8E1+LCD Chiwonetsero +SNMP JHA-C2P-E8bF4R2

PDH Fiber Multiplexer

Mwachidule

Chipangizochi chili ndi chowongolera, chimapereka chitetezo cha 1 + 1 fiber back-up, kuloza kufalikira kwa kuwala, chiwonetsero cha LCD, pamaziko amakampani athu opanga ma PDH optical transmission, gwiritsani ntchito VLSI yapadera ndi SNMP NMS.

Chipangizochi chimapereka mawonekedwe a 1-8 * E1, 1-4 * 10 / 100M Ethernet mawonekedwe (Wire speed 100M) ndi 2 mawonekedwe owonjezera. Mawonekedwe a 4Channel Efaneti ndi mawonekedwe osinthira, amatha kuthandizira VLAN. 2 mawonekedwe owonjezera angagwiritsidwe ntchito ngati njira yotumizira ya RS232/RS485/RS422 data asynchronous. Imasinthasintha kwambiri. Ili ndi ntchito ya alamu. Ntchitoyi ndi yodalirika, yokhazikika, komanso yotsika mphamvu yogwiritsira ntchito mphamvu, kuphatikiza kwakukulu, kukula kochepa

Chithunzi cha malonda

Mawonekedwe

• Amapereka 8 E1 kufala mandala;
• Ndi char 16 * 2 LCD chiwonetsero ndi SNMP wothandizira mkati
• Perekani mawonekedwe a Console (RS232)
• Perekani mawonekedwe awiri a fiber 1 + 1 kuteteza (APS) ntchito, ndi ALS (Automatic Laser Shutdown/Reduction) ntchito
• Kuthandizira kukula kwa phukusi la Ethernet 1916 byte ndi 4 Ethernet port zitha kukhazikitsidwa padera, ndipo bandwidth ya ethernet ikhoza kukhala yoyambira pa angapo a 32K.
• Amagwiritsa ntchito matelefoni amtundu 2 (zotengera zosagwirizana ndi foni) zokhazikitsidwa ngati mainjiniya oyitanitsa-waya hotline(posankha)
• Perekani maulalo awiri a ulusi, imodzi ngati mbuye, inayo ngati kapolo, kutsimikizira kutumizirana mauthenga mosadodometsedwa
• Mlingo wa doko kuwala ndi 155Mbps, kufala osiyanasiyana akhoza kufika 25KM, 40KM, 60KM, 80KM kapena 120KM;
• E1 mawonekedwe kachidindo ndi HDB3, E1 kugwedera khalidwe zimagwirizana ndi ITU-T G.703, G.823 ndi G.742;
• Efaneti doko amathandiza zonse / theka duplex, 10/100M auto-Nego;
• Doko la Efaneti limathandizira ntchito ya VLAN ndipo ili ndi mawonekedwe a 4 pakusankha kwa ogwiritsa ntchito;
• Ili ndi ntchito yathunthu ya alamu ndipo imatha kuyang'anira mawonekedwe a chipangizo chakutali;
• Imathandizira ma Fiber Loop-back awiri, ndi Four E1 loop-back mode, ndikuwongolera chipangizo mosavuta;
• Alamu yayikulu yosinthika ndi ogwiritsa ntchito ndi alamu yaying'ono, yowonetsedwa mu LCD ndi alamu yamawu pa speaker;
• AC 220V, DC-48V, DC+24V ikhoza kukhala yosankha
• DC-48V/DC+24V mphamvu yozindikira polarity ntchito, Polarity-Free
