Multi-service SDH STM-1 Add Drop Multiplexer

Multi-service SDH STM-1 Add Drop Multiplexer

Description:

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…

    Overview

    TheSTM-1 addendi & stilla multiplexerdelivers bondedE1 lines,Aer officiaetV.35Nexus super legatum SDH retiacula. Ad locum emptoris inauguratum vel directum in anulum STM-1 accessum, ESDH155ADM substructionem SDH levat pro connectivity LAN et interreti accessu, dum recta officia ad finem utentium locanda curavit. Praeterea, in opere cum seriei EZWELL ESDH-MSAP et ESDH155TM, ESDH155ADM praebet solutionem innovative ac competitive reducendi OPEX et CAPEX pro vehiculis vel ISPs.

    Tabulae Ethernet in SDH compage includuntur utendo GFP (Protocollo Frame Generico) et per SDH retis in circulo VC 12 transportantur, band latitudinem canalis IP configurantes in incrementis 2Mbps. ESDH155ADM inducit technologiam LCAS et VCAT technologiam ut SDH retis prodesse ut melius apta negotiatio notitiarum negotiorum fiat. Quilibet Aer sponsus moduli ad duos WANs, coniungens duas directiones officia Aernei in SDH retiaculis. Negotiatio PDH et V.35 negotiatio in SDH artus decisa sunt; efficere nexum E1 et V.35 ut nexum crucis sustineant, et quovis puncto in ornatum terminari possunt.

    Duae rationes administrationis in promptu sunt: CONSOLE et SNMP. The EZWELL EMS administratio retis ratio sustinet configurationem remotam et vigilantiam, expensas operativas reducens, technicas visitationes tollendas et retis perficiendi et uptime maximisando.
