Ethernet Bridge
Introduction
Spacecom 4×E1/10/100BaseT series are user-end accessing equipments developed and produced with Spacecoms self-developed special-purpose integrated circuits. They are used for Ethernet data that takes super-large special-purpose integrated circuits as the core to realize user data accessing via E1 transmission network, so that Ethernet data can be
transmitted over multiple E1s, breaking the bandwidth restriction of single E1. They can easily leverage the rich existing E1 resources in the public network to build broadband Ethernet data network rapidly.
Spacecom 4×E1/10/100BaseT series has no special requirements for E1 channel, and can automatically tolerate errors from E1 . Even if some E1 channels fail, only the equipments data throughput can be reduced, no interruption of the transmission of data. They can be flexibly configured and easily maintained, and at the same time can provide complete network management capabilities.
