Summary:

 

 

 

This informal report has been issued to highlight a link of potential interest for tasking.
The physical gateways are ORDAN-USA, however USA is providing a logical gateway to the ROW.

The link is a fairly standard El employing Timeslot 31 to relay C7, which in turn provides the dialling for this
link. Compression is achieved by utilising DTX-36OB DCME equipment.

Traf?c summaries indicate that both terminals are relaying transit data.
