The Customs Over The Horizon Enforcement Network (COTHEN) uses a Rockwell/Collins ALE (Automatic Link Establishment) protocol to connect users to each other over the HF spectrum. If you listen to frequencies in use on the COTHEN network, you will hear the ALE sounding calls which units periodically and automatically initiate to determine the best frequency to use for calls to other units.

The COTHEN network now uses the MIL-STD 188-141A protocol. It formally used the FED-STD-1045A ALE protocol, developed by Rockwell Collins. The FED-STD protocol is Rockwell Collins proprietary and goes by the tradename Selscan. Selscan is no longer actively used by the COTHEN network.
Note: 8912 is also used by the HFDL (HF Datalink - also referred to as HF ACARS) net, particularly out of Riverhead NY, and is the source of other digital data heard here
