RICi-4E1, RICi-4T1, RICi-8E1, RICi-8T1
Fast Ethernet over Multiple E1/T1 Lines Network Termination Units .
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.
FEATURES :
- Connect Fast Ethernet LANs over up to four or eight bonded E1 or T1 circuits
- Bond four or eight E1 or T1 ports utilizing Multi-Link PPP (ML-PPP bridge mode) bridging the bandwidth gap between E1/T1 and E3/T3
- Up to 50 ms differential delay compensation
- Four 10/100BaseT ports (Fast Ethernet)
- Enable transparent forwarding of Ethernet user traffic and provides secure management, via VLAN stacking and striping
- Transparent MAC forwarding
- Configurable Maximum Transmit Unit (MTU) for the delay versus throughput control
- Inband and out-of-band management access via: ASCII terminal ,Web browser, Telnet ,SNMP, including RADview-Lite
- Four levels of QoS, based on four VLAN priority queues as per 802.1p or DSCP
- Monitoring and diagnostic tools on TDM and Ethernet ports for quick fault isolation
- Fault propagation of E1 or T1 error conditions to Ethernet port
- Interoperable with RAD’s Egate-100 edge gateway
- The 802.1p and DSCP priority scheme enables users to define
- VLAN tagging, stacking and striping option at ingress and egress enables transporting user traffic transparently, keeping all the user VLAN settings intact. In addition, the management traffic may be tagged with a different VLAN, fully separating user traffic from management data.
Typical applications :
- Ethernet private Line/LAN services
- IP DSLAM, cellular IP and WiMAX base station backhauling
- Interoffice or enterprise LAN connection
