Iisiguquli sephrothokholikubizwa ngokuthi isiguquli sephrothokholi, eyaziwa nangokuthi isiguquli esibonakalayo.Inika amandla abasingathi kunethiwekhi yokuxhumana abasebenzisa amaphrothokholi ahlukene wezinga eliphezulu ukuze basebenzisane ukuze baqedele izinhlelo zokusebenza ezisabalalisiwe ezihlukahlukene.Isebenza kungqimba yezokuthutha noma ngaphezulu.Isiguquli sephrothokholi esibonakalayo ngokuvamile singaqedwa nge-chip ye-ASIC, enezindleko eziphansi nosayizi omncane.Ingenza ukuguqulwa okufanayo phakathi kwe-Ethernet noma i-V.35 idatha interface yephrothokholi ye-IEEE802.3 kanye nesixhumi esibonakalayo esingu-2M sephrothokholi evamile ye-G.703.Ingase futhi iguqulwe phakathi kwe-serial port engu-232/485/422 kanye ne-E1, i-CAN interface ne-2M interface.

Incazelo yesiguquli sephrothokholi:

Ukuguqulwa kwephrothokholi kuwuhlobo lwemephu, okungukuthi, ukulandelana kokuthumela nokwamukela ulwazi (noma izehlakalo) zephrothokholi ethile kuhlelwa ngokulandelana kokuthumela nokwamukela ulwazi lenye iphrothokholi.Ulwazi oludinga ukufakwa kumephu luwulwazi olubalulekile, ngakho-ke ukuguqulwa kwephrothokholi kungathathwa njengokuhlela phakathi kolwazi olubalulekile lwezivumelwano ezimbili.Ulwazi okuthiwa lubalulekile kanye nolwazi olungabalulekile luhlobene, futhi kufanele lunqunywe ngokuvumelana nezidingo ezithile, futhi ulwazi olubalulekile oluhlukile luzokhethwa ukuze kwenziwe imephu, futhi kutholakale iziguquli ezahlukene.
