Multi-service SDH STM-1 Add Drop Multiplexer

Kufotokozera Kwachidule:

Overview The STM-1 add & drop multiplexer delivers bonded E1 lines, Ethernet services and V.35links over legacy SDH networks. Installed at the customer site or directly on  STM-1 access ring, ESDH155ADM leverages the SDH infrastructure for LAN connectivity and Internet access, while providing leased line services to end users. Moreover, interoperating with EZWELL ESDH-MSAP and ESDH155TM series, ESDH155ADM offers an innovative and competitive solution to reduce OPEX and CAPEX for carriers or ISPs. The Ethernet frames are encapsulated in SDH frame by using GFP (Generic Frame Protocol) and transported through the SDH network in a VC-12 group, configuring the bandwidth of IP channel in increments of…

    Pulogalamu yaSTM-1 kuwonjezera & kusiya multiplexeramapereka chomangiraMizere ya E1,Ntchito za EthernetndipoV.35kulumikizana ndi maukonde amtundu wa SDH. Kuyikidwa patsamba la kasitomala kapena mwachindunji pa mphete yolumikizira ya STM-1, ESDH155ADM imagwiritsa ntchito zida za SDH zolumikizira LAN ndi intaneti, pomwe ikupereka mwayi wothandizira anthu otsiriza. Kuphatikiza apo, kuyanjana ndi EZWELL ESDH-MSAP ndi ESDH155 TM mndandanda, ESDH155ADM imapereka njira yatsopano komanso yotsutsana kuti ichepetse OPEX ndi CAPEX kwaonyamula kapena ISPs.

    Mafelemu a Ethernet adakulungidwa mu SDH chimango pogwiritsa ntchito GFP (Generic Frame Protocol) ndikunyamula kudzera pa netiweki ya SDH pagulu la VC-12, ndikukonza njira yolumikizira njira ya IP pakuwonjezera kwa 2Mbps. ESDH155ADM imayambitsa ukadaulo wa LCAS ndi ukadaulo wa VCAT kuti ipindulitse netiweki ya SDH kuti ikwaniritse bwino kuchuluka kwama data. Gawo lililonse la Ethernet limakonzekera mpaka ma WAN awiri, kuphatikiza mautumiki awiri a Ethernet mumanetiweki a SDH. Magalimoto a PDH ndi magalimoto a V.35 ajambulidwa mu chimango cha SDH; kumapangitsa ulalo wa E1 ndi V.35 kuti athandizire kulumikizana, ndipo amatha kuthetsedwa nthawi iliyonse pa netiweki.

    Njira ziwiri zoyendetsera zilipo: CONSOLE ndi SNMP. Dongosolo la kasamalidwe ka netiweki la EZWELL EMS limathandizira kukonza ndi kuwunika kwakutali, kuchepetsa kugwiritsa ntchito ndalama, kuchotsa kuyendera ukadaulo ndikukweza magwiridwe antchito amtaneti ndi nthawi yokwanira.
