2. Overview
RC953-FE4E1/8E1 (RC953-FX4E1/8E1) is Inverse Multiplexer which delivers Ethernet
services over existing TDM transportation network. These equipments can be used in
point-to-point topology and hub-and-spoke topology with RC953-8FE16E1 located in the
central office. RC953-FE4E1 (RC953-FX4E1) allows the transmission of fast Ethernet
over 4 bonded E1 circuits (8M) and RC953-FE8E1 (RC953-FX8E1) allows the
transmission of fast Ethernet over up to 8 bonded E1 circuits (up to 16M). There is optical
option for fast Ethernet port to provide an economical path towards extending the distance
of an existing Ethernet network. Additionally its advanced features such as automatic E1
link adjustment provide our carriers a cost-effective, flexible and reliable solution for
high-quality Ethernet Service delivery by using TDM network resources.
