Navigation &

Communications Equipment (continued) work to provide voice and custom- ized data services between inland river towboats and their central of- fices. Full service was instituted in mid-1986.

The WATERCOM System, through a series of 54 shore stations, provides continuous coverage of ap- proximately 4,000 miles of inland waterways. It serves the Mississippi

River from south of New Orleans to

Minneapolis/St. Paul, the Illinois

River from the Mississippi to Chica- go, and the Ohio River from Cairo to Pittsburgh. On the Gulf Intra- coastal waterway, coverage extends from Apalachicola, Fla., to Browns- ville, Texas, with incidental cover- age on the Gulf of Mexico.

WATERCOM provides service comparable in quality to that of the

National Telephone Network, and in fact connects to NTN lines just like any other telephone network.

The WATERCOM system con- sists of three major components: vessel telephones, shore stations and the Operations and Control

Center in Jeffersonville. Vessel tele- phones consists of a radio transmit- ter and receiver, a microprocessor- based phone control unit, and the main telephone handset. An option- al extension phone may be added to provide credit card calls from facili- ties in the crew's quarters.

Each of the 54 shore stations serves compatible equipped vessels within its operating range, provid- ing continuous telephone service.

Each station is interconnected with the local area central control office, from which incoming and outgoing calls are routed to and from the ves- sel.

The Operations Control Center is the heart of the WATERCOM sys- tem. It provides the principal auto- matic switching and routing func- tions for all long-distance calls en- tering the system.

New Corrosion-Resistant

Monel Hose From Cajon —Literature Available

Monel flexible hose lined with

TFE, combining flexibility with the benefits of special alloy construc- tion, is now available from Cajon

Company, Macedonia, Ohio.

Monel is used for the hose over- braid as well as the end connections, providing chemical resistance, pres- sure capability and durability. The hose remains flexible at low temper- atures, and maintains its strength at high temperatures.

The smooth bore TFE lining as- sures low pressure drop. Tube

Adapter ends offer easy connection to tubing or NPT pipe systems.

Standard lengths are 12, 24 and 36 inches, with optional lengths available in one-inch increments from four inches to 20 feet. Service ratings are -65° to +450° F (-53° to +232° C), and 1,500 psi at 70° F (10,300 kPa at 21° C).

Application areas include chemi- cal service, sampling systems, hy- draulics and pneumatics.
