Comtech CDD-564AEN, CDD-564ALEN & CDD-562ALEN

Overview

The CDD-564AEN, CDD-564ALEN and CDD-562ALEN are our next generation integrated IP demodulators with 3xDES data decryption providing industry leading performance in a 1 RU package at a competitive price. They are designed to receive up to four independent 70/140 MHz or L-Band channels (depending on model) and combine the receive data into a single 10/100Base-T Ethernet port for transmission onto the LAN. The demodulators are designed to operate with Comtech EF Data’s CDM-570/L-IPEN and CDM-570A/L-IPEN IP-enabled modems with 3xDES encryption.

Network Topologies

The CDD-562ALEN and CDD-564A/LEN are intended for use as hub receivers for Hub Spoke networks consisting of a shared outbound carrier with multiple return carriers from remote sites. The CDD-562ALEN and CDD-564A/LEN simplify hub deployment by reducing rack space and costs by providing two and four independent demodulators respectively in a 1RU chassis. At remote sites, the CDD-562ALEN or CDD-564A/LEN is used to enable single hop mesh connectivity between remote sites. Operating in mesh topology with direct connectivity between sites eliminates double-hop through the hub, thereby conserving bandwidth and reducing latency.

Data Decryption

The CDD-562ALEN and CDD-564A/LEN support 3xDES data decryption to prevent unauthorized access to data over the satellite link.

Quality Of Service (QoS)

The CDD-564A/LEN and CDD-562ALEN transparently pass the QoS prioritization established at the transmit end by the CDM-570/A/L￾IPEN Satellite Modem.
