The RICI-T1/H is a hardened version of the Fast Ethernet over T1 intelligent converter and has a wide range 100 – 240 VAC or 48/60 VDC power supply with temperature hardened plastic enclosure, T1 port and 10/100 BaseT port. brbr TheRICi-T1 is an intelligent converters connecting Fast Ethernet LANs over full or fractional T1 circuits. They enable service providers and ISPs to supply transparent Ethernet services, without interfering with user traffic. The RICi-T1 complies with RAD's unique set of EtherAccess features. This feature set provides services and carrier backhaul applications over low and high-speed SDH/SONET and PDH circuits, from fractional and full T1 or T3 over STM-1/STM-4 to Gigabit Ethernet. brbr The RICi-E1 and RICi-T1 are equipped with one E1/T1 port and one 10/100 BaseTx port. Packets are forwarded from the Ethernet network to the TDM network at wire speed, fully utilizing the expensive TDM circuit bandwidth. The VLAN Priority bits (802.1p) and IP Precedence priority schemes enable users to define four different QoS levels, according to the application requirements. Features include wire-speed packet forwarding, 4 levels of QoS, based on four VLAN priority queues in accordance with 802.1p and IP Precedence, In band and out-of-band management access via ASCII terminal, Web browser, Telnet, or SNMP, Plug-and-play using DHCP client, VLAN stacking and tagging, keeping ethernet user traffic completely separate from management data, while maintaining user VLAN settings intact.
