transceiver indhaha PDH(Plesiochronous Digital Heerarchy), oo ah nidaam taxane ah oo gudbinta dhijitaalka ah. transceivers indhaha ee PDH waa transceivers indhaha oo awood yar. transceivers indhaha PDH waxaa guud ahaan loo isticmaalaa labo-labo, sidoo kale loo yaqaan codsiyada dhibic-ilaa-point. Awoodda guud ahaan waa 4E1, 8E1, 16E1.

Shaqada transceiver indhaha ee PDH: Transceiver optical PDH waxay ku habboon tahay isku xirka beddelka awoodda yar, shabakadda loop isticmaalaha, isgaarsiinta mobilada (goobta saldhiga), shabakad gaar ah, shabakadda DDN, iwm.

Astaamaha transceiver indhaha PDH:
Waxay qabataa chip isku-dhafan oo baaxad weyn oo aad u weyn, kaas oo leh astaamaha isticmaalka tamarta hoose iyo isku halaynta sare. Bixi shaqada tijaabada loopback fog E1, fududahay in la ilaaliyo. Waxay bixisaa 4 E1 kanaal; waxa uu leeyahay hawl-qabad alaarmiga oo dhamaystiran, kaas oo soo bandhigi kara alaarmiga gudaha iyo kan fogba. Macluumaadka qaylo-dhaanta (oo ay ku jiraan alaarmiga cilladda korontadu) waxaa lagu wargelin karaa asaagga iyada oo loo marayo kanaalka maamulka shabakadda. Isticmaalka qalabka isku dhafan ee transceiver, waxqabad shaqo oo deggan oo la isku halayn karo. Naqshadaynta hal-board ee mashiinka oo dhan waa mid yar oo cabbir ah oo sahlan in la isticmaalo.

Afar faa'iido oo PDH ah transceiver indhaha:
1. Heer interface midaysan iyo heerka yara ee midaysan ayaa bixiya suurtogalnimada isku xidhka u dhexeeya aaladaha soo saarayaasha kala duwan.
2. Awoodda maamulka shabakada ayaa si weyn loo hagaajiyay.
3. Aragti ahaan, fikrad cusub oo shabakad is-bogsiineed ayaa la soo jeediyay. Marka calaamadda ugu weyn ee warbaahinta gudbinta la gooyo, waxay si toos ah u bilaabi doontaa isgaadhsiinta caadiga ah iyada oo loo marayo shabakadda is-bogsiinta. v
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.

transceiver indhaha PDH inta badan dhamaystirtaa E1 iyo Ethernet ganacsiga gelitaanka, oo uu garwaaqsado shaqada isgaarsiinta dhibic-ilaa-dhibcaha E1 signal iyo Ethernet signalka by dhufashada 1 signallada gudbinta. Qabo meel ka yar, qaabaynta dabacsan, ilaalinta tamarta laba geesoodka ah.
