RM8 Software defined Modem Modem & ALE Controller

RM8 Software Defined Modem & ALE Controller

The RM8 is a high data rate LF & HF data modem and ALE controller for standards-based BLOS naval and strategic data communications. The RM8 extends the functions found in the RM6-A to also include the STANAG 4538 / 3G ALE Automatic Radio Control System (ARCS) function. The RM8 units are suitable for NATO BRASS & BRE1TA (BRASS Enhancements 1 Technical Architecture) shore station deployments offering split-site 2G & 3G ALE.

When combined with a naval or strategic HF radio, the RM8 can provide 3G ALE scanning, channel selection, link set-up, Linking Protection and xDL packet data.

The RM8 is suitable for long distance point-to-point data links. The RM8 extends the capabilities of the RM6 to include STANAG 4538 3G ARCS. The RM8 is intended for installation into 19” rack systems.

The RM8 can be installed as both land and ship-borne 19-inch rack equipment. Up to two units can be installed in a single 1U slot.

The function of the RM8 is determined by the selection of one of the following software packs:

  • M1: LF & HF Modem (SSB, ISB, up to 19200 bps)
  • M2: HF Modem (SSB, up to 9600 bps)

The following ALE software options are available for use with M1 and M2:

  • 2G ALE Controller Software Option
  • 3G ALE Controller Software Option
