Tambo yefoni yeCat3 pamutengo wefekitori, mapeya gumi, makumi maviri, zana uye mazana matatu.
Tinofara kupindura mibvunzo chero ipi zvayo, ndapota titumirei mibvunzo yenyu nemirairo yenyu.

Mamwe mashoko
Nhanganyaya yeChigadzirwa
Tambo yefoni ine ma "high-pair" itambo yekutaurirana ine ma "multi-conductor" akawanda ine ma "twisted copper pairs", anowanzova pakati pema "25" ne2400, akaiswa mu "protective insulation" uye "outer jacket". Yakagadzirirwa kutumira izwi/data rakawanda, inotsigira masaini e-analog/digital asina kupindirana zvakanyanya nekuda kwe "twisted-pair geometry". Inowanzoshandiswa mu "backbone phone networks", zvivakwa zvemabhizinesi, uye ma "multi-house units", inoita kuti pave nekubatana kwakavimbika pamusoro penzvimbo refu. Zvinhu zvinosanganisira "polyethylene insulation", "PVC jacket", uye 24 AWG copper waya. Dhizaini yayo ye "modular" inoita kuti kuiswa uye kukura kuve nyore, nepo sarudzo dzekudzivirira dzichiwedzera kuramba kweEMI. Iyi zvivakwa ichiri yakakosha kune masisitimu ekare uye kubatanidzwa kweLAN/DSL kwemazuva ano.
Zvinhu zvirimo
Tambo dzefoni hombe dzine mawiri emhangura akasonwa (24 AWG) ari pakati pe25 neanopfuura 1200 ane polyethylene/PVC insulation. Dzakagadzirirwa network dzezwi nedata, dzinoderedza kutaurirana kuburikidza nekudzivirira uye kusonwa, dzichitsigira POTS, DSL, neVoIP pakufamba kwenguva refu.
Mashandisirwo
Tambo dzefoni hombe dzinosangana nezvinodiwa zvekutaurirana kwevanhu vakawanda: network dzemusana, zvivakwa zvinogara vanhu vakawanda, vanopa masevhisi eInternet, uye masisitimu ekampasi. Vanoparadzira izwi/data kubva kumahofisi makuru kusvika kune vashandisi vekupedzisira, vachitsigira masevhisi eanalog/digital akadai sePOTS, DSL, uye VoIP munzvimbo dzemukati nedzekunze.
