2. Overview
OPCOM3100-155 is compact SDH Multi-Service access equipment developed
by Raisecom, technical feature and indexes meet every norm of ITU-T and
national SDH. It deploys 1U structure, and it can provide STM-1, E1 and
Ethernet service. It is suitable for the access of end business of Telecom.
OPCOM3100-155 is mainly applied to service access and transmission of
access layer in communication networks; it also can make up communication
networks through E1 interface together with access devices, GSM mobile
cellular base station, ETS wireless access base station, switches and routers.
OPCOM3100-155 is available for flexible topology: point-to-point, chain and
ring and supports 1+1 low path protection to guarantee high reliable
transportation.
You can manage OPCOM3100-155 by in-band or out-of-band network
management channel; Raisecom network management platforms NVIEW and
NNM are also available for figure information of monitoring, alarms,
management and maintenance.
