The 39th Signal Battalion commands all units north of Giessen, including those units in Belgium, the Netherlands, and the United Kingdom plus Satellite Station AN/FSC-78 at Harrogate, England. In the 2d Signal Brigade's southern sector, the 102d Signal Battalion commands all units east of Worms and the 73rd Signal Battalion commands all units west of Worms plus Satellite Stations AN/MSC-46 and AN/FSC-78 at Landstuhl.

4. OPERATIONS. The backbone of the Defense Communications System (DCS) in Europe is called the European Wideband Communications System (EWCS). The 2d Signal Brigade has the responsibility for the central and northern Germany and Benelux portions of the system; both American and German equipment is used. Within this system we operate wideband stations, technical control facilities and minor patch and test facilities that control approximatelv 335 trunks and 2500 circuits of standard and special service communications. Our stations are permanently installed fixed plants.

To coordinate, control and supervise the transmission media and equipment of the EWCS, the 2d Signal Brigade has four major technical control facilities located at Pirmasens, Donnersberg. Frankfurt, and Worms.

In support of our DCS mission, we operate 1 of the 16 overseas automatic message switching centers in the DCS Automatic Digital Network (AUTODIN) located at Pirmasens, FRG. This network is similar to networks designed to deliver record communications or telegrams. However, AUTODIN, the Department of Defense record communications network, has been designed to meet special security, speed and reliability requirements. Security is provided by encoding all messages which leave an automatic message switching center. Speed is attained by computer processing each message in accordance with its precedence. Reliability is achieved by locating switching centers strategically throughout the world, by providing necessary back-up equipment, and by connecting the switching centers with many diversely routed, highspeed circuits. Our switch at Pirmasens can handle an input of up to 200 separate subscribers, and processes an average of 65 to 70,000 messages per day.

In the system with the automatic message switching center, we operate 32 telecommunications centers throughout our area of operation. These telecommunications centers provide record communications service for all units and activities in their immediate vicinity.

The 2d Signal Brigade operates three satellite terminals: an AN/FSC-78 at Harrogate, England; an AN/MSC-46 (which is scheduled to be replaced by the GSC-39 in the near future); and an AN/FSC-78 at Landstuhl. All terminals provide the most advanced technological and reliable access for selected subscribers into the worldwide Defense Communications System.

At Pirmasens, we have a long haul, high frequency radio facility operated by the 73d Signal Battalion. This facility has a dual role: on one hand it operates a radio trunk to Incirlik, Turkey; on the other hand it serves as the only Army entry point into the European Defense Communications System for high frequency, contingency operations. An average of 15 high frequency, contingency missions are activated through this station annually.

An Automatic Voice Network (AUTOVON) switching center is operated at Donnersberg. This switch is a part of the AUTOVON system, the principal long haul telephone network of the DCS. The purpose of the AUTOVON network is to provide a worldwide, automatic voice communications system to fulfill the nonsecure voice requirements of the Department of Defense. The AUTOVON System began in 1964 with 9 switches; it now has 16 operational switching centers overseas. Our Donnersberg switch has 377 connected subscribers.

Both narrow band subscriber terminals and secure voice cordless switchboards are parts of the Defense Communications System Automatic Secure Voice Communications (AUTOSEVOCOM) network. This network has approximately 1400 subscribers throughout the world. It is made up of manual and automatic switches and can provide from 3 to 250 subscribers with secure voice service.

In support of the AUTOSEVOCOM network, the 2d Signal Brigade operates 15 narrow band subscriber terminals and two secure voice cordless switchboards. The former is basically an AUTOVON circuit with secure voice service, and the latter is a manual switchboard that can provide such service for up to 15 local subscribers.

The 2d Signal Brigade provides command and control communications support to the US European Command (USEUCOM) and the 59th Ordnance Brigade at 33 locations. This support is provided through systems commonly referred to as the Europe Command Control Console System (ECCCS) and the Cemetery Net. Both systems are utilized to pass emergency action messages from HQ USEUCOM to the various 59th Ordnance Brigade detachments in our area of operations. The Cemetery Net is an HF network utilizing the AN/FRC-93 and KWT-6 Radio sets at fixed locations. To supplement the fixed locations and support the Ordnance and Artillery detachments when they are deployed to the field, the 2d Signal Brigade operates and maintains 52 mobile contingency units, utilizing the AN/MRC-117 (37), AN/TRC-133A (4), and AN/GRC-122A (11) radio sets.

(1) Cemetery Net radio equipment
AN/FRC-93 -- a high frequency (HF) commercial single-sideband radio set adapted for military use (AN/FRC-93).
KWT-6 -- KWT-6
AN/MRC-117 -- AN/MRC-117
AN/TRC-133A -- this radio set, composed of five single-sideband (SSB) radios, was the prime means of Pershing communications (WIKIPEDIA entry).
AN/GRC-122A -- a shelter-housed transportable radio teletypewriter set that uses the AN/GRC-106 as its major basic component. The AN/GRC-122 is authorized for air defense artillery battalions primarily to provide teletypewriter communication with higher headquarters.
