier class reliability and high speed, purpose‐driven
processing.
