FAMILY OF SERVICES

(FOS)

FOS is accessible via dedicated telecommunications access lines in the Washington, D.C., area. All FOS data services are driven by the NWS Telecommunication Gateway computer systems located at NWS headquarters in Silver Spring, MD.

Users may obtain any of the individual services from NWS for a one-time connection charge and an annual user fee. Several private companies subscriber to the FOS and then resell the data as received and/or provide value-added information services for their customers.

Additional Data and Products

Some WMO Member countries have defined a set of products which must not be re-exported back to the country of origin. Lists of these products, which are expected to be received at RTH Washington (the NWS Gateway), are provided for your information [ reference Additional Data and Products, WMO Resolution 40 (Cg-XI) ]. These lists also denote which data and products are currently carried in the FOS.

The established requirements for the FOS are listed by WMO abbreviated heading by the various FOS data streams and are available to download from this server.

If there are any special adapter cables, they should also be provided by the customer. Installation should also be provided by the customer and should include any configuration that is specific to the equipment provided.

The Server Access Service (SAS) provides access to the NWSTG networks and resources that reside there, in particular the File Server.

All routing should be performed by means of Static Routes.

Any points not covered will be worked out between the NWSTG and the customer.
