Intandokazi yesikhathi se-inthanethi - isipikha senethiwekhi se-POE

Ulwazi lwenethiwekhi lwanamuhla luyashintsha futhi luthuthuka ngesivinini esikhulu, esisinikeza lula olukhulu. Isidingo sabantu sokusakaza esidlangalaleni naso sihlala sikhula. Singakwazi yini ukuxhuma izipikha ezikhona ze-analog ezingasebenzi kunethiwekhi futhi sibe yintandokazi yesikhathi senethiwekhi ukuze senze isipikha senethiwekhi se-SIP/IP, ukuze singabe sisadinga amadivayisi ayinkimbinkimbi amaningi ukuthi asebenze ndawonye? Ukusakaza noma ukudlala umculo wangemuva.

Ngokombuso wale mfuneko, ngifune izinkampani eziningana, futhi ngengozi, embukisweni, ngabona inkampani ebizwa nge-OBT eyayinalo mkhiqizo ebengiwufuna isikhathi eside. Bangikhombise izipikha ezahlukene. Umsebenzi, ukufinyelela i-LAN nge-RJ45, i-bandwidth ifika ku-100MBPS, ukusebenza kulula kakhulu, akukho ukulungiswa ngesandla, ukuxhumana kwenethiwekhi kungaqedela ngokuzenzakalelayo ukuxhumana neseva, ukwesekwa kohlelo lwesikhathi oluvela kusinye, imemori yendawo ngezindlela ezimbili, kungaqedela ngokuzenzakalelayo uhlelo lwesikhathi nesinye Ukuvumelanisa, lapho uhlelo lweseva lushintsha, umsebenzi wokuvumelanisa ngokuzenzakalelayo ngemuva kokuxhuma kunethiwekhi (ingabe ihlakaniphile kakhulu?) Ukwesekwa kokwamukela ukusakazwa okukude okukude, ukusakazwa kweqembu nokusakazwa kwesifunda (akudingi ukuya yonke indawo ukulungisa), ukwesekwa kwe-cross-VLAN noma i-Layer 3 routing isetshenziswa.

Ngaphandle kwesishintshi samandla sangaphandle esingu-12V, lesi sipikha senethiwekhi singakwazi futhi ukunikezwa amandla yi-POE (PowerOverEthernet) (i-IEEE802.3af standard), ngakho-ke asidingi ukudonsa enye intambo yamandla, futhi kunciphisa ingozi yokuphepha, futhi sihle kakhulu. Ngale ndlela, kudingeka kuphela ukuxhunywa kwentambo yenethiwekhi eyodwa ukuze kufakwe, futhi ukwakhiwa kulula kakhulu, okunciphisa kakhulu izindleko zokufakwa. I-protocol yokudlulisa iyinkambiso ye-TCP/IP protocol. Ngaphezu kwalokho, lesi sipikha singakwazi futhi ukusekela i-SIP protocol.

Ukudluliswa kwedijithali okugcwele, i-chip eyakhelwe ngaphakathi yebanga lezimboni esheshayo, ibhodi lomama lamandla angu-2*15W kanye nemodyuli ye-POE, kusetshenziswa ubuchwepheshe bekhompyutha obufakwe ngaphakathi kanye nobuchwepheshe bokucubungula okulalelwayo be-DSP, iyunithi yesipikha esigcwele ibhande, ukuzwela okuphezulu, namandla amaningi, ikhwalithi yomsindo wezinga le-CD eliqinisekile.

Isithombe sokubukeka komkhiqizo:

Izipikha zepulasitiki ezisezingeni eliphezulu, ezinhle futhi ezinhle, ubuchwepheshe, ezigcwele isimo esiphakeme.

Umngane nje udinga lo mkhiqizo we-webcast. Ngiphakamise lo mkhiqizo wokusakaza ohlakaniphile kubangani bami ngaphandle kokungabaza, kodwa indawo yokusebenzisa ifaneleka kakhulu izipikha ezikhuluma isiNgisi. Bathola le nkampani ukuyibuza ukuthi ingakwazi yini ukwenziwa ngokwezifiso ibe mhlophe. Le nkampani ayizange ingabaze ukuvuma isicelo sethu, ngempela ifuna imicabango yekhasimende, ubunzima bekhasimende, isinikeza izinsizakalo ezenziwe ngokwezifiso, ingumphakeli wokubambisana wesikhathi eside omuhle kakhulu.
