Isango Lokuhlela Ikhasi le-SIP JWDT-PA3
I-JWDT-PA3 incane futhi inesitayela, efanelekela isikhala esilinganiselwe ezimweni eziningi zohlelo lokusebenza. Ngokusebenzisa i-wide-band audio decoding G.722 kanye ne-opus, i-JWDT-PA3 ilethela abasebenzisi ulwazi olucacile lwe-telecom auditory. Ine-interface ecebile futhi ingathuthukiswa ibe amadivayisi okusakaza, ama-amplifier kanye nama-intercom ukuze kuhlangatshezwane nezidingo ezahlukene. Ngokusebenzisa i-interface ye-USB, i-Max to 32G noma i-TF card interface, i-JWDT-PA3 ingasetshenziswa ukwenza ukusakaza kwendawo okungaxhunyiwe ku-inthanethi kwe-MP3 kanye nokusakaza ku-inthanethi. Abasebenzisi bangabuka isithombe sevidiyo ye-HD sekhamera efonini ye-IP ngale SIP Paging Gateway, ukuze baqaphe isimo esizungezile ngesikhathi sangempela.
1. Okuhle kakhulu, kungafakwa kweminye imishini yokufaka ngaphakathi
2. Ukukhipha kwe-amplifier yamandla esiteshi esisodwa esingu-10W ~ 30W, ngokuya nge-voltage yokufaka ekusethweni kwamandla okukhipha.
3. Ulayini womsindo ongaphakathi kwembobo, isikhombikubona somsindo esijwayelekile esingu-3.5mm, ipulaki bese udlala.
4. Imbobo yokuphuma komugqa womsindo, isikhulumi esisebenzayo sangaphandle esinganwebeka.
5. Sekela imbobo ye-USB2.0 kanye nesikhala sekhadi le-TF sokugcina idatha noma ukusakaza umsindo ungaxhunyiwe ku-inthanethi.
6. I-Adaptive 10/100 Mbps network port ehlanganisiwe ye-PoE.
I-JWDT-PA3 iyithuluzi lesistimu ye-SIP Public Announcement lokusetshenziswa kwemboni. I-media stream transmission ifaka amaphrothokholi ajwayelekile e-IP/RTP/RTSP. Inemisebenzi ehlukahlukene kanye nezixhumi, njenge-Intercom, ukusakaza kanye nokuqopha, ukuze ivumelane nezimo ezahlukene zesicelo. Abasebenzisi bangazilungiselela kalula idivayisi ye-paging.
