RICi-4E1, RICi-4T1, RICi-8E1, RICi-8T1 Fast Ethernet over Multiple E1/T1 Lines Network Termination Units DESCRIPTION • RIC-4E1, RIC-4T1, RIC-8E1 and RIC-8T1 are Network Termination Units (NTU) connecting Fast Ethernet LANs over four or eight bonded E1 or T1 circuits. They enable service providers to supply transparent Ethernet services. The devices can also be used for transparent connection of corporate LANs over existing E1 or T1 lines. • Up to four or eight E1 or T1 lines are bonded together using Multi-Link PPP (ML-PPP) creating a large virtual pipe. FEATURES • Configurable Maximum Transmit Unit (MTU) for the • The devices can be used in a • Connect Fast Ethernet LANs point-to-point application or in a delay versus throughput over up to four or eight hub-and-spoke topology, control bonded E1 or T1 circuits operating opposite the Egate-100 • Inband and out-of-band gateway.
