Transceiver indhaha PDH (Plesiochronous Digital Hierarchy, taxane dhijitaalka ah oo ka kooban) waa awood yar oo awood transceiver indhaha ah, guud ahaan codsiyada lammaane, oo sidoo kale loo yaqaan codsiyada bar-ilaa-point, iyo awoodda guud ahaan waa 4E1, 8E1, 16E1. Marka xigta,TECHNOLOGY JHAWaxaan si faahfaahsan u soo bandhigi doonaa faa'iidooyinka pdh transceivers indhaha, aan eegno!

1. Qiyaasta yara ee midaysan iyo halbeeg is-dhexgal midaysan ayaa bixiya suurtogalnimada isku xidhka aaladaha soo saarayaasha kala duwan.
2. Awoodaha maamulka shabakada ayaa si weyn kor loogu qaaday.
3. Soo bandhig fikrad cusub oo shabakad is-bogsiin ah. Foomka shabakada giraanta ee leh awoodda ilaalinta is-bogsiinta ee ka kooban qalabka SDH waxay si toos ah dib ugu bilaabi kartaa isgaadhsiinta caadiga ah iyada oo loo marayo shabakadda is-bogsiinta marka calaamadda ugu weyn ee dhexdhexaadiyaha la gooyo.
4. Tiknoolajiyada isku dhufashada Byte ayaa la qaatay si loo sameeyo calaamadaha laanta sare iyo hoose ee shabakada mid aad u fudud.

Sababtoo ah PDH waxay leedahay faa'iidooyinka cajiibka ah ee kor lagu soo sheegay, waxay noqon doontaa mid ka mid ah tignoolajiyada aasaasiga ah si loo xaqiijiyo macluumaadka superhighway. Laakin wadooyinka laanta iyo wadooyinka fargeetada ee ku xiran wadada weyn ee macluumaadka, PDH qalabka transceiver indhaha ayaa wali noqon doona mid faa'iido leh.

8E1 PDH transceiver indhaha waxay isticmaashaa wareeg balaadhan oo isku dhafan oo leh xuquuqaha hantida aqooneed ee madax banaan, waxayna khusaysaa kala qaybinta tignoolajiyada isku dhufashada si ay isugu daraan oo ay u codeeyaan calaamadaha E1 oo ay ugu gudbiyaan laba fiilooyinka indhaha ah. Alaabooyinka loo qaabeeyey iyadoo la isticmaalayo chip-kan waxay qaataan naqshad hal sabuur ah, oo leh is dhexgalka sare, cabbir yar, isticmaalka tamarta yar, shaqo la isku halayn karo, iyo rakibid fudud iyo isticmaal.
