STM-1 to Gigabit Ethernet Aggregation Converter

Gigabit Ethernet - STM-1 - E1 Convergence Protocol Conversion System with WEB server management

SPOTLIGHT:
This GE-STM-1 convergence protocol conversion system converts 63 channels of E1 ports from standard SDH STM-1 optical port to two 1000M Ethernet ports for communication - and every two E1 channels support ring networking.

DESCRIPTION:
This GE-STM-1 convergence protocol conversion system converts 63 channels of E1 ports from standard SDH STM-1 optical port to two 1000M Ethernet ports for communication; and every two E1 channels support ring networking. It can be extensively used in the convergence data comprehensive access system with multiple branch nodes network for operators, power, finance, public security organs, procuratorial organs and people's courts.

Main Features
The 1U and 19 inches structures are available, which can save machine room space greatly, decrease networking wiring, optimize network structure and improve the stability and performance of system.

The two channels of standard STM-1 ports can work under the 1+1 lower order channel protection mode; both master clock and slave clock modes are supported, and under the slave clock mode, it supports the automatic shifting of clock sources.

The two 1000M Ethernet data converging ports can support GE electrical port (RJ45) and GE optical port (SFP) modes; The Ethernet supports 10/100M/1000M, semi-duplex, full-duplex and adaptive modes with VLAN, QinQ and PAUSE functions.

The CONSOLE interface and WEB server management interface are provided to conduct out-band Ethernet management and in-band E1 management, facilitating the local and remote software upgrade and maintenance of equipment by users.

The internal E1 channel can be set to non-frame and frame modes, and the frame mode supports N*64K sub-rate access; and each E1 supports local/remote loopback, and pseudo-random code testing function; data package receiving, sending and flow statistics functions can be conducted for each individual E1;

Every two E1 channels can support ring networking and ring network protection and switching functions;

It can implement the Trunk function of 1000M Ethernet;

It supports dual-power redundant standby to implement combined AC220V/48V dual-power backup as required.
