RIC-155GE from RAD
RIC-155GE Network Terminal unit (NTU) bridges between Gigabit Ethernet and STM-1/OC-3c SDH/SONET networks.
Typical applications for the RIC-155GE from RAD are:
- Transparent LAN services (see Figure 1)
- Enterprise connection
- Low–cost alternative to STM-1/OC-3c router interface.
The RIC-155GE bridge operates in two forwarding modes:
- VLAN-unaware MAC address learning
- VLAN-aware mode; Double tagging ensures transparency of user VLAN and traffic separation between Gigabit Ethernet user traffic
and Fast Ethernet management traffic.
Based on VLAN priority tagging, four priority queues can be defined to prioritize between users or user applications. (VLAN-aware
mode only). Ethernet encapsulation over STM-1/OC-3c is performed by mapping Ethernet frames directly over HDLC framing, resulting
in high throughput. Fault propagation of SDH/SONET alarms can optionally propagate and bring down the Gigabit Ethernet link. GbE
link alarms can optionally propagate and trigger alarms over the SDH/SONET. Setup of the RIC-155GE, control, and monitoring
performed either inband, within the Ethernet flow, or out-of-band using a dedicated Ethernet port or the terminal control port.
RAD RIC-155GE Management options include:
- ASCII terminal
- Telnet server
- ConfiguRAD via a Web browser
- RADview-Lite SNMP based fault management service package, with ConfiguRAD element manager.
The RIC-155GE Gigabit Ethernet link is available with fiber optic or electrical interfaces.
Comprehensive diagnostic capabilities include:
- Real-time alarms to alert user on fault conditions. Alarms are reported to the management station, recorded in the log file,
and simultaneously relayed via a dry contact port.
- Ethernet and SDH/SONET link monitoring
