Yogwiritsidwa ntchito moyenera mu transmission ya bi-directional (ikhoza kusungidwa) ndi equalization ya chizindikiro cha transmission ya trunk ya magulu ambiri kapena netiweki yogawa yomwe ikufunika kwambiri. Adopt PHILIPS, NEC imported power doubler modules. Audio pre-amplifier ndi amplifier ya microwave chubu yopukutira-kukoka yomwe ili ndi phokoso lotsika kuti itsimikizire kuchuluka kokwanira. Ili ndi input imodzi ndi zotulutsa ziwiri, ndipo kulumikizana kulikonse kumakhala ndi chitetezo cha over-current. Nthambi yotulutsa kapena distributiveness imatha kusinthidwa pambuyo pake. Double-equalizer imagwiritsidwa ntchito, kotero kusintha kusalala kwa transmission ya magulu ambiri ndikosavuta komanso kosavuta. Attenuator ndi equalizer ndi plug-in, kotero makasitomala amatha kusankha kalembedwe kokhazikika kapena kosinthika. Mphamvu yosinthira yodalirika kwambiri (kapena mphamvu yolunjika) komanso kapangidwe kolimba kosalowa madzi komanso kotsutsana ndi bingu kumatsimikizira ntchito yokhazikika.
