FEATURES
• Connect 10BaseT and 100BaseT LANs and VLANs over E1 or T1 services
• Integrated IP router for connecting IP domains over E1/T1 services
• 10/100BaseT bridge supporting IEEE 802.3x flow control and back pressure
• Diagnostic loopback activation in compliance with ITU V.54 standard
• Plug and play
DESCRIPTION
• RIC-E1 and RIC-T1 interface converters enable communication between devices with E1/T1 interfaces and equipment with V.35, X.21, V.36, RS-530 interfaces.
• When equipped with IR-ETH/QN interface module, RIC-E1 and RIC-T1 transparently connect remote LANs and VLANs over unframed E1/T1 links utilizing the full E1/T1 bandwidth. The IR-ETH/QN interface modules support autonegotiation, allowing connection without additional configuration.
• RIC-E1 and RIC-T1 equipped with the IR-IP interface module operate as IP gateways, forwarding IP packets destined to the IP network. This prevents broadcast to the WAN and enables the LAN users to register for an IP multicast service.
• RIC-E1 and RIC-T1 feature front panel LEDs to indicate transmit/receive activity, E1/T1 signal loss condition and diagnostic loopback operation.
The rear panel LEDs of the Ethernet interface modules indicate the LAN status and activity.
• RIC-E1 and RIC-T1 are also available as plug-in cards for RADís ASM-MN-214, 19-inch card cage.
