MetroConnect supporting Multiple Ethernet Demarcation LAN Extension Devices

MetroConnect Solution for Ethernet Service Demarcation

This application shows how WCC1800 modules within a MetroConnect chassis can be used to perform an Ethernet over 8-port Fractional E1/T1 LAN Extension function. Electrical connection into the core network potentially improves port density and therefore utilisation levels, but fibre connectivity is also available. The WCM1800 is a standalone version of the WCC1800 module offering Ethernet service demarcation at the customer site.

The WCC1800 is an I/O module for use in the MetroConnect system.

The WCC1800 occupies a double slot in the MetroConnect MC12000 or MetroRack chassis and is fully “Hot Swap” compliant to ease maintenance and the provisioning of new services.

Each Module supports Ethernet over 8-port Fractional E1/T1 LAN Extension and Ethernet Demarcation functionality and supports Copper, Fibre or Copper and Fibre over up to 8-port Fractional E1/T1 operating modes. Link Loss transparency / forwarding is supported.

Optionally, the WCC1800 may be enabled to support OAM link management according to IEEE802.3ah. When OAM is disabled, the WCC1800 operates in a fully transparent LAN Extension mode.

The future WCC1800 development roadmap includes support for IEEE802.1ag and Y.1731 OAM standards.

The SFP port auto senses the SFP type inserted, based on the Module Definition and configures the port for 100BaseFX or 1000Base-X operation.

The WCC1800 supports auto-negotiation, and auto MDI/MDIX cross-over switching on the copper interface.

The WCC1800 supports the transmission of Jumbo frames.

Other SFPs are available on request including long haul, 1550nm, CWDM and bi-directional.

Whilst the MetroConnect product range uses industry standard user exchangeable SFPs, it is recommended that these are purchased from Metrodata to guarantee their specification and compatibilty with each other.

If you require another SFP please contact our sales team with your requirements.
