8E1 + 4FE PDH MultiplexerJHA-CPE8F4

Txheej txheem cej luam

Cov cuab yeej no muab 1-8 * E1 interface, 1-4 * 10M / 100M Ethernet interface (Wire Speed ​​100M) thiab 2 expansion interface. 4 * Ethernet interface yog hloov pauv, tuaj yeem txhawb VLAN. 2 nthuav dav interface tuaj yeem siv los ua kev sib kis ntawm RS232 / RS485 / RS422 asynchronous cov ntaub ntawv. Nws hloov tau yooj yim heev. Nws muaj lub tswb ua haujlwm. Kev ua haujlwm yog txhim khu kev qha, ruaj khov, thiab kev siv hluav taws xob tsawg, kev sib koom ua ke siab, me me.

Khoom duab

Nta

• Raws li tus kheej-copyright IC

• Siv tus qauv 2 xov tooj xov tooj (tsis yog xov tooj tuav) teeb tsa raws li kev txiav txim hluav taws xob-xaim xov tooj (yeem)
• Muab 2 expansion interface tuaj yeem siv tau raws li kev sib kis ntawm RS232 / RS485 / RS422 asynchronous cov ntaub ntawv
• Thaum kho qhov muag poob teeb liab, nws tuaj yeem ntes cov khoom siv tej thaj chaw deb yog hluav taws xob lossis fiber ntau raug txiav, thiab qhia lub tswb los ntawm LED
• Cov cuab yeej hauv zos tuaj yeem saib cov cuab yeej ua haujlwm nyob deb
• Muab cov lus txib rau tej thaj chaw deb interface Loop Back, yooj yim kho kab
• Qhov kis tau tus mob mus txog 2-120Km yam tsis muaj kev cuam tshuam
• AC 220V, DC-48V, DC24V tuaj yeem xaiv tau
• DC-48V / DC24V fais fab mov polarity nrhiav pom muaj nuj nqi, Polarity-dawb
