Features

Ethernet® OAM

Supported with : XGMC-2016 Series

Ethernet OAM is a standard technology based on ITU-T Y.1731, IEEE802.1ag.Network Monitering, Loopback Test, Failure Notification and other functions are available between products that support the standard.

Functions : CC (Continuity Check) for network connectivity, LB (Loop Back) for Layer2 ping and others.

Fast Link Relay (Link Pass Through)

Supported with : eWAVE Series, GMX Series, XGMC Series

Fast Link Relay is also known as Link Path Through. It automatically turns off optical power when detecting a failure on long haul or remote user ports.

Inband Management

Supported with : eWAVE Series, GMX Series, GMC Series, XGMC Series

IFS : Inter-Frame Signaling
· Operation, Administration and Maintenance (OAM) messages are embeded into Inter-Frame Gap and no influence on data plane.
· Inter-Frame Signaling (IFS) messages include fault notification and other communications.

Bit Error Rate (BER) Monitoring

Supported with : XGMC Series, eWAVE Series, GMX Series, GMC Series

It detects fiber deterioration before link fails. BER threshold is configurable (above 10^12) and SNMP trap is transmitted.

Digital Wrapper

Supported with : eWAVE Series, XGMC-2016 (LDW)

Digital Wrapper is a frame format standardized in ITUT*1 G.709 for optical transport network. It uses channel header and FEC*2 for wrapping data. FEC provides real time error correction function for stable long distance transmission and receiving sensitivity improvement.

*1 ITU-T=International Telecommunication Union Telecommunication Standardization Sector
*2 FEC=Forward Error Correction

Loopback

Supported with : eWAVE Series, GMC Series, GMC Series, XGMC Series

It verifies Long Haul (MUX/LH) connectivety.
