Description
Ethernet over STM-1 is a technology that enables the transmission of Ethernet frames over a Synchronous Transport Module level 1 (STM-1) network. This approach allows for efficient utilization of the STM-1 bandwidth, which can carry up to 16 E1 channels. By encapsulating Ethernet packets within the STM-1 framework, service providers can deliver high-speed data services while leveraging existing telecommunications infrastructure. The SDH optical terminal multiplexer supports various applications, including internet access and private networking, making it a versatile solution for modern communication needs. The ability to transport both Ethernet and E1 traffic over a single STM-1 link enhances network efficiency and reduces operational costs.
The E1 Ethernet over STM1 transmission system is multi-service Synchronous Digital Hierarchy (SDH) transmission system compatible with ITU-T standard. It is designed as a modular system with two 155.520Mb/s optical interfaces to provide an ultra-compact, cost-effective and flexible multi-service platform. With optional cards such as E1 card and Ethernet card, it is easy to meet user’s various requirements. The SDH optical terminal equipement provides fully cross connectivity between all tributaries, and can be used as a Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.
