MetroConnect supporting Multiple Ethernet Demarcation LAN Extension Devices

MetroConnect Solution for Ethernet Service Demarcation

This application shows an MC12000 MetroConnect chassis with WCC1800 modules, supporting multiple WCM1800 Ethernet over up to 8 Fractional E1/T1 LAN Extension Demarcation Devices. The MetroConnect and WCM1800 together offer LAN Extension and Ethernet demarcation, with remote management via 802.3ah OAM. Various service delivery options are available including fibre, copper, and fibre plus copper over up to 8 Fractional E1/T1 circuits. Comprehensive remote network management access is available via the MetroConnect including end to end remote management using 802.3ah OAM. 10M, 100M and Gigabit Ethernet applications can all be supported, as can Jumbo frames.

WCM1800 delivering Ethernet services from an MPLS core network

This application shows an WCM1800 unit being used as the Ethernet demarcation device to deliver a Carrier Ethernet service from an MPLS core network. A wide choice of Ethernet connectivity is available for the user via the 10/100/1000baseT and SFP fibre ports. OAM support means that the WCM1800 can be remotely managed by the central network management system using standards based OAM packets. GFP is supported allowing single ended use with aggregation platforms in the core network.

This application shows how a pair of WCM1800 units can be used to offer Ethernet service demarcation and LAN Extension functionality either over up to 8 Fractional E1/T1 circuits.

WCM1800 units performing aggregation of services on multiple sites

This application shows how VLANs can also be used to select which site to forward user data to, e.g. when using a WCM1800 unit supporting eight E1 ports at a central site supporting up to four sites with WCM1100, WCM1400 or WCM1800 units each supporting up to eight E1 ports.

The WCM1800 is a switching media converter operating in store and forward mode. The WCM1800 supports auto-negotiation, and auto MDI/MDIX cross-over switching on the copper interface.

To ensure reliable operation, the WCM1800 supports Link State Forwarding, whereby a fault on the serial port will automatically force a link down on the user ports to indicate to the attached device that there is a link problem.

The WCM1800 supports the transmission of Jumbo frames.

The WCM1800 supports 802.3ah OAM which means that the Ethernet service can be managed and monitored right up to the customer delivery point. The future WCM1800 development roadmap includes support for RSTP, IEEE802.3ad with LACP support, IEEE802.1ag and Y.1731 OAM standards.

The WCM1800 is provided with an SFP module with LC connector supporting for example 1000Base-SX for 550 metres operation over multi-mode fibre, or 1000Base-LX for up to 10km over a single-mode fibre.

The WCM1800 is ordered without an SFP fitted, although customers can subsequently change their interface type. Please contact Metrodata for price and availability of SFP modules including long haul, 1550nm, bi-directional and CWDM.

The WCM1800 is available in a choice of 100-250 VAC or -48 VDC integrated power supplies.

The WCM1800 can easily be rackmounted in either a 1U two unit rackmount kit, a 6U eighteen unit rackmount kit.

The WCM1800 is part of a wide range of LAN extension products from Metrodata.
