T1 ndi T3 Mipata ya Network Communications

Mitsinje yapamwambayi ndi yoyenera kugwiritsira ntchito malonda

T1 ndi T3 ndi mitundu iwiri yofanana ya mawonekedwe a digito ya deta yomwe amagwiritsidwa ntchito poyendetsa mauthenga. Poyambitsidwa ndi AT & T m'ma 1960 kuti athe kuthandiza ma telefoni, mizere ya T1 ndi mizere ya T3 pambuyo pake inakhala njira yodziwika popereka chithandizo cha intaneti.

T-Carrier ndi E-Carrier

AT & T inakonza njira yake yothandizira T kuti athetse gulu limodzi la magulu onse pamodzi mu zigawo zazikulu. Mzere wa T2, mwachitsanzo, uli ndi mizere inayi ya T1 yokhala pamodzi.

Mofananamo, mzere wa T3 uli ndi mizere 28 T1. Njirayi inafotokoza magulu asanu-T1 kupyolera mu T5-monga momwe tawonedwera mu tebulo ili m'munsiyi.

Anthu ena amagwiritsa ntchito mawu akuti "DS1" kutanthauza T1, "DS2" kutanthauza T2, ndi zina zotero. Mitundu iwiri ya mawu otanthauzira mawu angagwiritsidwe ntchito mosiyana mosiyanasiyana. Mwachidziwitso, DSx imatanthawuza chizindikiro cha digito chikugwera mizere yofanana ya Thupi, yomwe ingakhale yamkuwa kapena yosanjikiza. DS0 "imatanthawuza chizindikiro pa imodzi yogwiritsira ntchito T-carrier, yomwe imathandizira mlingo waukulu wa data wa 64 Kbps . Palibe mzere T0 weniweni.

Ngakhale kuti mauthenga a T-carrier anatumizidwa ku North America, Europe inalandira njira yofanana yotchedwa E-carrier. Mchitidwe wothandizira E umagwirizanitsa lingaliro lomwelo la aggregation koma ndi majambulidwe otchedwa E0 kupyolera mu E5 ndi miyezo yosiyana ya iliyonse.

Anagwiritsidwa ntchito Line Internet Service

Ena opereka intaneti amapereka mizere yothandizira T-makampani kuti agwiritse ntchito monga kugwirizana odzipereka kwa maofesi ena osiyana ndi malo ndi intaneti. Amalonda amagwiritsa ntchito maofesi a intaneti ogwiritsidwa ntchito mwachisawawa kuti azipereka T1, T3 kapena magulu a T3 ochepa chifukwa chakuti amenewo ndiwo njira zabwino kwambiri.

Zambiri Zokhudza T1 Mipata ndi T3 Mipira

Omwe ali ndi malonda ang'onoang'ono, nyumba za nyumba, ndi mahoteli kamodzi adadalira mizere ya T1 monga njira yawo yoyamba yogwiritsira ntchito intaneti pamaso pa DSL inayamba kufalikira. T1 ndi T3 anachotsa mizere ndi njira zogulitsa zamtengo wapatali zomwe sizili zoyenera kwa ogwiritsira ntchito, makamaka tsopano kuti njira zina zambiri zothamanga zimapezeka kwa eni nyumba. Mzere wa T1 ulibe mphamvu zokwanira zothandizira zofunikira zogwiritsa ntchito intaneti masiku ano.

Kuwonjezera pa kugwiritsidwa ntchito pamsewu wamtunda wautali wamtunda, mizere ya T3 imagwiritsidwa ntchito popanga maziko a malonda a bizinesi ku likulu lawo. Ndalama za T3 zimakhala zochepa kuposa za mizere ya T1. Zomwe zimatchedwa "magawo tagawuni" amalola olembetsa kulipira nambala yaing'ono kuposa mzere wathunthu wa T3, kuchepetsa ndalama zothetsera ngongole.
