Ethernet over SDH – Flexible Ethernet via resilient SDH Networks
In contrast an increasing number of terminal equipment is however only being developed with an Ethernet interface. Therefore network operators have to forward Ethernet data streams via SDH networks more and more often. By employing special functions, the asynchronous Ethernet packages have to be converted into a synchronous SDH data stream.
When using EoS (Ethernet over SDH), the Ethernet frames are enclosed in SDH in line with GFP (Generic Frame Protocol) and conveyed by SDH in VC-12 or VC-3 groups (virtual container). EoS transmission complies with the relevant ITU-T standards and allows transparent interaction with conventional SDH networks, as well as any other EoS standard compliant system.
XMC20 is a platform for mission-critical networks that combines Ethernet, SDH and PDH technology in one single subrack. It's designed to handle the specific requirements of dedicated networks.
Ethernet-over-SDH functions allow TDM and Ethernet services to be transmitted over an SDH network. As a result, the XMC20 platform is flexible to integrate into SDH and Ethernet networks, allowing seamless migration to a fully Ethernet-based network. STM-16/STM-4/STM-1 interfaces are available for the uplink.
UMUX is a Multi-Service Access system that can provide a variety of applications for dedicated network operators. The UMUX family is especially equipped for cross-connect systems with an STM-4 multiplex system and a wide range of subscriber interfaces, including integrated Ethernet support.
