Gigabit Ethernet pa STM-4 SDH Converter

Kufotokozera

Chidule
Gigabit Ethernet/STM-4 Converter (BD-EOS-GE/STM-4 posachedwa) imatenga ukadaulo wa SDH ngati maziko ake kuti apereke mwayi, kugwirizanitsa, kutumiza ndi kuyang'anira ntchito za TDM ndi mautumiki a Broadband IP, ndipo ndi chipangizo kuti mutembenuzidwe momveka bwino pamagwiritsidwe ntchito a ma telecommunications wamba ndi ntchito za data za Broadband.
Gigabit Ethernet kupita ku STM-4 converter ndi Ethernet pa SDH mawonekedwe osinthira zida zoperekedwa ndi mawonekedwe awiri a STM-4 optical, ma Ethernet awiri amagetsi ndi mawonekedwe awiri a Optical Ethernet.
Mapangidwe a Gigabit Ethernet/STM-4 converter amagwirizana ndi ITU-T komanso zofunikira za SDH zoperekedwa ndi Ministry of Information Industry, China.
BD-EOS-GE/STM-4 imanyamula ma data kudzera pa chidebe mu SDH, pozindikira gigabit Ethernet pa SDH.
Chipangizocho chimagwiritsa ntchito 19 ″ rack ya 1U yokwera, yomwe imatha kuyikidwa pakompyuta kapena kuyika mu kabati ya 2.2m kapena 2.6m kutalika, ndipo imatha kuyendetsa mwachindunji ma alarm omwe ali pamwamba.
Chipangizocho chikhoza kuyendetsedwa ndi zosankha zitatu zamphamvu: AC ~ 220V, DC -48V, ndi AC ~ 220V yokhala ndi zosunga zobwezeretsera za DC-48V.
Mawonekedwe

Kupereka mawonekedwe owoneka bwino a STM-4 omwe amagwirizana ndi G.707
Thandizani ma doko awiri a STM-4 (1 + 1 doko loyang'ana teteza)
Kupereka madoko awiri amagetsi a gigabit Efaneti ndi mawonekedwe awiri owoneka bwino a gigabit Efaneti (ngati mukufuna);
Kuphatikizika kothandizira kwa ntchito ya Ethernet, chithandizo chachikulu cha 252: 1
Kuthandizira ma protocol a Efaneti : IEEE 802.3/3u/3x/3z/1q
Thandizani ma CD wamba a HDLC/GFP.
Za mawonekedwe abwino kwambiri a synchronous;
Ndi DC-48V/AC220V kusankha kwa magetsi;
Kupereka mawonekedwe awiri owoneka bwino a STM-4 ndi mawonekedwe awiri a gigabit Ethernet;
Kuyika pachimake ndi kutalika 1U ndi m'lifupi 19”, akhoza kuikidwa pa desiki kapena wokwera mu kabati kapena moyikamo kutalika 2.2 m kapena 2.6 m;
Mawonekedwe owoneka bwino ndi SFP;
Kuthandizira kasamalidwe ka CLI;
chipangizo kupereka wolemera alamu chizindikiro;
