INFORMATION
The Gigabit Ethernet/STM-4 Converter (BD-EOS-GE/STM-4 in short hereafter) takes SDH technology as its core to provide access, convergence, transmission and management functions of TDM services and broadband IP services, and is a device for comprehensive access conversion in the applications of conventional telecommunicating services and broadband data services.
The gigabit Ethernet to STM-4 converter is an Ethernet over SDH interface conversion equipment supplied with two STM-4 optical interface, two electrical Ethernet and two Optical Ethernet interface.
The design of Gigabit Ethernet/STM-4 converter complies with ITU-T and the relevant SDH specifications issued by Ministry of Information Industry, China.
The BD-EOS-GE/STM-4 carries the data services via the container in SDH, realizing the gigabit Ethernet over SDH.
The device applies 19" rack of 1U high, which can be placed on the desktop or installed in a cabinet of 2.2m or 2.6m high, and can directly drive the top-mounted aural-visual alarm unit.
The device can be powered by three power choice: AC ~220V, DC -48V, and AC ~220V with DC-48V backup.

Application
General customer's questions about the GE/STM-4 converter:
question1: Can baudcom's GE to STM-4 converter device work with other supplier's SDH device?
answer: Baudcom’s GE/STM-4 EOS converter can work by pairs (two units are all from BAUDCOM) or work with other vender’s SDH device. Baudcom's GE to STM4 converter device (BD-EOS-GE/STM-4) is designed by ITUT standards.The STM-4 is made of VC4. The GE/STM-4 EOS device can be compatible with most of the SDH devices from other suppliers.Baudcom's Gigabit ethernet over STM4 EOS converter has successfully worked with many company's SDH device,for example,Huawei,Alcatel-lucent,ZTE (zhongxing),UT STARCOM,TATA etc.
Question2: Can the GE/STM-4 (GE over STM-4) converter device be managed?
Answer: The GE/STM-4 (GE over STM-4) converter device can be managed by TELNET. User can check the device’s work status by the TENET. User also can configure the device’s functions (Ethernet ports features,STM-1 ports features etc) by the TELNET management. User can manage the device by the TELNET in local or remote location. The TELNET management is easy and convenient for user manage the device.
Question3: Does the Gigabit Ethernet to STM-4 SDH converter support SNMP management?
Answer: The device can not be managed by the SNMP management now. Our engineers are designing the management function,the device will support the SNMP function in the future.
Question4: Does the GE/STM-4 SDH converter support VC12?
Answer: The ethernet over STM-4 SDH device can only support VC4.If you need VC12 encapsulation,you can choose Baudcom's GE/STM-1 converter device .
Question5: Does the Gigabit ethernet to STM4 converter support SNCP?
Answer: The ethernet to STM-4 SDH converter don't support SNCP function.BAUDCOM's SDH multiplexer can support the SNCP function .
