RM6-A High Data Rate Modem and 2G ALE Controller

Used for long distance, point-to-point, and point-to-multipoint data links, the RM6-A for low frequency (LF) and high frequency (HF) radios is a high data rate, standards-based strategic and maritime communications modem.

As an option, The RM6-A modem can include a 2nd Generation (2G) automatic link establishment (ALE) Controller that is activated by the user with a key selection for LF and HF modem software bundles and offers a compact solution for networking. The 2G ALE function can operate in combination with the RC66 or RC8 5066 Server and IP Controller directly through the remote control port.

Better Connectivity, Security with 2G ALE Networking 

To overcome variable HF propagation conditions, the RM6-A 2G ALE Controller provides better connectivity over a greater number of frequencies and allows linking to other HF stations in a network without operator intervention.

Performing all the basic protocol functions for individual calling, one-to-many calling, sounding and scanning up to 5 channels per second, the 2G ALE Controller provides advanced features with greater reliability than using a single frequency.

The 2G ALE Controller continually scans the pre-selected set of channels, and improves linking quality analysis by continuously listening to sounds and calls from other stations, when not otherwise committed.

MIL-STD-188-141B, App. B Linking protection provides additional security to your HF network.

2G ALE Front Panel Configurations and Controls

The RM6-A offers 2G ALE configurations and control via the front panel menu interface.

The RM6-A will operate with most legacy LF and HF voice radios and control protocols for additional radios can be added as needed.
