problem, including the problem of routing cornmunications
and power cable to prevent damage.
Figure 14-10 shows the major items of equipment,
including a heavy tropo terminal, a patching
central, associated power units, and block-diagram
type cable interconnections. Sites B and F
have similar equipment configurations. In the
type company deployment shown, the site D
heavy tropo terminal would not include a PAT-
CENT that is organic to the heavy tropo company,
but would use the PATCENT facilities of
the collocated light tropo team. Because of the
limited number of personnel at a tropo team site,
arrangements should be made, if possible, to mess
with a larger unit in the area or to operate a consolidated
mess with other small units. However,
if the site is isolated, appropriate heavy tropo
company mess personnel will be assigned.

pairs is shown; in practice, a number of cables
and wire pairs are used. The circuits from supported
elements terminate in the PATCENT,
which has facilities to patch, reroute, and test all
communications circuits entering or leaving the
site. At the PATCENT, the cable and wire facili-
ties are interconnected with the tropo facilities
(and any collocated multichannel radio facilities
for which the PATCENT has responsibilities) in
accordance with the SYSCON SOP or in accord-
ance with SYSCON orders received through tech-
nical channels. Up to seven 26-pair cables may be
required between the PATCENT and the heavy
tropo terminal to carry the incoming and outgo-
ing voice and teletypewriter channels (a maxi-
mum of 60 voice channels or 59 voice channels
and 16 teletypewriter channels).
