Introduction
1.1 Overview
RICi-622GE is a network termination unit (NTU) that provides simple, efficient,
and cost effective Gigabit Ethernet connectivity over SDH/SONET networks. The
device can aggregate traffic from up to eight remote SDH/SONET sites. The unit
offers a migration path for connecting future-ready IP devices to the existing
SDH/SONET networks at up to 1.2 Gbps access rates. RICi-622GE enables
cost-effective deployment of the SDH/SONET infrastructure for Internet access
and LAN connectivity, while providing continued support for all legacy services.
The unit delivers carrier-grade Ethernet services as defined by the MEF:
• EPL (Ethernet Private Line)
• EVPL (Ethernet Virtual Private Line).
RICi-622GE has two Gigabit Ethernet ports and two STM-4/OC-12 ports that
support SFP-based fiber optic connectors. The Ethernet ports can also be ordered
with 10/100/1000BaseT interfaces. The STM-4/OC-12 ports offer either
622 Mbps with link bonding using VCAT (G.707/Y.1322) and LCAS (G.7042), or
1+1 link protection (unidirectional MSP/APS) to increase service uptime. The
Gigabit Ethernet ports offer redundancy based on link aggregation (802.3ad).
The unit supports powerful bandwidth profiles including CIR/CBS and EIR/EBS for
differentiated Ethernet services. RICi-622GE supports encapsulation using GFP per
ITU-T Rec. G.7041 or LAPS per ITU-T Rec. X.86, providing efficient bandwidth
utilization.
RICi-622GE can be managed via a local terminal port, via a dedicated out-of-band
Ethernet port, or inband through a user or network port. The device supports
Network Time Protocol and can obtain the time of day from a standard SNTP
server. RICi-622GE has two redundant power supplies, increasing its reliability.
Product Options
Gigabit Ethernet Ports
The two Gigabit Ethernet ports are available with the following interfaces:
• 1000BaseSx, LC connector (SFP)
• 1000BaseLx10, LC connector (SFP)
• 10/100/1000BaseT, RJ-45 connector.
The fiber optic interfaces support industry-standard Gigabit SFP hot-swappable
optical transceivers. The two ports must be either both fiber optic interface or
