Page 12: Introduction
WCM1100, WCM3100, WCM-Serial, LHM1000 and LVM2000 will be used for product specific areas. The Metrodata WCM allows for the extension of an Ethernet Service over a Wide Area Network Connection. The WCM is a managed unit allowing for the effective demarcation between LAN and WAN services.
Page 13 METRODATA LTD 13 of 169 WCM1100 / WCM3100 / WCM-Serial / LHM1000 / LVM2000 User Manual The WCM supports either IP DSCP, or IEEE802.1p based traffic prioritisation with outgoing traffic being queued in one of four priority queues. The WCM supports link OAM, IEEE802.3ah and RSTP for loop prevention.
